Hub-and-Spoke vs Point-to-Point

Airline networks are often described as if there are only two choices:

hub-and-spoke

or:

point-to-point

Reality is more interesting.

A hub airline can operate nonstop flights between secondary cities.

A point-to-point airline can carry connecting passengers.

An airport can be a major operating base without functioning like a traditional connecting hub.

And the same airline group can deliberately operate:

• Hub networks
• Point-to-point networks
• Regional feeder systems
• Alliance connections

at the same time.

The most useful distinction is not:

connections versus no connections

It is:

Does the airline intentionally concentrate traffic through a small number of transfer points, or does it build more of its network around demand between individual origin-and-destination markets?

Start With Origin and Destination#

Airlines commonly think about passenger demand in terms of:

origin and destination — O&D

Suppose a passenger travels:

Chennai → Frankfurt → Boston

The flights are:

• Chennai → Frankfurt
• Frankfurt → Boston

But the passenger's true market is:

Chennai → Boston

Frankfurt is the connection point.

That distinction becomes fundamental when designing an airline network.

Local Passenger Versus Connecting Passenger#

A flight from Chennai to Frankfurt can carry two broad kinds of passenger.

Local passenger#

Their journey ends in Frankfurt.

Their O&D is:

Chennai → Frankfurt

Connecting passenger#

They continue somewhere else.

Their O&D might be:

Chennai → Boston

or:

Chennai → Stockholm

The same physical Chennai-Frankfurt flight can therefore serve dozens of different passenger markets.

That is the economic power of a hub.

What Is a Hub-and-Spoke Network?#

A hub-and-spoke network concentrates a significant amount of an airline's traffic through one or more hub airports.

The hub sits in the middle.

The routes radiating from it are the spokes.

Conceptually:

A ─┐
B ─┤
C ─┼── HUB ──┬─ D
E ─┤         ├─ F
G ─┘         └─ H

Passengers can travel:

A → Hub → D

even when the airline does not operate:

A → D nonstop

That allows demand from many small markets to be combined onto the same flights.

What Is a Point-to-Point Network?#

A point-to-point airline route is built more directly around traffic between individual city pairs rather than requiring most journeys to flow through one or a few central transfer hubs.

Conceptually:

A ───── B
A ───── C
B ───── D
C ───── E
D ───── F

The airline chooses routes where sufficient demand exists between the points it wants to serve.

But this does not mean:

• Every passenger flies nonstop
• The airline never carries connections
• The airline has no large operating bases
• Every route is independent from every other route

Point-to-point describes the structure of the network.

It is not a promise that every customer avoids a connection.

Point-to-Point Is Not the Same as Nonstop#

This is the most important correction to the usual explanation.

Nonstop#

Describes one passenger itinerary or flight:

A → B

with no intermediate landing.

Point-to-point#

Describes how an airline designs its broader route network.

A point-to-point airline can still sell:

A → B → C

to a passenger connecting at B.

The difference is that B may be one of many useful connection points rather than one dominant hub through which the airline intentionally funnels most traffic.

Point-to-Point Is Also Not the Same as "Direct Flight"#

In airline terminology:

nonstop and direct are not perfect synonyms.

A nonstop flight makes no intermediate stop.

A direct flight traditionally retains the same flight number between origin and destination but can potentially make an intermediate stop.

So for network discussions, nonstop is usually the clearer word when that is what we mean.

What Makes a Hub a Hub?#

A hub is more than: "an airport where an airline has lots of flights."

A hub is used strategically to create connecting flows.

The airline schedules routes so traffic arriving from multiple origins can transfer onto flights serving multiple destinations.

That requires coordination among:

• Schedule planning
• Gates
• Baggage
• Crew
• Aircraft
• Airport operations
• Revenue management

Hub Versus Focus City#

An airline can have a large operation at an airport without treating it as a traditional hub.

A focus city generally has:

• Many airline routes
• Significant local demand
• Potential connecting opportunities

but less deliberate connection dependence than a major hub.

The boundary is not mathematically precise.

It is an airline-strategy description.

Hub Versus Crew Base#

A crew base answers:

Where are pilots or cabin crew based?

A hub answers:

Where is the network deliberately concentrating passenger flows?

Those can be the same airport.

They do not have to be.

Hub Versus Maintenance Base#

Likewise, a maintenance base is an airport where an airline concentrates maintenance capability.

