Frontier Airlines Airbus A321neo seat map
Frontier's own seat map for the Airbus A321neo shows 243 seats, all 3-3: 12 in UpFront Plus (rows 1 and 2) and 231 in Economy. UpFront Plus has extra legroom and Frontier keeps its middle seats (B and E) empty, so only 8 are sold. Economy runs from row 3 to 41, with exit rows 18, 19, 29 and 30. Frontier's legend: UpFront Plus rows 1-2, Premium rows 3, 18, 19, 29 and 30A, Preferred rows 4-17, Standard all other rows, Exit Row Premium rows 18-19, 29 and 30A, Exit Row Standard 30B-C; Premium seats have extra legroom, Preferred seats are simply closer to the front. A lavatory is at the front, and the rear lavatories are behind the last row. Frontier gives seat widths of 16.5 to 19.1 inches on this aircraft family but no pitch. It is adding a 2-2 First Class at the front as aircraft are refitted, which this A321 (240 seats) drawing predates. Frontier titles the drawing 240 seats, but it draws 243 seat boxes; the drawing is followed.
