Try Cabin
The Aer Lingus A321LR offers a mixed cabin experience with lie-flat business seats and spacious economy configurations. This guide reveals the best seats to book and which ones to avoid on this long-range aircraft.
Business Class
Aer Lingus equips the A321LR with 16 business class seats arranged in an alternating 2-2 and 1-1 configuration. Each seat converts into a fully flat bed measuring 77 inches in length with 22-inch width, providing excellent comfort for long-haul transatlantic flights. The alternating layout creates both paired seating and single 'throne' seats for solo travelers seeking maximum privacy. However, no privacy doors are installed between seats.
Economy Class
Economy features the standard 3-3 seating layout with pitch varying between 30.5 and 35 inches depending on row location. The wider spacing in select rows offers noticeably improved legroom for standard passengers. No premium economy cabin is available on this aircraft configuration.
Best seats
Seat | Cabin | Why |
|---|---|---|
5A | Business | Throne seat with single occupancy, direct aisle access, and full-flat bed comfort without neighbor disruptions |
5K | Business | Throne seat on opposite side offering identical privacy and ergonomic benefits as 5A |
14A-14F | Economy | Rows 14-15 feature 35-inch pitch, the maximum legroom available in economy cabin |
15A-15F | Economy | Premium economy-equivalent spacing with 35-inch pitch for enhanced comfort on long flights |
Seats to avoid
Seat | Cabin | Why |
|---|---|---|
Row 6 | Business | Proximity to galley and lavatory creates noise and traffic disruptions affecting sleep quality |
Rows 33-34 | Economy | Reduced 30.5-inch pitch results in cramped legroom; likely near rear lavatories and galleys |
