Aer Lingus A321neo LR & A321XLR Seat Selection Guide (2026)

Aer Lingus flies its transatlantic narrowbody in two guises. The A321neo LR opened Dublin to Hartford, Philadelphia, Cleveland and a string of other US East Coast and Midwest cities; the newer A321XLR extends the same idea further. Twelve aircraft fly the LR configuration; no count is published for the XLR.

If you are trying to work out which one you have booked so you can pick a different seat: you do not need to. The two cabins are identical seat for seat. Same 16 Business seats over rows 2 to 6, same 168 Economy seats over rows 7 to 34, same overwing exits at rows 14 and 15, same four throne seats, same two windowless seats at 25A and 25F. A seat chosen on one applies exactly to the other.

What does change is the shell around it. The XLR carries Airbus's Airspace cabin — wider interior trim and noticeably larger overhead lockers — along with the Panasonic Next entertainment system, which serves content on demand rather than the LR's gate-to-gate stream. Both aircraft have Panasonic satellite Wi-Fi in the 10–40 Mbps range.

Business Class: sixteen seats, four of them thrones

Business is a staggered 2-2 lie-flat cabin over rows 2 to 6, lettered A and C on the left, H and K on the right. There is no B, D, E, F, G or J seat anywhere in it, and there is no row 1. The rows alternate:

• Rows 2, 4 and 6 carry four seats — a window seat and an aisle seat on each side, with a console between them.
• Rows 3 and 5 carry two seats — 3A and 3K, 5A and 5K — each a single seat centred between two consoles. These are the thrones.

That layout has a consequence worth knowing before you pay. only ten of the sixteen seats have direct aisle access: the four thrones, plus the six aisle seats 2C, 2H, 4C, 4H, 6C and 6H. The even-row window seats — 2A, 2K, 4A, 4K, 6A and 6K — sit behind a console and a neighbour. On a Dublin–Chicago overnight where your neighbour is asleep and flat, that matters.

Best in Business: 5A and 5K

Both are thrones, and both have two windows rather than one — the only seats in the cabin with that combination. Nobody beside you, nobody to climb over, console space on both sides, and the most glass. Row 5 also sits further from the forward galley and lavatory than row 3 does.

3A and 3K are the same seat with one window each and a little more forward-galley traffic. They are the second pick and there is not much in it.

The rest of the cabin

If the thrones are gone, take an aisle seat: 2C, 2H, 4C, 4H, 6C or 6H. You give up the window but keep the direct path to the aisle, which is the thing the even-row window seats do not have.

Among the window seats, 2A and 2K have two windows each on the LR, and 6K also has two. Row 6 is the last Business row, and contrary to what is often assumed there is no galley or lavatory behind it — only a curtain and then the Economy bulkhead at row 7. There is no penalty at any row 6 seat. What you get instead is the boarding stream walking past you to reach Economy.

The seats themselves are Thompson Aero Vantage: fully flat beds of about 77 inches, roughly 22 inches wide, with a seatback screen at every seat.

Economy: rows 7 to 34

The pitch, honestly

Rows	Pitch	Notes
7	Bulkhead	Extra legroom, but no under-seat storage and the tray and screen stow in the armrest
8–13	About 31in	Standard front Economy
14–15	About 33in	The overwing exit rows — 84–85cm, about 6–7cm more than the cabin norm
16–34	About 31in	Standard rear Economy

Rows 14 and 15 are the best Economy seats on the aircraft and the extra pitch is real — but it is about two inches, not five. On a six or seven-hour crossing two inches is still worth having, and all twelve seats keep their recline, and row 13 keeps its recline too.

25A and 25F: no window at all

This is the one thing on the aircraft that costs you if you do not know it. 25A and 25F have no window. Both are wall-only positions — not a misaligned window you can lean back and look through, but nothing at all. Everything else about row 25 is unremarkable: standard pitch, standard recline, the four inner seats are perfectly ordinary.

If you want a window in that stretch of the cabin, 21A and 21F are four rows ahead of it with perfect alignment, and 23A and 23F work too.

The best and worst windows

Perfectly aligned pairs: 19A/19F and 21A/21F, plus 23F, 30A and 32A on their own. Those are the seats to pick if a clear view is the point.

Windows set behind the seat — you lean back to see out: 12A/12F, 16A/16F, 18A/18F, 24A/24F, and 27A and 29A on the left side only.

