265 seats: 9 good, 18 mixed, 39 to avoid

Row 1, seat D (Business Class): front-row Business seat in the middle pair, away from the aisle traffic of the later rows.

Row 21, seat A (Premium Economy): front row of Premium Economy with Extra leg room.

Row 7, seat A (Business Class): next to a lavatory, with queues, noise and flushing

317 seats: 18 good, 13 mixed, 13 to avoid

Rows 2, 4 and 6, seat A (Business): solo seat on the window side of its pod, with the side table between you and the aisle: the most private kind of Business seat on this map.
Rows 3, 5 and 7, seat K (Business): solo seat set in the middle of its pod, with a side table on each side and no neighbour: one of the most private Business seats on this map.
Rows 8 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 9, seat D (Economy): no seat in front: Aer Lingus's map has no seat 8D, so there is more room for your legs.

Row 7, seats D and G (Business): next to what is likely a galley: Aer Lingus draws an unlabelled box here
Row 26, seats A and C (Economy): backs onto the lavatories or galley Aer Lingus draws behind this row: recline is likely limited, and the queue forms beside you.
Rows 42–46, 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 45, seats A, C, H and K (Economy): backs onto the lavatories or galley Aer Lingus draws behind this row: recline is likely limited, and the queue forms beside you.
