Aer Lingus Airbus A321LR seat map

Aer Lingus's own seat map for this A321LR shows 184 seats: 16 Business and 168 Economy. Business runs from row 2 to 6 in staggered pods: rows alternate between solo seats and pairs, so some seats sit alone by the window and others share a pod with a neighbour. Economy runs from row 7 to 34 in a 3-3 layout. Aer Lingus colours its Economy seats by what they cost to choose: Extra Legroom in rows 7 and 14 to 15, Preferred in rows 8 to 10, Front in rows 11 to 13, and Standard behind. Rows 14 and 15 are exit rows. On short-haul flights Aer Lingus sells this Business cabin as AerSpace, with a fully lie-flat seat. Aer Lingus publishes one map, titled A321-NEO/XLR, for its A321neo family.

Best and worst seats

Best seats

  • Rows 3 and 5, seats A and 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.

  • Row 7, seats A, B, C, D, E and F · Economy

    Bulkhead row sold as an Extra Legroom seat: nobody in front of you, right behind the Business cabin.

  • Rows 14–15, seats A, B, C, D, E and F · Economy

    Overwing exit row, sold as an Extra Legroom seat: more room for your legs. Aer Lingus doesn't seat children under 14 or people with reduced mobility in exit rows.

Trade-offs

  • Row 2, seats A and K · Business

    Bulkhead row, so nobody reclines into you

  • Row 4, seat A · Business

    Window seat paired with 4C in one pod. Aer Lingus's map shows no aisle beside it, so you likely step past your neighbour to get out.

  • Row 4, seat K · Business

    Window seat paired with 4H in one pod. Aer Lingus's map shows no aisle beside it, so you likely step past your neighbour to get out.

  • Row 6, seat A · Business

    Window seat paired with 6C in one pod. Aer Lingus's map shows no aisle beside it, so you likely step past your neighbour to get out.

  • Row 6, seat K · Business

    Window seat paired with 6H in one pod. Aer Lingus's map shows no aisle beside it, so you likely step past your neighbour to get out.

Seats to avoid

  • Row 13, seats A, B, C, D, E and F · Economy

    In front of an overwing exit row, so recline is likely limited

  • Row 34, seats A, B, C, D, E and F · 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.
