Asiana A350-900 Seat Map & Best Seats (2026)

Asiana's A350-900 is the most consistent long-haul aircraft the airline flies: fifteen airframes, one configuration, no retrofit splitting the fleet. There is no version lottery to worry about. What there is instead is a Business cabin where two seats with the same letter can be completely different seats depending on the row number — and that is the thing worth getting right.

The trap: in Business, odd and even rows are not the same seat

Business is a staggered 1-2-1 — Stelia Solstys — not a reverse herringbone. In a staggered cabin the seats shift outboard and inboard from row to row, and the letters change with them:

• Even rows — 8, 10 and 12 — use A and J. These sit hard against the fuselage, with the side console between you and the aisle. This is the private seat: the aisle traffic passes on the far side of a solid surface.
• Odd rows — 7, 9, 11 and 14 — use B and H. These sit inboard, next to the aisle, with the console on the window side. Easier to step out of, more exposed.

Every one of the 28 seats has direct aisle access either way — that is not the differentiator. Privacy is. If you want to sleep undisturbed, book an even row.

The centre pairs alternate the same way. E and F, in rows 7, 9, 11 and 14, sit side by side — the pair to book if you are travelling with someone. D and G, in rows 8, 10 and 12, are held apart by consoles, which suits two colleagues better than two people who want to talk.

Two exceptions worth knowing

7B and 7H have the best windows in the cabin. Row 7 is an odd row, so both seats sit inboard by the aisle — and yet their window alignment is the best in Business, where every other window position is merely average. If the view matters more to you than the privacy, row 7 is the counter-intuitive pick; the cost is the forward galley immediately ahead of it.

Row 12 is marked down, and row 14 is why. The bassinets mount at 14B and 14H, which puts potential infant noise directly behind all four seats in row 12. It is the only row in Business rated below the rest. If you are choosing an even row for privacy, take 8 or 10 rather than 12.

The other quirk: the cabin starts at row 7

There is no row 1 through 6 on this aircraft. Business begins at row 7 and runs to row 14, and there is no row 13 either — the sequence is 7, 8, 9, 10, 11, 12, 14. Economy then starts at row 28, a long way further into the numbering than the cabin's physical position suggests.

Economy Smartium — rows 28 to 31

Asiana does not fly a premium economy cabin on the A350. What it sells instead is Economy Smartium: the first four rows of economy, with more legroom but the same seat, the same width and the same 3-3-3 layout. Thirty-six seats.

The gap is real. The Smartium rows measure about 38 inches of pitch, roughly six inches more than the standard economy behind them — so standard economy sits at around 32 inches. That is a bigger step than most airlines' extra-legroom products.

It is rows 28, 29, 30 and 31, and nothing else. Row 32 is where standard economy begins, and the seat colour changes on the map to show it.

Best: row 30. It is the only Smartium row with no complication at all — no bulkhead, no bassinets, and no misaligned windows. 29A, 29J, 31A and 31J all have windows set behind the seat, and row 28 is the bulkhead.

Row 28 is a mixed bag. The legroom is genuinely generous — 75 to 76cm, about 29 to 30 inches, to the wall — but nothing stows under a seat in front, the tray table lives in the armrest so the seat is effectively narrower, and the bassinets mount at 28A, 28D, 28F and 28J. The right-hand end of the row (28G, 28H, 28J) also has a lavatory ahead of it.

Economy — rows 28 to 60

A 3-3-3 cabin lettered A B C | D E F | G H J. Asiana ends at J and does not use a K seat — if you are used to a Boeing 3-3-3 running to K, the right-hand window here is J.

Best in standard economy: 51A and 51J. The best window alignment in the cabin — two of only four economy seats that good — and a long way from either galley. 58A and 58J have the same great windows but the rear lavatories directly behind, so take them only if the view is what you are after.

46B and 46H are the odd ones. Row 46 has no A and no J seat, which means nobody sits beside 46B or 46H: extra legroom, direct aisle access, and the underseat space next to you is your own. The catch is absolute — neither seat has a usable window. If you are booking for space rather than daylight, they are among the roomiest economy seats on the aircraft.

47A and 47J get extra legroom for free, because row 46 has no seat in front of them. The trade-off is no underseat storage and the tray table in the armrest.

Avoid rows 43 and 44 — the mid-cabin lavatories sit behind them and row 44's recline is limited as a result. Row 45 is centre block only (45D, 45E, 45F), at a bulkhead with a lavatory immediately ahead and a bassinet alongside. At the back, avoid row 59, and row 60, which is centre block only and does not recline at all.

Quick-pick summary

FAQ

Does Asiana's A350-900 have premium economy?
No. It has two cabins. Economy Smartium is an extra-legroom band inside economy at rows 28 to 31 — the same seat with about six more inches of pitch, not a separate product.

Which are the best Business seats?
8A, 8J, 10A and 10J. In this staggered cabin the even rows sit against the window; the odd rows sit by the aisle. Row 12 is the even row to skip — it is marked down for infant noise from the bassinets in row 14.

Which Business seats have the best view?
7B and 7H. They sit by the aisle rather than at the wall, and the forward galley is just ahead, but their window alignment is the best in the cabin.

Why does Business start at row 7?
That is how Asiana numbers this aircraft. Rows 1 to 6 do not exist, and neither does row 13 — Business runs 7, 8, 9, 10, 11, 12, 14.

How much more legroom is Economy Smartium?
About 38 inches of pitch against roughly 32 inches in standard economy — six inches, in rows 28 to 31 only.

Is there a K seat in economy?
No. The 3-3-3 is lettered A B C, D E F, G H J. The right-hand window seat is J.

Which economy seats should I avoid?
Rows 43 and 44 (mid-cabin lavatories behind), row 45 (centre block only, lavatory ahead), row 59, and row 60 — the last row, centre block only, which does not recline.
