China Eastern A330-300 Seat Selection Guide (2026)

The trap: the same business fare buys two different aircraft

Book China Eastern business class on an A330-300 and you are entering a genuine coin flip. Seventeen of the 27 aircraft — type 33L — carry Thompson Aero Vantage XL seats in 1-2-1. Thirty-two seats, every single one with direct aisle access, nobody climbing over anybody.

The other ten — type 333 — carry a 2-2-2 cabin. Thirty-six seats, six across, and only the two centre seats in each row, D and H, have an aisle to themselves. Twelve of the 36 seats. If you end up at 07A or 09L you are stepping over a stranger every time you want to stretch.

And it goes further. The 33L has a 32-seat premium economy cabin at rows 25 to 28. The 333 has no premium economy at all — where that cabin would be, there is more economy. Two aircraft, same type code on the ticket, one with three cabins and one with two.

That last one is worth reading twice. If you copy a seat number from a review of the wrong aircraft, "35F" is an inboard centre seat on one jet and a trapped middle seat on the other.

Business class on the 33L (rows 6–12 and 15)

This is the good one. Thompson Vantage XL in 1-2-1, thirty-two fully flat seats, every one of them with unobstructed access to an aisle. There is no bad seat in this cabin, only better ones.

The layout is staggered, which means the window pods alternate position row by row. In the odd rows — 7, 9, 11 and 15 — the bed sits hard against the fuselage with the side console between you and the aisle. That is the private half of the cabin. In the even rows — 6, 8, 10 and 12 — the seat is set about fourteen inches inboard with the console against the wall, so you are closer to passing traffic.

• Best in the cabin — 11A and 11L. An odd row, so you get the fuselage-side stagger, and the window here lines up squarely with the seat rather than sitting behind your shoulder.
• Equally good — 15A and 15L. Same aligned window, same private stagger. Row 15 has a galley behind it, but that noise falls on 15D and 15H, not on the window pods.
• Solid — 7A, 7L, 9A, 9L. Private stagger, one or two windows, nothing against them.
• Fine but less enclosed — any of the even rows. 6, 8, 10 and 12 put you nearer the aisle. Still flat, still direct access.
• The only real caveat — 15D and 15H. Centre seats in the last row, with the galley immediately behind. Expect noise and light through meal service.

A word on the centre seats if you are travelling as a pair: D and H sit side by side in every row, but a full console separates them — roughly twenty inches of furniture. This is not a honeymoon suite. They are simply the two closest seats in the cabin, and each still has its own aisle.

Business class on the 333 (rows 6–11)

Six rows of six, 2-2-2. The centre pair D and H are the seats to hold out for: they sit apart from each other, each against an aisle, and nobody has to climb over them. The window seats A and L are trapped behind C and J respectively.

• Best overall — 06D and 06H. Row 6 leads the cabin at the bulkhead, so there is extra room ahead, and these two carry the private aisle as well.
• Best window — 08A and 08L. The only business row on this variant with a properly aligned window.
• Reliable — 07D, 07H, 09D, 09H, 10D, 10H, 11D, 11H. All the centre seats work. Pick on position, not access.
• Only if you must — any A or L. The window is nice; the exit is not.

One note on the numbers: some listings still describe this jet as 36 business and 262 economy, or 38 and 262. The current seat map plots 36 business seats and 264 economy, which is what this guide uses.

Premium economy — 33L only, rows 25–28

Thirty-two seats in 2-4-2 over four rows, and the cabin is well positioned: rows 26, 27 and 28 have nothing flagged against them at all, which is rare. The problem is confined to the front row.

Row 25 is the bulkhead. There is no underseat storage, the tray and screen are in the armrest so the seat is effectively narrower, and 25A and 25C sit immediately beside a lavatory. 25D, 25H, 25J and 25L are close enough to catch the queue.

Book 25E or 25F if you want the bulkhead legroom — they are the only two seats in that row clear of the lavatories. Book row 27 or 28 if you would rather have normal storage and a normal tray; those rows are as clean as premium economy gets on this aircraft.

Economy

Both variants are 2-4-2 at around 32 inches. The two-seat window pairs are the draw: no middle seat, one person between you and the aisle.