A hub can support maintenance economies of scale.

But:

maintenance base ≠ hub by definition

The Connectivity Math Behind Hubs#

Suppose an airline connects:

50 spoke cities

to one hub.

Each spoke needs one link to the hub:

50 spoke-hub city-pair links

Yet passengers can potentially travel between every pair of spoke cities with one connection.

The number of unique, undirected spoke pairs is:

n(n - 1) / 2

For:

n = 50

that becomes:

50 × 49 / 2 = 1,225

So 50 spokes can theoretically create:

1,225 spoke-to-spoke O&D pairs

through one hub.

Direction Matters Too#

If we count:

A → B

and:

B → A

as separate directional markets, the number becomes:

n(n - 1)

For 50 spokes:

50 × 49 = 2,450

directional O&Ds.

That distinction explains why published network-connectivity numbers can look different.

The Formula Is Only Potential Connectivity#

A hub does not magically make all 1,225 pairs commercially useful.

A valid connection still needs:

• Suitable arrival time
• Suitable departure time
• Enough connection time
• Legal/immigration feasibility
• Available seats
• A commercially viable fare
• Passenger demand

So the formula tells us:

potential network connectivity

not:

1,225 guaranteed useful itineraries.

Full Mesh Versus Hub#

To connect 50 cities to every other city with individual nonstop links would theoretically require:

50 × 49 / 2 = 1,225

unique nonstop city-pair links.

A hub structure can create one-stop connectivity among those same 50 spokes using only:

50 spoke-hub links

assuming the hub is additional to those spoke cities and schedules make the connections possible.

That is the central network advantage.

The airline combines demand rather than trying to support every thin city pair with a dedicated nonstop.

Hub Banks#

Many hubs improve connectivity using banks or waves.

The basic pattern is:

1. Many flights arrive.
2. Passengers and bags transfer.
3. Many flights depart.

This creates a large number of connections within a limited period.

Arrival Bank#

A group of inbound flights reaches the hub around the same period.

Passengers arrive from:

• Small spokes
• Large domestic markets
• International markets

Connection Window#

The airport needs enough time for:

• Passenger movement
• Security where required
• Immigration where required
• Baggage transfer
• Boarding

Every airport and itinerary has minimum-connection requirements.

There is no universal:

60- or 90-minute hub bank

that applies everywhere.

Departure Bank#

After the connection window, another wave of flights departs.

One arrival can therefore feed passengers into many outbound services.

And each outbound service collects passengers from many inbound flights.

This creates the hub's multiplier effect.

Why Bank Flights?#

Suppose ten flights arrive randomly throughout the day.

If their onward flights depart before they arrive:

they do not connect usefully.

If those same flights are deliberately timed together:

many connection combinations become sellable.

Airlines therefore optimize not just:

where they fly

but:

when flights intersect.

Banked Hub Versus Rolling Hub#

Not every hub uses sharply defined banks.

Highly banked hub#

Flights arrive and depart in concentrated waves.

Advantages:

• More connection combinations
• Shorter scheduled connection times

Costs:

• Gate peaks
• Runway peaks
• Baggage peaks
• Staffing peaks
• Greater sensitivity to disruption

Rolling or depeaked hub#

Flights are distributed more evenly.

Advantages can include:

• Better infrastructure utilization
• Less extreme congestion
• More stable ground operation

The tradeoff can be:

• Longer connections
• Less concentrated connectivity

Airlines can move between these strategies over time.

Why Hub Size Matters#

More spokes can produce more possible markets.

But hub size is useful only if:

• Runways can handle the flights
• Gates exist
• Terminals can handle passengers
• Baggage systems can make transfers
• ATC can process the traffic
• Schedules remain reliable

Eventually:

network benefit meets infrastructure constraint.

Frequency Versus Gauge#

Airlines have two broad ways to add seat capacity.

Increase frequency#

Operate:

more flights

Increase gauge#

Operate:

larger aircraft

For example, an airline might choose between:

• Four 100-seat flights
• Two 200-seat flights

Both offer:

400 seats

But they create very different networks.

Why Frequency Matters at a Hub#

More frequency can create:

• More schedule choice
• More possible connections
• Better recovery options
• Greater appeal to business travelers

A larger aircraft can lower unit cost while reducing the number of departure times.

So network planning balances:

frequency + aircraft gauge + total capacity

rather than simply choosing the biggest airplane.

