Air Transat A321LR Seat Selection Guide (2026)

The trap: an exit row with no window seats

Row 26 sits at the A321LR's mid-cabin door and shows up on a booking map as an exit row with all the legroom that implies. What the map does not make obvious is that the row consists of four seats: 26B, 26C, 26H and 26J. There is no 26A and no 26K — the door itself occupies both window positions.

So the only exit row in the rear half of the aircraft offers you a choice between two middle seats and two aisle seats. If you specifically want legroom and a window on this aircraft, row 26 cannot give it to you at any price.

The seat letters skip D, E and F

Air Transat letters its Economy cabin A, B, C on the left and H, J, K on the right. There is no D, E or F anywhere on the aircraft, and no I. This is not a mistake on your boarding pass.

Practically, it means the two seats you want on the right-hand side are K (window) and H (aisle), with J as the middle. On the left it is the conventional A window and C aisle, with B in the middle. Couples booking together should take A and C, or H and K, and leave the middle for the algorithm to fill last.

Club Class: three rows, and one of them is best

Club is a 12-seat cabin in rows 1 to 3, laid out 2-2 with the letters A and B on the left, H and K on the right. These are wide domestic-first-style recliners at around 38 inches of pitch, with footrests, six-way headrests and a seatback screen. Nobody lies flat on this aircraft — judged as a premium recliner rather than a business-class bed, it is a comfortable way to cross.

• Row 2 — the pick of the cabin. It has a seat in front of it to recline into, no bulkhead at your feet, and it is away from the galley traffic at the very front.
• Row 1 — bulkhead legroom, but bulkhead compromises too: no under-seat storage for take-off and landing, and the forward galley and lavatory right there.
• Row 3 — the last Club row. Fine, but it sits directly against the Economy divider, so you get the queue for the forward lavatory beside you.

The mid-cabin lavatories stand where row 25 should be

Between rows 24 and 26 the A321LR carries a lavatory on each side of the aisle. They occupy a full row's worth of cabin, which is why the numbering skips straight from 24 to 26. That single fact accounts for most of what is wrong with the middle of this cabin:

• There is no row 25. The numbering runs 23, 24, then straight to 26 — the lavatories stand exactly where row 25 would be. If you are counting rows back from the exit, count carefully.
• Row 24 backs directly onto the lavatory wall. Restricted recline, a door opening and closing behind your head for seven hours, and the queue standing over you for a crossing on which the lavatories are in near-continuous use.

On a two-hour hop this would barely register. On an overnight Atlantic crossing it is the difference between sleeping and not, and it is the single most common seat-selection mistake made on this aircraft.

Economy: best seats

• 16A / 16K — the overwing exit row, in a full six-seat row. Extra legroom, a window, and a normal recline. The best seats in Economy.
• 26C / 26H — the mid-cabin exit. The most floor space on the aircraft, on the aisle, with an empty window position beside you rather than a stranger.
• Row 4 — the first Economy row, directly behind Club. Bulkhead legroom and served first.
• Rows 5 to 12 — forward of the wing and well clear of both the mid-cabin and rear lavatories. The quietest ordinary seats on the aircraft.
• Row 27 — directly behind the mid-cabin exit, so it has the door space in front of it rather than a reclining seat back.

Economy: seats to avoid

• Row 15 — sits immediately in front of the overwing exit at row 16, so it is fixed upright with no extra legroom in exchange.
• Row 24 — against the mid-cabin lavatory wall, with restricted recline and the queue standing over you for the whole crossing. Row 25 does not exist, so row 24 is the row that takes the hit.
• Row 36 — the last row, and it exists only on the left-hand side. There is no 36H, 36J or 36K; the rear galley and lavatory occupy that half of the cabin. 36A, 36B and 36C sit against the rear wall with reduced recline and the lavatory door directly across the aisle.
• Row 35 — one better, but still in the rear service area.
• 26B / 26J — exit-row legroom, but they are middle seats with no window on either side of them. Only worth it if legroom is the only thing you care about.

Cabin features

Exits and lavatories: one lavatory at the front beside Club, two mid-cabin between rows 24 and 26, and one at the rear behind row 36 alongside the aft galley. The overwing exit is at row 16 and the mid-cabin door at row 26. Row 13 is present on this aircraft — Transat does not skip it — but row 25 is not.

Frequently asked questions

Why is there no 26A or 26K?

Row 26 sits at the mid-cabin door, and the door occupies both window positions. The row exists as 26B, 26C, 26H and 26J only.

Why are the seats lettered A B C and H J K?

It is Air Transat's convention across the fleet. There is no D, E or F on the aircraft, and I is skipped as usual to avoid confusion with the numeral 1.

Is Club Class lie-flat?

No. Club is a wide recliner at around 38 inches of pitch with a footrest — comparable to a domestic first-class seat rather than a transatlantic business bed.

Which is the best exit row?

It depends what you want. Row 16 over the wing is a full row, so it is the only one where you can have legroom and a window. Row 26 at the mid-cabin door has more floor space but no window seats at all.

Where are the lavatories?

Four: one at the front by Club, two mid-cabin between rows 24 and 26, and one at the rear behind row 36. The mid-cabin pair stands where row 25 would otherwise be, and is what makes row 24 worth avoiding on an overnight flight.

Does the A321LR have seatback screens?

Yes, 10.1-inch seatback screens throughout, with USB-A and 110V power. This is a genuine long-haul fit-out rather than a short-haul narrowbody cabin.
