A fare class is a booking category that can affect price, flexibility, mileage credit and upgrade eligibility, even inside the same cabin.

The FlyAndCry definition
A secret letter explaining why the identical seat beside you cost less.
Equality at 35,000 feet
Everyone receives the same oxygen. Everything else has been alphabetised by revenue.
Your fare class may be called K, Q or V because “You paid too early and still paid too much” would not fit in the reservation system.
Common symptoms
- Your ticket looks flexible until it meets a calendar.
- Your miles earn fewer miles than expected.
- An upgrade is available to a letter you are not.
At FlyAndCry
We offer 47 fare classes in one cabin. The seat is identical; the regret is dynamically priced.
