First class (aviation)
First class, sometimes called A1, is a luxury travel class on some airliners that exceeds "Business Class", "Premium Economy Class" and "Economy Class". On a passenger jetliner first class refers to a limited number (rarely more than 16) of seats or cabins located in the front of the aircraft which are notable for their comfort, service and privacy. Propeller airliners occasionally have first class in the rear.
