174 seats: 6 good, 7 mixed, 14 to avoid

Row 1, seat F (Business Class): front row of Business, first off the aircraft.
Row 11, seats B and E (Economy Class): likely an overwing exit row: Finnair draws the wing here and marks the row Extra leg room, but doesn't label the exits
Row 11, seat C (Economy Class): extra leg room on the aisle, just behind the Business divider.
Row 11, seat D (Economy Class): extra leg room on the aisle, and it reclines.

Row 10, seat A (Business Class): last Business row at the window: Finnair marks it No recline.
Row 10, seat F (Business Class): finnair's map marks this a No recline seat

186 seats: 16 good, 16 mixed, 6 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 11, 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.
