Frequent flyer programs are, for the most part, pretty straight-forward. The same can be said about hotel loyalty programs. With frequent flyer programs, the more you fly, the more miles you earn. For hotel loyalty programs, the more nights you stay with a hotel chain, the more points you earn. Finally, for credit cards, the more you spend, the more you earn. However, this only scratches the surface. Frequent flyers have created an entire community based on earning points, miles, and status. That community has also unintentionally created their own lingo. If you’re looking to get started with travel rewards programs or aren’t quite sure that a word or term means, here’s the frequent flyer’s dictionary.

With so many terms, phrases, and words related to frequent flyer and travel rewards programs, this post will occasionally be updated. Frequent flyers and readers looking to contribute new terms and phrases can comment at the end of this post or by sending us an email at

The words, phrases, and terms included in this post are defined in the context of frequent flyer and travel loyalty programs.

For travelers just starting out with loyalty programs, frequent flyer jargon can be somewhat intimidating. However, using the frequent flyer’s dictionary above, anyone can master frequent flyer and travel loyalty programs in no time.
