# What is Mile?

A mile is the currency unit of a frequent flyer programme: a credit in an airline account that can be exchanged for flights and other awards.

Also called: Airline mile, Frequent flyer mile.

## How it works #

A mile long ago stopped corresponding to distance flown; most programmes now credit it against ticket price or card spending. It is not money: the issuer alone decides what it buys, can reduce that at any time and owes the holder nothing. Treating miles like cash and stockpiling them means carrying that risk for no return.

## Not to be confused with #

A mile is not the same as a transferable bank point: the mile sits with exactly one airline, while the bank point still has several possible destinations.

## In German #

The German term is Meile. [German version of this term](/de/glossar/meile)
