Vietnam Airlines A321 Seat Selection Guide (2026)

The most crowded A321 Vietnam Airlines flies has the best economy seats in the fleet

Fifty-one A321s, four cabins, three seat counts. Faced with that, the obvious move is to hope for the emptiest aircraft — 179 seats rather than 203, sixteen business seats rather than eight. On this fleet the obvious move is wrong.

The 203-seat cabin — four A321ceos and four A321neos, drawn identically — has two rows that the other versions do not have at all. Rows 17 and 31 contain only four seats each: B, C, D and E. There is no A and no G. Every one of those eight seats has direct aisle access with nobody to climb over, and 17B, 17E, 31B and 31E have no seat beside them whatsoever — open space where the window seat would be, and the underseat storage next to you is yours.

One caveat, and it is small: 31E is flagged as slightly narrower than the standard seat. It still has the open space beside it. If you have a choice between 17E and 31E, take 17E.

Before anything else: there is no seat F

Economy on every Vietnam Airlines A321 is lettered A B C | D E G. The window seat on the right-hand side is G, not F. This is not a mistake on the seat map, and it is not a blocked seat — the letter F simply is not used. If you are looking for 22F, you want 22G.

Three cabins, and what the same seat number means on each

How to tell which version you're on

Step 1 — count the business rows

Two rows of business, ending at row 2? You are on a 203-seat aircraft, and rows 17 and 31 are available to you. Four rows, ending at row 4? You are on one of the 16-seat business cabins — 185 or 179 seats.

Step 2 — if business has four rows, look at the exits

On the 185-seat cabin the two short rows are 15 and 28, each missing its D seat. On the 179-seat cabin they are 14 and 27, each missing its E seat. If you would rather look at the back, the 185-seat cabin runs to row 39 and the 179-seat one stops at 38.

The one thing you cannot tell from a map

The 203-seat A321ceo and the A321neo are the same cabin, seat for seat. If your booking says A321neo, everything in this guide's 203-seat section applies unchanged — you get a quieter aircraft and an identical seat plan.

Business Class — the same seat on every version

A 2-2 recliner with a published 45 inches of pitch and 21 inches of width, an adjustable legrest and a four-way headrest. On the 185-seat and 179-seat cabins there are 16 of them across four rows; on the 203-seat cabins there are eight across two.

Row 1 leads the cabin on every version and gets extra room ahead at the bulkhead. As usual the right-hand side pays for it: 1D faces a galley on all four cabins, and on the 203-seat jets so does 1G beside it. 1C has a bulkhead that is 90% solid, so the gap on its right is real but not worth choosing for.

1A is the pick on every version — bulkhead legroom, a properly aligned window, no galley in front of it. If you would rather not be in the front row, the alternative depends on the cabin: on the 185-seat jets it is 3A or 3F, which carry the best windows in that business cabin, and on the 203-seat jets it is 2A or 2G. On the 179-seat cabin there is no standout — rows 2, 3 and 4 all rate alike, so take whichever aisle or window you prefer.

Economy — the 203-seat cabin (rows 10 to 44)

This is the cabin worth understanding properly, because it has the best seats and the strangest rules.

Rows 17 and 31 are the prize, for the reasons above. Take 17B or 17E first, then 31B, then the aisle seats 17C, 17D, 31C and 31D, then 31E last of the eight because it is slightly narrower.

Rows 18 and 32 are the extra-legroom rows — five seats each, A, B, C, E and G, with no D. All of them have open floor ahead and no seatback in front, which means no underseat storage and a tray table that folds out of the armrest. 18E and 32E have no seat beside them, which makes 18E the best of the extra-legroom seats. Note that 32A and 32G pay for their legroom with a window set behind the seat.

19D and 33D are worth knowing about: there is no seat directly in front of either, because the row ahead is a short one. Extra legroom on an aisle seat, without paying for an exit row. No underseat storage.

Row 10 is the first economy row, at the bulkhead behind business. All six seats get extra legroom and all six lose underseat storage. It is a fair trade if you have nothing to keep at your feet.

Elsewhere: the best windows are at rows 12, 15, 20, 33 and 36. Windows sit behind the seat — lean back to see out — at 11A/G, 22A/G, 23A/G, 24A/G, 27A/G and 35A/G. At the back, 41A, 41B and 41C have the lavatory queue behind them, and rows 42, 43 and 44 are all directly against the lavatories. Row 44 is three seats — D, E and G — and 44D adds the galley.

Economy — the 185-seat cabin (rows 10 to 39)

This is the one you are most likely to be on: 39 of the 51 aircraft.

The exit rows are 15 and 28, and both are five seats — A, B, C, E and G, with no D. All five carry extra legroom, no underseat storage and a tray in the armrest. 15E and 28E have no seat beside them, which makes them the two best economy seats on this version.

