Budget Airline Fees: What the Cheap Fare Really Costs

A low cost airline is not a cheaper version of a full service airline. It is a different business model that sells the seat at close to cost and earns the margin from everything around it. The fare is real and the flight is real, and the total cost of the trip depends on how many of the ancillary products the traveller needs. Compare the total, not the fare.

Budget Airline Fees: What the Cheap Fare Really Costs: questions people actually ask

Why are budget airline fees so high?

Because the business model sells the seat at close to cost and earns the margin from the extras. Bags, seats and priority boarding are priced high relative to their cost because the traveller who needs them has already committed to the flight. Buying them at booking time is much cheaper than at the airport.

Is it cheaper to pay for a bag online or at the airport?

Online, at the time of booking, is almost always cheapest. Airport and gate baggage fees are the highest in the structure and are charged per bag, so weighing and measuring the bag at home and paying for it in advance is the single most effective way to control the total cost.

Do budget airlines charge for checking in at the airport?

Some do, and online check in is free. The fee exists to move travellers to the app and reduce desk staffing. Travellers who need document verification, for example for a visa, may be required to use the desk, and should check whether the fee applies in that case.

Is a budget airline actually cheaper than a full service carrier?

For a traveller with a personal item only, no seat preference and a fixed date, frequently yes. For a traveller with a checked bag, a chosen seat and a possible change, the total is often similar or higher, and the comparison should be made on the total including the airport transfer and the schedule. One more rule of thumb is worth keeping: if the total after the bag and the seat is within a small margin of a full service fare, buy the full service fare. The reason is not comfort but the failure cost. A full service ticket usually carries a change option, a real schedule and a partner network for rebooking, and those three things are worth more on the day something goes wrong than the small saving they cost today. The low cost model wins when the trip is simple and the traveller is disciplined, and it loses in exactly the situations where a traveller needs help. The comparison takes ten minutes and it is the only one that answers the question the fare appears to ask.

The business model behind the cheap seat

A low cost carrier reduces the cost of producing a seat by flying one aircraft type, turning the aircraft quickly, using secondary airports with lower charges and selling most tickets directly. The seat is then priced low to fill the aircraft, and the margin comes from ancillary revenue: bags, seats, priority boarding, food and changes.

That is why the ancillary prices are set high relative to their cost. A checked bag that costs the airline a small amount to handle is sold for a multiple of that, because the traveller who needs the bag has already chosen the flight. The airline is not being deceptive; it is monetising the parts of the journey that a full service carrier bundles into the fare.

The model has a real advantage for the traveller who matches it: a person with a small personal item, no seat preference and a fixed plan genuinely flies for less than on a legacy carrier. The model punishes the traveller who buys the extras late, because the prices rise through the journey from booking to the gate.

Understanding the model is the whole game. A traveller who prices the trip as the airline prices it, with every extra decided at booking time, gets a low total. A traveller who discovers the extras at the airport pays the highest prices in the system for the same journey.

Baggage: the largest and most variable fee

Baggage on a low cost carrier is usually sold in tiers: a personal item included, a cabin bag for a fee, a checked bag for a larger fee, and combinations. The price depends on the route, the season and the point of purchase, and the same bag can cost several times more at the airport than online.

The size rules are enforced by measurement at the gate, and the measurement is strict. A bag that is a centimetre over can be charged at the gate rate, and the gate rate is the highest in the structure. The traveller should measure the bag against the specific airline’s published dimensions rather than against a memory of another airline.

The weight rules matter for checked bags and are enforced at the desk. A bag that is over the purchased weight is charged per kilogram or per excess unit, and the charge is applied at the airport rather than at booking. A luggage scale at home is the cheapest tool in low cost travel.

The tiering also creates a comparison problem. A fare that includes a cabin bag is not comparable with a fare that does not, and the two are often shown side by side on a comparison site with the same price displayed. The traveller must open the fare conditions and price the bag before concluding that one is cheaper.