The hidden pair: 12D and 12H on the 333

Row 12 on the two-class jet is two seats wide. That is the entire row — D and H, nothing else, tucked in immediately behind business class. Both have extra legroom, both have an aisle to themselves, and both have open floor where a neighbour would normally sit, with that underseat space yours to use.

The costs are real but small: no underseat storage directly in front, and the tray and screen live in the armrest because there is no seatback ahead. On a jet with no premium economy cabin, these two seats are the closest thing to it, sold at an economy fare. They are the first thing to look for when the seat map opens.

Row 34 on the 333: the legroom row

On the 333, economy starts oddly. Rows 31, 32 and 33 are window pairs only — A, C, J and L, with no centre block beside them, because a cabin monument occupies the middle. Then row 34 opens up to the full eight across, and its centre four (34D, 34F, 34G and 34H) face that monument with about 29 inches of clear floor ahead. That is far more legroom than any other economy row on the aircraft.

The trade is the usual bulkhead one: no underseat storage, tray in the armrest. If you value stretching out over convenience, take it. Of the window-pair rows ahead of it, 33A and 33L are the pick — furthest from the galley and the only one of the three with an aligned window.

Windowless window seats

On the 333, 35A and 35L are wall only — sold as window seats, no window. The 33L has no equivalent, which is one point in its favour.

On both variants, 38A/38L and 63A/63L (333) and 67A/67L (33L) have windows set behind the seat, so you lean back to see out rather than looking straight through.

The exit row is the worst row in economy

Row 61 is the over-wing exit row on both variants, and on both it is a trap. 61A and 61L sit against exit doors L3 and R3, which intrude into about half the seat width from roughly eight to ten inches ahead. You are paying for extra legroom and getting a door in your shoulder.

On the 333 it is worse still: the whole of row 61 has a lavatory immediately ahead, and 61A and 61L have a misaligned window on top of the door intrusion. Only 61C and 61J escape the lavatory. On the 33L there is no lavatory hard against the row — just the queue — so 61C and 61J are the reasonable picks there too.

Rows to skip

• 33L: rows 41, 42 and 43 back onto the mid-cabin lavatories. Row 43 is only four seats wide. Note also that rows 44 to 60 do not exist — the numbering jumps.
• 333: rows 47 and 48 back onto the mid-cabin lavatories. Numbering jumps from 48 to 61.
• Both: rows 75 to 78 are the rear lavatory block. Rows 77 and 78 are three seats wide (D, F, H) and 78 has a lavatory immediately in front of it.

The clean stretch

On the 33L, 70A and 70L are the one row in the rear cabin with a perfectly aligned window, and rows 62 through 72 are clean generally. On the 333, 68A/68L and 70A/70L are the aligned-window rows, and 73D and 74D have nobody beside them thanks to the fuselage taper.

FAQ

Does China Eastern's A330-300 have premium economy?

On 17 of the 27 aircraft, yes — a 32-seat cabin at rows 25 to 28. The other 10 have no premium economy cabin at all. If premium economy is why you are booking, confirm the seat map shows a block at rows 25–28 before you pay.

Is China Eastern A330-300 business class fully flat?

On the 33L it is a Thompson Vantage XL in 1-2-1 with all 32 seats reaching an aisle directly. On the 333 it is a 2-2-2 cabin where only the 12 centre seats have their own aisle. Both are long-haul business products; the access difference is what separates them.

Which A330-300 am I more likely to get?

The 33L, at 17 of 27 aircraft. But the split is close enough that it is worth checking rather than assuming. The quickest tell is the number of seats across the front business row: four means 33L, six means 333.

What is the best economy seat on the China Eastern A330-300?

On the 333, 12D or 12H — a two-seat row immediately behind business with extra legroom, direct aisle access and nobody beside you. On the 33L, 70A or 70L for a clean aligned-window pair, or 25E/25F if you can stretch to premium economy.

Should I pay for the exit row?

Not at 61A or 61L. On both variants the exit door intrudes into roughly half the seat width, and on the 333 there is a lavatory immediately ahead of the whole row as well. 61C and 61J are the only exit-row seats worth the money.

Why do the row numbers jump?

Both variants skip a block of numbers where the mid-cabin galley and lavatories sit. The 33L runs economy 31–43 and then 61–78; the 333 runs 31–48 and then 61–78. Business on the 33L also skips 13 and 14. Nothing is missing from the aircraft — the numbering just leaves gaps.
