The seating arrangements on the United Airlines Domestic Fleet are established for all three classes - First, Economy Plus and Economy.
The quantity of seats in a particular class on an aircraft are related to the pitch of those particular seats in a particular class. For example a seat found in First Class may have a pitch (or lean back) of 38 inches while a seat in Economy class may have a pitch of only 31 inches.
This basically means that the greater the pitch the greater amount of leg room for the passengers behind. Therefore travelling First class will allow a passenger to stretch out more than an Economy passenger.
There are currently five different aircraft types used by United Airlines which form their domestic fleet - Airbus A319 and A320; and Boeing 737-300, 757-200 and 777-200 (United's low-price domestic carrier called TED also operates the Airbus A320).