Regional Feed#

Thin markets can be brought into a hub using smaller aircraft.

A regional service might connect:

small city → hub

where passengers transfer to:

• Domestic trunk flights
• Long-haul flights
• Alliance partners

The small market may not support its own nonstop flight to every final destination.

Hub aggregation makes those journeys possible.

Regional Feed Is Not Just "Codeshare"#

In the United States especially, regional feed can involve commercial structures such as:

• Capacity-purchase agreements
• Branded regional operations
• Codeshares

The regional operator may fly an aircraft while the larger airline:

• Controls much of the schedule
• Markets the service
• Bears substantial revenue risk

See Codeshare Flights Explained.

The precise commercial structure is separate from the hub topology.

Route Profitability Versus Network Contribution#

This is one of the deepest concepts in airline economics.

Imagine:

Small City → Hub

The flight itself looks weak.

Perhaps fares on that segment alone do not appear impressive.

But its passengers connect onto:

• Hub → London
• Hub → Tokyo
• Hub → São Paulo

Those later flights generate additional revenue.

So the airline asks not only:

Is this flight profitable by itself?

but also:

What revenue does this flight contribute to the rest of the network?

See How Airlines Make Money.

A Weak Spoke Can Support a Strong Network#

A feeder route might be strategically valuable because it:

• Supplies premium passengers
• Feeds long-haul flying
• Supports corporate contracts
• Strengthens loyalty
• Provides cargo
• Protects market presence

Removing it may damage revenue on several other routes.

That is why route economics inside a hub cannot always be understood in isolation.

Connecting Revenue Does Not Belong Only to Hub Airlines#

A point-to-point carrier can also sell connections.

Southwest is a particularly useful example.

Southwest has historically been associated with point-to-point flying, but its own current filings describe a hybrid network that combines:

• Nonstop point-to-point demand
• Intentional one-stop connectivity
• Many connection points

So: "point-to-point airlines have no connecting revenue"

is false.

Southwest: A Hybrid Example#

Southwest's 2026 annual filing describes its network as blending:

• Point-to-point nonstops
• Intentional connectivity

rather than concentrating almost all transfers through a few mega-hubs.

That means an airport can be an important Southwest connection point without functioning exactly like:

• Atlanta for Delta
• Dallas/Fort Worth for American
• Frankfurt for Lufthansa

Network structures exist on a spectrum.

Ryanair: A More Deliberate Point-to-Point Model#

Ryanair provides a useful contrast.

In its FY2026 filing, Ryanair explicitly describes itself as operating:

short-haul point-to-point routes

and says its point-to-point approach allows it to avoid costs associated with providing through service for connecting passengers, including:

• Baggage transfer
• Transit-passenger assistance

The company operates from many bases rather than funneling most traffic through a small number of connecting hubs.

That is much closer to the pure point-to-point mental model.

A Base Is Not Automatically a Hub#

Ryanair had dozens of operating bases in FY2026.

A base can mean:

• Aircraft are stationed there.
• Crews start/end duty there.
• The airline operates many routes there.

But if the schedule is not designed primarily around coordinated passenger transfers:

the base is not functioning like a traditional connecting hub.

Secondary Airports Are Not the Definition of Point-to-Point#

Ryanair is also famous for using airports such as:

• London Stansted
• Brussels Charleroi
• Paris Beauvais

But Ryanair also serves many primary airports, including:

• Madrid
• Lisbon
• Copenhagen
• Rome Fiumicino
• Milan Malpensa

So:

secondary airport ≠ point-to-point

and:

point-to-point ≠ secondary airport

Airport strategy and network topology are separate choices.

easyJet and Other LCCs#

Low-cost airlines often emphasize direct O&D demand.

But again:

LCC = business model

while:

point-to-point = network topology

An airline can have:

• Low costs and hubs
• High costs and point-to-point routes
• A mixture of both

Do not use the terms interchangeably.

Lufthansa Group Shows Both Models at Once#

The Lufthansa Group provides an unusually clear example.

Its 2025 annual report describes a:

multi-hub strategy

for its Network Airlines.

Its major hubs include:

• Frankfurt
• Munich
• Zurich
• Vienna
• Brussels

At the same time, the Group describes Eurowings as focused on:

point-to-point traffic

in European short- and medium-haul markets.

One airline group therefore deliberately operates both network architectures.

