Vols Navette vs Compagnies Low-Cost : Comparaison des Coûts

Defining the Market Segments

Commuter flights — short-haul services operated by regional turboprop or small regional jet aircraft on routes between smaller cities and major hubs — occupy a fundamentally different market position than low-cost carrier services. Commuter routes serve markets that are too thin to support a full-size narrow-body aircraft but where some air service demand exists: routes like London to Newquay, Edinburgh to Stornoway, Chicago to Moline, or Sydney to Dubbo. Budget airlines, by contrast, operate where demand is sufficient for a full-size aircraft and where competitive price pressure is present.

The economics of these two segments diverge sharply. A commuter aircraft like the ATR 72 or Bombardier Q400 carries 50–70 passengers, has higher operating costs per seat-kilometre than a Boeing 737, and typically serves thinner routes where competition is limited or absent. This translates into higher fares per mile than comparable budget airline routes. A 45-minute hop from London to Newquay on Flybe (when it operated) or similar might cost £80–£120 one-way; a two-hour Ryanair flight to Barcelona might cost £20–£40 one-way, despite being four times longer.

The comparison becomes meaningful for travellers who must choose between a short commuter flight to reach a hub airport followed by a budget long-haul flight versus a direct commuter route to their destination. Whether the commuter-plus-LCC combination beats a direct commuter fare depends on distance, connectivity, and your personal value of time.

Cost Per Mile: Commuter vs LCC

Cost per mile (or per kilometre) is the most useful normalised metric for comparing air travel across different route lengths. UK domestic commuter routes consistently show costs of 30–60 pence per mile one-way at standard booking windows. US regional routes on regional carriers operated under major airline codes (American Eagle, Delta Connection, United Express) typically cost $0.40–$0.70 per mile one-way at standard fares.

Budget airline costs per mile are typically 5–15 pence per mile for European routes booked at advance prices. A Ryanair fare of £20 for a 1,000-mile route works out to 2 pence per mile — an order of magnitude cheaper than the commuter equivalent. Even at a "normal" Ryanair fare of £60 for the same route, the cost per mile is 6 pence versus 35–50 pence for a comparable commuter route.

The gap narrows when budget airline fees are added. Adding a £20 checked bag fee, a £10 seat selection fee, and an airport transfer from a secondary airport (£20 each way) to a Ryanair fare increases the effective cost per mile substantially on a short route. On longer routes (over 1,000 miles), the fixed costs of ancillaries are amortised over more miles and the budget airline retains a larger cost advantage. For short routes under 300 miles, the total cost of a commuter flight can be competitive with a budget airline when all fees and transfer costs are included.

Time Cost: The Hidden Variable

Airlines do not charge for your time, but your time has value. A commuter flight from a city-centre airport to a nearby regional hub (typically 30–60 minutes flight time, 15 minutes airport process each end) may provide a total door-to-door journey time of 90–120 minutes for a trip covering 150–300 miles. The same distance by budget airline might require a 45-minute drive or train to a secondary airport, a 45-minute security and boarding process, a 45-minute flight, and a 45-minute transfer at the destination — three and a half to four hours total.

This differential is most pronounced on routes served by both commuter and budget options. Manchester to Amsterdam, for example: a direct Flybe or British Airways CityFlyer flight from Manchester Airport takes 75 minutes door-to-door from city centre; a Ryanair flight from Liverpool (John Lennon Airport, 30 miles south) to Amsterdam Eindhoven (60 km south of Amsterdam city centre) takes three hours total including surface transfers. The Ryanair option might save £30–£50 in airfare, but at the cost of 90 additional minutes of travel time. At an implicit hourly value of £25–£30, the commuter flight is the rational choice for time-sensitive travellers.

For leisure travellers with elastic schedules and a clear priority on minimising cash expenditure, budget airline routes via secondary airports make economic sense even when the total travel time is longer. A retired couple travelling from the English Midlands to the Spanish coast, who will not be charged overtime for extra travel time and who pack light, save real money choosing Ryanair from East Midlands over a British Airways feeder-to-hub option.

Regional Air Service: When There Is No LCC Alternative

In many regional markets, no budget airline competition exists because the route is too thin to support a full-size aircraft. Scotland's Highlands and Islands, the Norwegian fjords, Alaska's rural communities, and remote Australian Outback towns are served exclusively by regional turboprop operators — Loganair, Wideroe, Alaska Airlines' regional feeders, and Rex respectively. On these routes, the commuter fare is not competing with an LCC; it is competing with a 10-hour drive, a ferry crossing, or no trip at all.

Essential air service designations in the US (supported by EAS subsidies), similar obligations in the EU, and PBO agreements in Australia ensure that these routes receive some level of service at fares capped by regulation or subsidy. The result is that on truly remote routes, the commuter fare is often the only realistic option and the price, while high per mile, represents genuine value for access to otherwise unreachable communities.

Frequent flyers on subsidised regional routes should investigate whether full-service carrier loyalty programmes extend to their regional partner. Delta Connection, American Eagle, and United Express all earn full-service miles on operated flights, meaning a weekly commuter trip from a regional city to a hub can generate significant loyalty currency. Loganair has codeshare arrangements with British Airways, Flybe (when operational), and others, enabling earn on the regional segment.

When to Mix Commuter and Budget Carriers

The most economical option on many multi-leg international trips is a commuter flight from a small regional airport to a gateway hub, followed by a budget or full-service transatlantic or transpacific flight. This combination is particularly relevant for travellers from smaller European cities who want to access Ryanair's or easyJet's extensive pan-European network from London, Dublin, or Amsterdam hubs.

The risk of mixing carriers on self-booked itineraries is the missed connection. A commuter flight delayed 90 minutes (not uncommon on weather-sensitive turboprop routes) will cause you to miss a separately booked Ryanair flight with no obligation on Ryanair's part to rebook you. Build in a minimum of three hours between a commuter arrival and a budget airline departure when creating self-transfer itineraries. On Kiwi.com's self-transfer engine, a "Nomad" booking adds its own rebooking guarantee but at a cost that may reduce the fare advantage.

For business travellers who must reach smaller cities that have commuter service but no direct budget airline service, the question is often whether to route via a hub with a commuter feeder (more reliable, may earn full-service miles, but more expensive) or drive to a larger airport and take a budget airline (cheaper, more flight options, but longer total journey and no luxury of earning miles). There is no universal answer — it depends on the specific origin–destination pair, the cost of your time, and whether a checked bag is required.
