Hainan Airlines A330-300 Seat Selection Guide (2026)

Hainan Airlines Airbus A330-300 Business Class cabin
Eighteen of Hainan’s A330-300s carry 24 Super Diamond Business seats; three carry 32 Stelia Solstys seats instead

Hainan Airlines flies two Airbus A330-300s, and unusually for a version lottery, neither one is a bad outcome in Business Class. Both are 1-2-1, both give every passenger a direct aisle. The difference is that one has eight more Business seats and the other has nineteen more Economy seats, and they hide two completely different sets of problem rows.

Both aircraft book as an A330-300 and both carry the equipment code 333, so nothing on a booking confirmation separates them. The seat map is the tell, and it is an easy one.

✈️ Quick Verdict

  • Aircraft: Airbus A330-300, two configurations
  • Configurations: 292 seats (32J Solstys + 260Y) · 303 seats (24J Super Diamond + 279Y)
  • Fleet: three aircraft fly the 292-seat layout and eighteen fly the 303-seat layout
  • Version lottery: Yes — but Business is 1-2-1 with full direct aisle access on both
  • Most likely aircraft: the 303-seat Super Diamond jet, by six to one
  • Best Business seats: 18A and 18K on the 303-seat jet; 15C/15H and 17C/17H on the 292-seat jet
  • Business seats to avoid: 20A and 20K on the 292-seat jet (no window at all); 17A and 17K on the 303-seat jet (poor alignment)
  • Best Economy seats: 53A/53K and 55A/55K on either aircraft — two windows each, quiet mid-cabin
  • Economy seats to avoid: rows 46–48 and 63–64 (292-seat); rows 48–50 and 65–67 (303-seat)
  • Wi-Fi: None recorded on either configuration. Thales Avant IFE on both.

The Version Lottery

Both cabins are 1-2-1 flat beds with direct aisle access for every seat, so the choice is not between a good product and a bad one. It is between two different geometries.

⚠️ Do not go looking for a code on your booking

Reference material sometimes files the Super Diamond aircraft under a "338" label. That is a cataloguing convention, not what the aircraft books as: both configurations carry the equipment code 333, and the A330-800 — the real 338 — is a different aircraft that Hainan does not operate. Your booking confirmation will say 333 either way, so count the Business rows instead.

How to Tell Which Version You’re On

Both aircraft skip rows 13 and 14, and both jump straight from the last Business row to row 31 in Economy, so neither gap identifies anything.


Business Class — 303-seat jet (Super Diamond)

Twenty-four Collins Aerospace Super Diamond seats across rows 11, 12, 15, 16, 17 and 18. One seat per side, a pair in the centre, and every A and K seat faces the windows rather than the aisle. This is the more common of the two cabins by a wide margin.

✅ Best seats

  • 18A, 18K — the last window row, furthest from the forward galley, with a well-placed window.
  • 11A, 11K, 12A, 12K, 15A, 15K, 16A, 16K — window-facing solo seats, all rated green.
  • Any D/G centre pair — both seats have their own aisle, so travelling as a couple costs neither of you anything.

🚫 Seats to avoid

  • 17A, 17K — the only two seats in this cabin that do not rate at the top grade. Both have two windows and both are poorly aligned with the pod, so you lean to see out. Everything else about the seat is identical to 18A and 18K, which are the better choice one row back.

Business Class — 292-seat jet (Solstys)

Thirty-two Stelia Solstys seats across rows 11, 12, 15, 16, 17, 18, 19 and 20 — eight more than the other aircraft. The cabin is staggered, so the letters alternate: rows 11, 15, 17 and 19 seat C, E, F and H, sitting inboard with the centre pair close together; rows 12, 16, 18 and 20 seat A, D, G and K, sitting outboard with the centre pair separated. All 32 seats reach an aisle directly.

✅ Best seats

  • 15C, 15H, 17C, 17H — mid-cabin, well clear of the forward galley and of the bassinet positions at the back of the cabin.
  • 16A, 16K, 18A, 18K — the outboard rows, closest to the windows.
  • 15E/15F and 17E/17F — the centre pairs that sit side by side. Take these if you are travelling together.
  • 16D/16G and 18D/18G — the separated centre pairs, if you would rather have your own space than sit shoulder to shoulder.

🚫 Seats to avoid

  • 20A, 20K — the worst seats in the cabin. There is no window beside the pod at all, just a windowless stretch of wall, and the row also sits next to a bassinet position.
  • 19C, 19H, 20D, 20G — all four sit near a bassinet position behind them, so infant noise is possible. The seats themselves are unaffected, and this is the mildest warning on the whole aircraft.

Economy — 303-seat jet (279 seats, rows 31–67)

Eight across in 2-4-2: A and C by the left windows, D–G in the centre, H and K on the right. Thirty-seven rows, with the mid-cabin lavatories taking the outboard positions of row 50 — which is why row 50 shows only four seats on the map.

✅ Best seats

  • 53A/53C and 55A/55C on the left, 53H/53K and 55H/55K on the right — the best window pairs on the aircraft. 53A, 53K, 55A and 55K each have two windows, and the whole block is mid-cabin and clear of every monument.
  • 57A, 57K, 59A, 59K, 61A, 61K — the same two-window alignment, further back and just as clean.
  • 51A, 51C, 51H, 51K — extra legroom, because the lavatory bank at row 50 forms the bulkhead ahead of them. 51H and 51K take some queuing traffic in exchange; 51A and 51C are the quieter pair.
  • 31D, 31E, 31F, 31G — the bulkhead centre block, with an unusually generous 90cm (35in) to the wall. The most legroom in the cabin, at the usual bulkhead cost.
  • 63D — the centre block narrows from row 63 back, so this seat has an empty position beside it and the spare underseat storage.