Alliance Feed Extends the Hub#

A hub's network can extend beyond one airline's own aircraft.

Airline alliances, codeshares, interline agreements and joint ventures can bring additional passengers into the hub.

See:

• Airline Alliances Explained
• Codeshare Flights Explained

But:

alliance connectivity ≠ hub connectivity

The hub describes network topology.

The alliance describes airline cooperation.

International Gateway Hubs#

Some hubs specialize heavily in connecting long-haul international flows.

Examples include:

• Dubai
• Doha
• Singapore
• Istanbul

These airports can combine demand from many origins onto long-distance departures that individual city pairs might not support at high frequency.

Local Demand Still Matters#

A hub does not require every passenger to connect.

Major hubs can also have enormous local O&D demand.

For example:

• London
• Paris
• New York
• Tokyo

serve huge metropolitan markets while also carrying substantial connecting traffic.

A hub can be both:

a destination

and:

a transfer point.

Atlanta as a Current Example#

Atlanta remains a particularly powerful U.S. hub example.

ACI's final 2025 data ranked Hartsfield-Jackson Atlanta International Airport:

#1 in the world for total passenger traffic

with about:

106.3 million passengers

in 2025.

That should not be confused with aircraft movements.

In the same ACI dataset:

Chicago O'Hare ranked #1 in aircraft movements

while Atlanta ranked second.

"Busiest airport" therefore requires a metric.

Hub Capacity Is Not Infinite#

A successful hub can run into constraints such as:

• Runway capacity
• Gate availability
• Taxiway congestion
• Terminal capacity
• Baggage capacity
• Airspace capacity
• Airport slots
• Curfews

See Airport Operations 101.

A network cannot schedule unlimited connecting banks simply because the demand exists.

Airport Slots Can Reinforce a Hub#

At capacity-constrained airports, an airport slot can become strategically valuable.

An incumbent hub carrier with many well-timed slots can create:

• High frequency
• Dense connection banks
• Strong corporate schedules
• Large partner networks

Scarce slots can therefore reinforce the competitive strength of an established hub.

Hubs and Baggage#

A hub is also a baggage-transfer machine.

A connecting passenger's bag may need to move:

inbound aircraft → sortation → transfer system → outbound aircraft

within the available connection window.

See How Baggage Handling Works.

Passenger Connection Time Is Not the Whole Story#

A passenger can run to the next gate.

Their checked bag must also:

• Be unloaded
• Scanned
• Sorted
• Transported
• Loaded

A very tight connection can therefore create:

• Passenger misconnect
• Bag misconnect
• Or both

Hub schedules must account for both.

Why Hub Disruptions Can Be So Painful#

A hub concentrates:

• Flights
• Aircraft
• Crews
• Passengers
• Bags

into one place.

That produces extraordinary connectivity when the system works.

It also creates concentration risk.

Bank Disruption#

Suppose thunderstorms reduce the hub's arrival capacity.

Inbound aircraft can be:

• Delayed at origin
• Held
• Rerouted
• Diverted

Passengers then miss the departure bank.

The outbound flights may:

• Wait
• Depart without connectors
• Become delayed themselves

Reactionary Delay#

An aircraft delayed into the hub may operate another flight later.

The delay can therefore move through its aircraft rotation.

The same happens with:

• Crew
• Passengers
• Bags

See Flight Delays & Cancellations Explained.

Point-to-Point Networks Also Propagate Delays#

The common claim: "A point-to-point delay affects only one flight"

is false.

Imagine one aircraft operates:

A → B → C → D → E

Even if nobody connects:

• A delay on A → B
• Delays the aircraft into B
• Which delays B → C
• Which can delay C → D

Aircraft rotation alone propagates disruption.

Crew rotations can do the same.

What Hubs Add to the Propagation Problem#

The hub creates additional dependencies.

Besides the aircraft and crew:

• Hundreds of connecting passengers may depend on the flight.
• Transfer bags depend on it.
• The next bank depends on coordinated timing.

So hubs can amplify disruption through more interconnected resources.

But point-to-point networks are not dependency-free.

Utilization Versus Resilience#

Point-to-point airlines often value:

• Fast aircraft turnarounds
• High aircraft utilization

because aircraft generate revenue while flying rather than sitting unnecessarily on the ground.

But very tight scheduling reduces recovery margin.