16D and 29D are the quiet pick: no seat directly in front of either, so genuine extra legroom on an aisle without buying an exit row. Both lose their underseat storage.

Row 10 is the bulkhead row behind business, and it is not uniform. 10A and 10D keep their underseat storage and get extra legroom; 10B, 10C, 10E and 10G get the legroom but lose the storage. If you are choosing within row 10, take A or D.

14A and 14G are the seats to avoid — no window at all, wall only, and they sit immediately in front of the exit row. There is nothing to recommend them.

The best windows are at rows 26, 33 and 35. Windows set behind the seat at 12A/G, 19A/G, 20A/G, 21A/G, 30A/G and 32A/G. At the back, 36A, 36B and 36C have lavatory traffic, and rows 37, 38 and 39 are hard against the lavatories. Row 39 is three seats: D, E and G.

Economy — the 179-seat cabin (rows 10 to 38)

Four aircraft, and the only Vietnam Airlines A321 sub-fleet with seatback entertainment screens rather than streaming alone. Four out of 51 is thin odds, so load your own device whatever your booking says and treat a screen as a bonus.

The exit rows are 14 and 27, both five seats — A, B, C, D and G, with no E this time. 14D and 27D have no seat beside them, so they are the best two economy seats on this version: an aisle seat, extra legroom, and open space on the inboard side.

15D and 28D are the equivalent of the 185-seat cabin's 16D and 29D — no seat in front, extra legroom, no underseat storage.

Row 10 is the bulkhead row and here all six seats lose underseat storage in exchange for the legroom.

12A and 12G are the seats to avoid — no window at all. Note that this is a different row number from the windowless pair on the 185-seat cabin, which is at 14. Best windows at rows 25, 32 and 34; windows set behind the seat at 18A/G, 19A/G, 20A/G, 29A/G and 31A/G. At the back, 35A, 35B and 35C have lavatory traffic and rows 36, 37 and 38 are against the lavatories. 38G is also slightly narrower than standard.

Cabin features

The 203-seat cabin does not get its extra seats by squeezing economy. All three cabins are drawn at the same economy row spacing; the dense version finds its room by deleting two rows of business class and tightening the gaps at the exits and galleys. That is unusual, and it is the reason the crowded jet is not the uncomfortable one.

About the wifi

There is a wireless network on board and there is no internet on board. Those are both true. Vietnam Airlines' onboard system lets you connect a phone or laptop to a portal carrying films, television, music and audiobooks — the same library the widebody seatback screens run — but it does not reach the outside world. You cannot check email, and you cannot stream from your own subscriptions. Download before you fly, and bring a way to prop your phone up, because none of these cabins has a device holder in economy. In-seat power is not documented on any of the four, so arrive with a charged battery.

Quick-pick summary

Frequently asked questions

Why is there no seat F on Vietnam Airlines' A321?

Economy is lettered A B C | D E G on every version. The letter F is simply not used, so the right-hand window seat is G. It is not a blocked seat and it is not an error on the map — if you are looking for 22F, the seat you want is 22G.

Which is the best economy seat on a Vietnam Airlines A321?

17B or 17E, but only on the 203-seat aircraft. Rows 17 and 31 on those jets have four seats instead of six — B, C, D and E, with no window seats at all — and every seat in them has direct aisle access with nobody to climb over. 17B, 17E, 31B and 31E additionally have no seat beside them. On the 185-seat cabin the equivalent picks are 15E and 28E; on the 179-seat cabin they are 14D and 27D.

How many different A321 cabins does Vietnam Airlines fly?

Four page layouts covering three distinct cabins: 185 seats on 39 aircraft, 179 seats on four, and 203 seats on eight — four A321ceos and four A321neos, which are laid out identically. The quickest way to tell which one you are on is to count the business rows: two means 203 seats, four means 185 or 179.

Do Vietnam Airlines A321s have seatback screens?

Mostly no. Three of the four cabins have no screens at all and stream to your own device instead. The 179-seat cabin is the exception, and it is only four aircraft out of 51. Plan for streaming on any Vietnam Airlines A321 and treat a screen as a bonus.

Is there wifi on Vietnam Airlines' A321?

There is an onboard wireless network, but it does not connect to the internet. It carries an entertainment portal — films, television, music, audiobooks — that you reach from your own phone or laptop. You cannot browse, check email or use your own streaming subscriptions. Download what you want before you board.

Which seats have no window?

14A and 14G on the 185-seat cabin, and 12A and 12G on the 179-seat cabin — wall only, no window at all. The 203-seat cabin has no fully windowless seats, though several window seats across all three versions have the window set behind the seat, so you have to lean back to see out.
