243 seats: 21 good, 18 mixed, 11 to avoid

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 17, seats A, B, C, D, E and F (Economy): row in front of the overwing exits: recline is likely limited (Frontier's map doesn't say), with no exit-row legroom of its own.
Row 28, seats A, B, C, D and E (Economy): row in front of the mid-cabin exit door: recline is likely limited (Frontier's map doesn't say).

166 seats: 9 good, 14 mixed, 12 to avoid

Row 1, seat A (Falcon Gold): front Falcon Gold flat bed at the window.
Row 4, seat D (Falcon Gold): falcon Gold flat bed at the back of the small cabin, away from the front galley and toilet.
Row 8, seat A (Economy): first Economy row, behind the Falcon Gold cabin, with no one in front.
Row 16, seats A, B, D, E and F (Economy): exit row with extra legroom

Row 14, seats A, B, D, E and F (Economy): in front of an exit row, so recline is likely limited
Row 14, seat C (Economy): in front of the overwing exits, so recline is likely limited.
Row 33, seat A (Economy): last row, against the rear toilets.
Row 33, seats B, C, D and E (Economy): next to a lavatory, with queues, noise and flushing