This produces the same tradeoff we saw in How Airlines Make Money:

higher utilization ↔ lower schedule slack

Hubs Can Also Improve Recovery#

Hubs create vulnerabilities, but they can create recovery options too.

A large hub may have:

• More flights to the destination
• More spare crews
• Maintenance capability
• More aircraft
• Alliance alternatives
• Better passenger-service resources

A cancelled flight at a hub might have several replacement options.

A thin point-to-point route operating twice weekly may have almost none.

So resilience is not simply:

point-to-point good, hub bad.

Passenger Experience: Nonstop Versus Connection#

Passengers usually value:

• Less travel time
• Fewer transfers
• Lower misconnection risk

So when two products are otherwise comparable:

nonstop service is often attractive.

But the comparison is rarely equal.

A hub can provide access where a nonstop simply does not exist.

Why Thin Markets Need Connections#

Suppose only:

20 passengers per day

want to travel from City A to City Z.

That may not justify an aircraft.

But perhaps:

• 20 want A → Z
• 30 want B → Z
• 25 want C → Z
• 40 want D → Z

A hub can aggregate those passengers onto one:

Hub → Z

departure.

The hub creates a viable flight from many individually thin markets.

A Nonstop Can Bypass the Hub When Demand Grows#

If City A → City Z demand eventually becomes large enough:

the airline can launch:

A → Z nonstop

That is called hub bypass in a broad network sense.

Airlines continually evaluate whether aggregated connecting demand has become strong enough to support a direct market.

Longer-Range Aircraft Change That Threshold#

Aircraft technology can make thinner nonstop routes viable.

Examples include:

• Boeing 787
• Airbus A321XLR

Their economics allow airlines to consider routes that might previously have required:

• Larger aircraft
• Hub aggregation
• A connection

This does not eliminate hubs.

It changes the demand threshold at which bypass becomes practical.

The A321XLR Makes This Visible Today#

Long-range narrowbody flying is no longer theoretical.

By 2026, airlines are using the A321XLR on long-haul markets that combine:

• Narrowbody capacity
• Intercontinental range

This gives network planners another tool for serving "long, thin" markets directly.

But the same aircraft can also operate:

hub → thin destination

So aircraft technology benefits both network models.

Cargo Can Strengthen Hub Economics#

Passenger hubs can also aggregate:

belly cargo.

Cargo moving:

Origin A → Hub → Destination B

can add revenue to flights that are already carrying passengers.

For some long-haul routes, cargo materially improves the network contribution.

The economics therefore go beyond seat demand alone.

Hub-and-Spoke Advantages#

1. Demand aggregation#

Thin passenger markets can be combined.

2. Large network reach#

A relatively limited set of physical links can create many one-stop markets.

3. Frequency#

Aggregated demand can support frequent hub-spoke flights.

4. Long-haul feed#

Many short-haul origins can support one long-haul departure.

5. Network economics#

A route can contribute revenue to many other flights.

6. Centralized capabilities#

Hubs can concentrate:

• Maintenance
• Crew
• Ground handling
• Lounges
• Operations control

Hub-and-Spoke Disadvantages#

1. Passenger travel time#

A connection usually takes longer than an available nonstop.

2. Misconnection risk#

Passengers and bags depend on both flights operating properly.

3. Infrastructure peaks#

Banks can overload:

• Runways
• Gates
• Security
• Baggage
• Staffing

4. Disruption concentration#

Weather at one airport can affect a large share of the network.

5. Complex optimization#

Changing one flight can affect dozens of connection markets.

Point-to-Point Advantages#

1. Strong nonstop product#

Routes can directly serve O&D demand.

2. Lower connection dependency#

Fewer passengers may depend on synchronized transfer banks.

3. Schedule flexibility#

Routes do not always need to align around a few hub waves.

4. Fast turns#

Some point-to-point business models emphasize short ground time.

5. Easier market entry and exit#

Capacity can potentially be moved among independent O&D markets more easily.

Point-to-Point Disadvantages#

1. Thin markets are difficult#

Demand must justify the route more directly.

2. Less aggregation#

A flight cannot rely as heavily on traffic collected from dozens of feeder markets.

3. Network reach can be sparse#

The airline may serve many airports without offering useful service between every pair.

4. Recovery options can be limited#

Low-frequency routes can leave passengers with few alternatives after cancellation.

Business Model Is Not Network Model#

This distinction is worth repeating.

