An airplane seat option consists of an AISLE (5 letters), armrest (7 letters), STRAP (5 letters), armrests (8 letters), and trays (5 letters). An AISLE is a passageway between rows of seats, while an armrest is a support for the arms. A STRAP is a piece of material used to secure a person in their seat, while armrests are two supports for the arms. Lastly, trays are small tables that fold out from the back of the seat in front of the passenger.