Seats, check in and boarding

Seat selection is a fee on most low cost carriers and free only when the airline assigns a seat at check in. The fee range is wide: a standard seat in the middle of the cabin is cheap, an exit row or a seat at the front is expensive, and the price rises as the flight fills. A traveller who does not care about the seat pays nothing and takes what is left.

The exception is a traveller who needs to sit with someone, particularly with a child. Many airlines have a policy that guarantees children sit with an adult, but the policy and the definition of a child vary, and the traveller should check the specific rule rather than assume the seats will be together.

Airport check in is a fee on some carriers, and online check in is free. The fee exists to move travellers to the app and to reduce staffing, and the traveller who has not checked in online pays for the privilege of a desk. The exception is a traveller with a document that must be verified, such as a visa, who may be required to use the desk.

Boarding order is sold as priority and is worth something on a full flight. A traveller who boards last may find no space for the cabin bag in the overhead bin, and the bag is then checked at the gate, sometimes for a fee. Priority boarding is therefore a baggage product for travellers with a cabin bag on a full flight, which is not how it is marketed.

Payment, changes and the small print

Some low cost carriers charge a booking fee that depends on the payment method, and a card fee is applied per booking or per passenger. A traveller can sometimes avoid it by using a payment method the airline does not surcharge, and the saving is small but free. The fee should be included in the total comparison.

Change fees on low cost carriers are frequently the price of the new fare plus a change fee, and the original fare is not credited in full on the cheapest tickets. A traveller who might need to move a date should price a flexible product on the same airline or a standard fare on a full service carrier before assuming the cheap fare is cheap.

Cancellation is usually impossible on the cheapest fares, and the taxes may be refundable while the fare is not. The traveller who is unsure of the plan should read the cancellation rule rather than the headline price, because a ticket that cannot be cancelled has no value in a plan that might change.

The small print also covers schedule changes. Low cost carriers operate thinner schedules than legacy carriers on many routes, and a schedule change can move a flight by hours or to a different day. The airline will normally offer a refund or a rebooking, but the alternatives on a thin route may be a day later, which is a real cost to a traveller with a fixed plan.

How to compare totals honestly

The method is to price the trip as it will be taken. Add the bag, the seat if it matters, the check in if the airline charges for the desk, and the payment fee. The result is the comparable total, and it can be compared with a full service fare that includes the same items.

The second step is to compare the airports. A low cost carrier often uses a secondary airport, and the transfer to the city can cost more than the difference in fare. The total journey cost includes the transfer on both ends, and the comparison should include it.

The third step is to compare the schedule. A flight at six in the morning that requires a taxi because the trains have not started, or a flight that arrives after the last connection, has a cost that the fare does not show. The traveller should price the ground arrangements for each option.

The fourth step is to compare the risk. A thin schedule, a non changeable ticket and a secondary airport together produce a trip that is expensive to fix if anything goes wrong. For a trip with a fixed commitment at the destination, the cheaper option can be the wrong one, and the comparison should include the cost of a failure.

A decision routine for the next low cost trip

Before booking, decide what the trip needs: a bag, a seat, a flexible date or none of them. Then price those extras at the same time as the fare, using the airline’s own site rather than a comparison site that hides them. The total at that point is the real price of the trip.

Then compare that total with the alternatives on the same route, including the full service carriers, and include the airport transfer and the schedule in the comparison. The cheapest total is the one to buy, and it is frequently not the cheapest fare.

Then buy everything at once. A bag bought at the time of booking costs the least, and a seat bought at the same time is cheaper than one bought later. The traveller who completes the purchase with all the extras included has locked the total and removed the airport surprises.

Finally, pack to the allowance that was purchased rather than the one that was imagined. The bag that is measured at home and weighed at home is the bag that boards without a fee, and the discipline of packing to a limit is the habit that makes the low cost model work in the traveller’s favour instead of the airline’s.