Network carrier#

Often uses:

• Hubs
• Connections
• Regional feed
• Premium products

Low-cost carrier#

Often emphasizes:

• Direct O&D demand
• Fast turns
• Simpler fleets

But these are tendencies.

They are not definitions.

A low-cost airline can develop connection flows.

A network carrier can fly many point-to-point nonstops.

Hybrid Networks Are Normal#

Modern airlines increasingly combine several approaches.

A carrier might operate:

• Highly banked primary hub
• Smaller rolling hub
• Focus cities
• Secondary-city nonstops
• Alliance feed
• Regional feed

all inside one network.

The important question is:

What role does each route play?

Real-World Spectrum#

Ryanair#

Strongly point-to-point.

Its FY2026 filing explicitly describes frequent short-haul point-to-point service and avoiding through-service costs for connecting passengers.

Southwest#

Hybrid.

Its current filings describe a network combining point-to-point nonstops with intentional one-stop connectivity across many connection points.

Lufthansa Group#

Both.

Its Network Airlines use a multi-hub strategy while Eurowings is organized around point-to-point traffic.

Emirates#

Highly hub-oriented.

Dubai aggregates traffic between many international markets.

Qatar Airways#

Highly hub-oriented around Doha.

These are not perfectly pure categories.

They are positions on a spectrum.

Why "Which Model Is Better?" Is the Wrong Question#

The right model depends on:

• O&D demand
• Geography
• Airport capacity
• Fleet
• Labor
• Slots
• Competition
• Fare levels
• Passenger preferences
• Cargo
• Partnerships

A hub can be brilliant in one market and wasteful in another.

A point-to-point route can be highly profitable where local demand is dense and impossible where it is thin.

Common Myths About Airline Networks#

Myth: Point-to-point means every passenger flies nonstop#

No.

Point-to-point is a network design concept.

Point-to-point airlines can still sell connections.

Myth: Point-to-point airlines have no connection points#

No.

Southwest currently describes more deliberate connectivity through core stations while still retaining a point-to-point-oriented network.

Myth: Southwest is a pure point-to-point airline#

Not anymore as a complete description.

Southwest itself describes its current strategy as a blend of point-to-point nonstop demand and intentional one-stop connectivity.

Myth: Ryanair only flies to secondary airports#

No.

Ryanair uses many secondary airports but also operates at major primary airports.

Myth: Low-cost carrier means point-to-point#

No.

One describes a business/cost model.

The other describes network topology.

Myth: Hub-and-spoke means every passenger connects#

No.

Hub flights also carry local O&D passengers.

Myth: A hub airport is just an airline's biggest airport#

Not necessarily.

A hub's defining strategic role is connecting traffic.

Myth: A crew base is automatically a hub#

No.

Crew placement and passenger-network topology are different decisions.

Myth: A point-to-point delay affects only one flight#

No.

Aircraft and crew rotations can propagate delays even without passenger connections.

Myth: Hubs are always less reliable#

No.

Hubs create more dependencies but can also provide more recovery resources and alternative flights.

Myth: Point-to-point is always cheaper#

No.

Cost depends on aircraft, airport, labor, utilization, demand, stage length and many other factors.

Myth: Hub flights always have higher fares#

No.

Pricing depends on competition and demand, not network topology alone.

Myth: High passenger load factor proves the network is profitable#

No.

Passenger load factor measures how much capacity was used.

Profitability also depends on:

• Yield
• Unit revenue
• Unit cost
• Cargo
• Ancillaries
• Network contribution

Do not confuse passenger load factor with the aerodynamic load-factor concept.

Myth: Large aircraft are always better for hubs#

No.

Large aircraft reduce unit costs when demand supports them.

Smaller aircraft can create more frequency and serve thinner spokes.

Myth: Every hub should be tightly banked#

No.

Banking creates more connections but also more congestion and peak-resource demand.

Myth: A route that loses money by itself should be cancelled#

Not automatically.

Its feeder traffic can create valuable revenue elsewhere in the network.

Myth: Longer-range aircraft will eliminate hubs#

No.

They make some hub-bypass routes viable but also make new hub-to-thin-market routes viable.

Myth: Nonstop flying is always more environmentally efficient#

Not necessarily.

A nonstop avoids connection detours, but actual per-passenger emissions depend on:

• Aircraft
• Distance
• Load factor
• Payload
• Route
• Network design

The comparison must be made for the actual alternatives.
