What is a frequent flyer number?

A frequent flyer number is a unique identifier assigned to a traveler who participates in a loyalty program offered by an airline or group of airlines. By providing this number when booking flights or checking in, travelers can earn miles or points for their travel, which can be redeemed for rewards such as free flights, upgrades, or other perks.

Frequent flyer numbers are typically associated with specific airlines or airline alliances, such as Star Alliance, OneWorld, or SkyTeam, and can be used across multiple airlines within the same alliance. Travelers may also earn miles or points through partner airlines, hotels, car rental companies, credit cards, or other participating businesses.

Frequent flyer numbers are important for tracking and managing a traveler's loyalty program account, as well as for ensuring that miles or points are properly credited for each flight. It is recommended that travelers keep their frequent flyer number handy and provide it whenever they book flights or travel, in order to maximize their rewards and benefits.
