The Boeing 737-800’s seating is made up of 16 First Class seats in rows of two, 48 Economy Plus seats in rows of three and 90 Economy seats in rows of three. The First Class seats are 21 inches wide and recline up to 7.5 inches; the Economy Plus seats are 17.3 inches wide and recline up to 5 inches; and the Economy seats are 17.3 inches wide, reclining up to 3 inches.

While these features apply to the Boeing 737-800 standard model used by some airlines, the number and types of seats are designed according to the requirements of each specific airline employing the aircraft. Certain flight routes that are highly frequented by economy travelers employ aircraft with a smaller number of First and Economy Plus seating to increase Economy seating.
