What is a frequent-flyer program?

A frequent-flyer program is an airline loyalty program. Members can earn miles or points from flights, credit cards, shopping partners, and transfers from other rewards programs. Those miles may be redeemed for flights and other rewards.

The word “mile” is just a currency name. One mile does not equal one mile of travel, and currencies from different airlines are not interchangeable.

How award tickets work

An award ticket is a flight booked with miles or points, usually plus taxes and sometimes carrier-imposed fees. Programs may use fixed award charts, prices that change with demand, or a combination of both.

Having enough miles does not guarantee a seat. Airlines control which flights are available as awards, and the seats offered to the airline’s own members may differ from those offered to partner programs.

Airline partners and alliances

Many airlines cooperate through alliances or individual partnerships. This can let you use miles from one program to book a flight operated by another airline. For example, the program you book through, the airline operating the flight, and the airline name on the ticket can all be different.

Partner awards can create useful options, but each loyalty program sets its own mileage price, fees, change rules, and access to seats. Always search through the program whose miles you intend to use.

A simple example

You want a flight operated by Airline A. Airline A has no useful award price for its own members, but a partner program can see the same flight for fewer miles. If that partner accepts your transferable points, you may be able to transfer and book there instead.

Common limitations

  • Award prices and availability can change at any time
  • Taxes and fees can make an award poor value
  • Miles may expire under a program’s activity rules
  • Programs can change redemption rates or partner access
  • Changes and cancellations may carry restrictions or fees

A better way to compare awards

Start with the trip, not the currency. Compare the cash fare with the complete award cost, including taxes and fees. Then consider schedule, cancellation terms, transfer time, and how else you could use the points.
