307 seats: 18 good, 28 mixed, 11 to avoid

Rows 1–5, seats D and G (Business): one of the centre pair, each with its own aisle: good for two travelling together, with nobody to step over.
Rows 9 and 30, seats A, C, H and K (Economy): exit row by the door, sold as an Extra Legroom seat: open floor in front, but people pass on their way to the lavatories and galley. No children under 14 or people with reduced mobility.

Row 28, seats D, E, F and G (Economy): backs onto the lavatories or galley Aer Lingus draws behind this row: recline is likely limited, and the queue forms beside you.
Rows 42–44, seat E (Economy): middle of the three centre seats where the cabin narrows: a neighbour on each side and no aisle of your own.
Row 44, seats A, C, H and K (Economy): last row of the cabin, with lavatories or a galley drawn right behind it: recline is likely limited and there is traffic and noise.

296 seats: 3 good, 18 mixed, 9 to avoid

Row 47, seats A, C, E, F, G, H and K (Economy Class): next to a lavatory, with queues, noise and flushing
Row 47, seat D (Economy Class): in front of the mid-cabin lavatories.
Row 63, seat A (Economy Class): last full side row, by the rear lavatories.