The back of the cabin, and which half of it to sit in

The rear lavatory on this aircraft sits on the left-hand side behind row 34, with a galley on the right. That asymmetry decides the last two rows:

• Avoid 33A, 33B, 33C and 34A, 34B, 34C, 34D — all directly against the lavatory door, with 34C and 34D catching the galley as well.
• 33E, 33F, 34E and 34F are fine. There is nothing against them. 34F even has a window. If the back of the aircraft is all that is left, take the right-hand side.
• 33D catches some lavatory traffic but is not against the door.

This is a genuinely useful piece of asymmetry: on most narrowbodies the last two rows are uniformly bad, and here half of them are not.

A321neo LR vs A321XLR: what actually differs

	A321neo LR	A321XLR
Fleet count	12 aircraft	Not published
Configuration	16J / 168Y	16J / 168Y — identical
Row and seat numbering	Business 2–6, Economy 7–34	Identical
Exit rows	14 and 15	14 and 15
Windowless seats	25A, 25F	25A, 25F
Cabin interior	Standard A321neo cabin	Airbus Airspace — wider trim, larger overhead lockers
Entertainment	Panasonic, gate to gate	Panasonic Next, on demand
Wi-Fi	Panasonic eXConnect, 10–40 Mbps	Panasonic eXConnect Ku-band, 10–40 Mbps

The practical upshot: if you have a choice of flights and the aircraft type is shown, the XLR gives you a roomier-feeling cabin and better overhead bin space for the same seat. If you do not have a choice, nothing about your seat selection changes.

A321 or A330? Which Aer Lingus transatlantic aircraft to pick

Aircraft	Why you might prefer it
A321neo LR / XLR	A 16-seat Business cabin with four true thrones, faster boarding and disembarking, and the same lie-flat bed as the widebody
A330-300	A 2-4-2 Economy cabin that suits couples and families far better than 3-3, and more lavatories per passenger

Quick picks by traveller

If you are	Pick	Why
Solo in Business	5A or 5K, then 3A or 3K	Throne seats; row 5 has two windows each
A couple in Business	2A + 2C, 4A + 4C or the H/K equivalents	The paired rows put you side by side with a console between
Tall in Economy	Rows 14 or 15	About 33in with full recline
After a view	19A/19F or 21A/21F	Perfect window alignment; never 25A or 25F
Stuck at the back	34E or 34F, not 34A to 34D	The rear lavatory is on the left-hand side only
First off the aircraft	Row 7, accepting the trade-offs	Economy bulkhead: extra legroom, no under-seat bag, tray in the armrest

Frequently asked questions

Is the Aer Lingus A321XLR cabin different from the A321neo LR?

Not in any way that changes your seat choice. Both are 16 Business and 168 Economy, Business over rows 2 to 6 and Economy over rows 7 to 34, with the exits at rows 14 and 15 and no window at 25A or 25F on either. The XLR adds Airbus Airspace interior trim with larger overhead lockers, and swaps the LR's gate-to-gate entertainment for Panasonic Next on demand.

Which Aer Lingus A321 Business seats are best for solo travellers?

5A and 5K. They are throne seats — a single seat with a console on either side, nobody beside you and nobody to climb over — and they are the only seats in the cabin with two windows each. 3A and 3K are the same seat with one window and a little more forward-galley traffic.

Do all Aer Lingus A321 Business seats have direct aisle access?

No — ten of the sixteen: the four thrones at 3A, 3K, 5A and 5K, plus the aisle seats 2C, 2H, 4C, 4H, 6C and 6H. The six even-row window seats — 2A, 2K, 4A, 4K, 6A and 6K — sit behind a console and a neighbour.

Are there Aer Lingus A321 seats with no window?

Yes: 25A and 25F, on both the LR and the XLR. Both are wall-only positions. Several other seats have a window set behind them — 12A/12F, 16A/16F, 18A/18F, 24A/24F, 27A and 29A — but those at least have glass to lean back to.

Is it worth paying for rows 14 and 15 in Economy?

On a transatlantic sector, yes, with the caveat that the gain is about two inches rather than the five it is sometimes quoted at. Rows 14 and 15 measure 84–85cm against a cabin norm of about 78cm, and all twelve seats keep their recline.

Which Aer Lingus A321 seats should I avoid?

25A and 25F for the missing window. Then 33A to 33C and 34A to 34D, which sit against the rear lavatory on the left-hand side, with 34C and 34D also next to the galley. 34E and 34F are genuinely fine — the asymmetry at the back of this cabin is real.

Are the Business seats fully flat?

Yes. All sixteen are Thompson Aero Vantage seats that convert to fully flat beds of about 77 inches, with a seatback screen at every seat.
