Vietnam Airlines Airbus A321neo Seat Selection Guide (2026)
✈️ Quick Verdict
Aircraft: Airbus A321neo — 203 seats, 8 Business + 195 Economy
Layout: Business 2-2, A C | D G, rows 1–2 · Economy 3-3, A B C | D E G, rows 10–44 (no row 13)
Version lottery: No within the neo — but Vietnam Airlines flies four A321 cabins in total, and this 203-seat layout is shared with some A321ceos
Best seats — Business: 1A — bulkhead legroom without 1D and 1G’s galley noise
Best seats — economy: 17B, 17E, 31B and 31E — no seat beside you at all · 18A and 18G for extra legroom with the best window rating
Also excellent: 17C, 17D, 31C and 31D — four-seat rows, direct aisle access, nobody to climb over
Seats to avoid: rows 16 and 30 — restricted recline · rows 42, 43 and 44 — lavatories · 32A and 32G — extra legroom with a restricted window
IFE: streamed to your own device — no seatback screens · Wi-Fi: none
The eight seats worth knowing about
The A321neo’s fuselage narrows at the rear exits, and Vietnam Airlines’ layout does something with that space most airlines do not: rows 17 and 31 have four seats instead of six. They are lettered B, C, D and E — no A, no G — and they sit in the middle of the cabin with an aisle on each side.
The consequence is that all eight of those seats have direct aisle access with nobody to climb over. On a narrowbody where 195 people are in a 3-3, that is close to unheard of.
Four of the eight go further still. 17B, 17E, 31B and 31E have no seat beside them at all. You get the extra side space and the underseat storage next to you is yours. These are the four best economy seats on the aircraft and they carry no surcharge and no special marking.
One caveat worth knowing: 31E is flagged as slightly narrower than standard for the aircraft. It still has the empty space beside it; the seat itself is a little tighter. 17B, 17E and 31B have no such note.
The bulkheads behind them: rows 18 and 32
Immediately behind each four-seat row is a bulkhead row lettered A, B, C, E and G — no D. Both carry extra legroom, with the usual trade-offs: no underseat storage and the tray table in the armrest.
| Row | What you get | Verdict |
|---|---|---|
| 18 | Extra legroom. 18A and 18G carry the best window rating on the aircraft. 18E has no seat beside it | Best extra-legroom row |
| 32 | Same extra legroom, but 32A and 32G have a window set behind the seat. 32E has no seat beside it | Take 32B, 32C or 32E |
If you want legroom and a window, 18A or 18G. If you want legroom and would rather not sit beside anyone, 18E or 32E. Avoid 32A and 32G specifically: they sell the extra legroom against a restricted view.
The trap: rows 16 and 30
Rows 16 and 30 sit immediately in front of the two exit rows. On both, 16B, 16C, 16D, 16E and 30B, 30C, 30D, 30E cannot fully recline because the exit row behind needs a clear path — and neither row carries any extra legroom in exchange.
This is the standard narrowbody trap and it appears twice on this aircraft because the A321 has two exit pairs. Nothing on a booking map distinguishes row 16 from row 15.
Business Class: eight seats, rows 1 and 2
A 2-2 recliner lettered A C | D G across two rows — eight seats, four of them on the aisle. There are no solo seats and no direct-aisle pods; this is a short-haul regional Business cabin.
Row 1 leads the cabin with extra room ahead at the bulkhead. 1D and 1G sit beside the forward galley and take noise and bright light during meal preparation; 1C faces a mostly-full bulkhead covering about 90% of the frontage, so its practical legroom gain is small. 1A is the cleanest seat in the cabin. Row 2 is the same seat without the bulkhead space.
Economy: the rest of the cabin
Economy runs rows 10 to 44 in a 3-3, lettered A B C | D E G. There is no F seat and no row 13.
Row 10 is the front economy bulkhead: extra legroom, no underseat storage, tray in the armrest.
Six pairs of window seats have a window set behind them rather than aligned: 11A, 11G, 22A, 22G, 23A, 23G, 24A, 24G, 27A, 27G, 35A and 35G. The view is restricted rather than absent.
The back of the cabin
Row 41 picks up lavatory traffic at A, B and C. Row 42 puts 42A, 42B and 42C against a lavatory door and 42D, 42E and 42G in the queue. Row 43 is against the lavatory doors across the whole row, and 43A has no window at all while 43G has one set behind the seat. Row 44 is the last row — D, E and G only — all against the lavatories, with 44D also beside the galley.
Rows 19 to 29 and 33 to 40 are the clean stretches.

Entertainment and Wi-Fi
There are no seatback screens on this aircraft. Audio and video content is streamed to your own device, so bring a phone or tablet and something to prop it on. There is no Wi-Fi, so the streaming is from an onboard server rather than the internet.
How this fits Vietnam Airlines’ A321 fleet
Vietnam Airlines flies A321s in four different cabins, from 179 seats to 203, and the 203-seat layout covered here is used by both A321neos and some A321ceos — laid out identically, so the seat advice holds either way. The instinct to hope for the emptiest aircraft is wrong on this fleet: the 203-seat jets are the densest and they are the only ones with rows 17 and 31.
For the full picture across all four cabins, see the Vietnam Airlines A321 fleet guide. For the single A320neo, see the A320neo guide.
Frequently asked questions
What is the best seat on Vietnam Airlines’ A321neo?
17B, 17E or 31B. Rows 17 and 31 have only four seats, and these have no seat beside them at all — extra side space, your own aisle, and the underseat storage next to you. No surcharge.
Why do rows 17 and 31 have only four seats?
The fuselage narrows at the rear exit doors, and the layout uses that space for a four-abreast row rather than squeezing in six. It is why every seat in both rows has direct aisle access.
Which row has the most legroom?
Rows 18 and 32, the bulkheads behind the four-seat rows. Row 18 is the better of the two — 18A and 18G have the best window rating on the aircraft, while 32A and 32G have a window set behind the seat.
Which rows should I avoid?
Rows 16 and 30, where the centre four seats cannot fully recline and get no extra legroom for it, and rows 42 to 44 at the back, which sit against the lavatories.
Are there seatback screens or Wi-Fi?
Neither. Entertainment is streamed to your own device from an onboard server, and there is no in-flight Wi-Fi.
Is the A321neo different from Vietnam Airlines’ other A321s?
The 203-seat layout described here is shared between A321neos and some A321ceos, so it is identical either way. Vietnam Airlines also flies 179-seat and 185-seat A321 cabins, which have different row numbers and different problem seats.
