Frontier Seating Chart
Frontier flies an all-Airbus fleet in a single Economy cabin: 186 seats on the A320 and A320neo, 230 on the A321ceo and 240 on the A321neo. No seat on any of them reclines, and there is no WiFi, no power and no seatback screen anywhere in the fleet.
What the Seat Letters Mean
Frontier uses the standard Airbus 3-3 lettering on every aircraft: A, B and C on the left of the aisle and D, E and F on the right. A and F are windows, C and D are aisles, B and E are middles. Seats 31A and 31F on the A320 are lettered as windows but have blank wall instead.
UpFront Plus and Stretch Are Not the Same Product
UpFront Plus is rows 1 to 3 with the middle seat blocked, at 32 inches of pitch — you are buying width. Stretch is the exit rows at 35 inches — you are buying legroom. Tall passengers want Stretch. On the A320 the best seats are 13A and 13F; on the A321neo it is row 19.
