aircoach

noun

1. An airliner offering relatively cheap but cramped passenger flights.

   “Aircoaches are big money-makers for the five or six airlines that use them. They do a near-capacity business on midnight runs for passengers who don't mind the night-flying and who like the lower prices.”

   “Does Eastern Airlines, for instance, put the same number of seats in their aircoaches that you do, in the same type aircraft?”
