Row 1, seats A and C (UpFront Plus): upFront Plus front row: extra legroom, the middle seat kept empty and nobody reclining into you, though the forward lavatory is just ahead on this side. Frontier offers no seatbelt extensions in row 1 and doesn't seat infants there.
Row 1, seats D and F (UpFront Plus): upFront Plus front row: extra legroom, the middle seat kept empty and nobody reclining into you; the block ahead on this side is likely the galley. Frontier offers no seatbelt extensions in row 1 and doesn't seat infants there.
Row 2, seats A, C, D and F (UpFront Plus): upFront Plus: extra legroom near the front, and Frontier guarantees the middle seat beside you stays empty.
Row 3, seats A, C, D and F (Economy): premium row right behind UpFront Plus: extra legroom close to the front, without the UpFront Plus price.

Row 41, seats A, B, C, D, E and F (Economy): last row of the aircraft, right against the rear lavatories: recline is likely limited and the lavatory queue forms by your seat.