🚫 Seats to avoid

  • 36A, 36K — no usable window; the window sits well behind the seat. An ordinary row otherwise, which is what makes it easy to book by accident.
  • 49A and 49K — the sharpest trap on this aircraft. They have the best-aligned windows in the entire Economy cabin, and the lavatory bank is directly behind them, so they do not recline. The whole of row 49 rates as seats to avoid.
  • Row 48 — two rows of lavatory queuing traffic, and seven of its eight seats rate red.
  • 50D, 50E, 50F, 50G — the only seats in row 50, and they sit between the two lavatory blocks.
  • Rows 65, 66 and 67 — the rear lavatory bank. Row 67 is the last row and 67D, 67E and 67G do not recline.
  • 33A, 33K — the window sits behind the seat.

Economy — 292-seat jet (260 seats, rows 31–64)

The same 2-4-2 arrangement, three rows shorter, and with everything shifted two rows forward: the mid-cabin lavatories sit at row 48 rather than row 50.

✅ Best seats

  • 53A/53C and 55A/55C on the left, 53H/53K and 55H/55K on the right — the best seats in the cabin. 53A, 53K, 55A and 55K have two windows each, and no monument sits within several rows.
  • 41A, 41K, 43A, 43K, 45A, 45K — the same two-window alignment in the forward half.
  • 51A, 51K, 57A, 57K, 59A, 59K — the same, further back.
  • 49A, 49C, 49H, 49K — extra legroom from the row-48 lavatory bulkhead ahead. You take some queuing traffic for it, and you lose underseat storage.
  • 61D — the centre block narrows from row 61 back, so this seat has an empty position beside it.

🚫 Seats to avoid

  • Row 31 — the bulkhead, and six of its eight seats rate red. The forward lavatories open directly onto 31A, 31C, 31D, 31G, 31H and 31K; four of the eight seats are bassinet mounts; and 31A and 31K also have a badly aligned window. Only 31E and 31F escape the lavatory doors, and they still take the queue. It has the legroom and almost nothing else.
  • Row 47 — the lavatory wall is directly behind, so none of the eight seats reclines.
  • Rows 46 and 48 — the rest of the mid-cabin lavatory block. Row 48 has only its four centre seats.
  • Rows 63 and 64 — the rear lavatory bank. Row 64 is the last row with three seats and no recline.
  • 62A, 62C, 62H, 62K — 62A and 62K have the best window alignment in the cabin and sit in the rear lavatory queue. A genuine trade-off rather than a straight mistake, but worth knowing before you book it.
  • 38A, 38K — the window sits behind the seat.

The bulkhead is the difference

On the 303-seat jet, row 31 is a good bulkhead: 90cm (35in) to the wall in the centre block, no lavatory attached. On the 292-seat jet, row 31 is a bad one: the forward lavatories open onto it, half the row carries bassinet mounts, and six of the eight seats rate red. Same row number, same aircraft type, opposite verdict — which is exactly why identifying the version matters before you pay for a seat.

Known Quirks

QuirkWhat it means for seat choice
Rows 13 and 14 do not existBusiness runs 11, 12, 15, 16 on both versions. Both numbers are considered unlucky and Hainan omits them fleet-wide.
A row in the middle has only four seatsRow 48 on the 292-seat jet and row 50 on the 303-seat jet. The lavatories occupy the outboard positions, which is why the row looks broken on a booking map.
The centre block narrows near the tailFrom row 61 (292-seat) or row 63 (303-seat), the centre is three seats wide, not four. The D seat gains an empty neighbour.
Neither aircraft has Wi-FiNo Wi-Fi is recorded on either configuration. Both have Thales Avant seatback IFE.

FAQs

Q: How do I tell which A330-300 I’m getting?

A: Look at where Business ends. Row 20 means the 32-seat Solstys cabin; row 18 means the 24-seat Super Diamond one. A second check: on the Solstys jet the seat letters change every row (C E F H, then A D G K), while the Super Diamond cabin is A D G K in every row.

Q: Is one Business cabin clearly better?

A: No, and that is unusual. Both are 1-2-1 flat beds where every seat reaches an aisle directly. The Solstys jet has eight more Business seats; the Super Diamond jet has no windowless seat in the cabin. If you are choosing, avoid 20A and 20K on the Solstys jet and 17A and 17K on the Super Diamond one.

Q: I have seen the Super Diamond jet called a “338”. Is that a different aircraft?

A: No. That is a cataloguing label for the sub-fleet, not an aircraft type. Both Hainan A330-300s carry the equipment code 333. The A330-800, which really is a 338, is a different aircraft that Hainan does not fly.

Q: Which aircraft am I more likely to get?

A: Eighteen aircraft fly the 303-seat Super Diamond layout against three in the 292-seat Solstys one, so the Super Diamond jet is much the more common. Check the seat map for your specific flight rather than relying on that.

Q: Which Economy seats have no window?

A: 36A and 36K on the 303-seat jet. The 292-seat jet has none, though 31A/31K and 38A/38K have a window that sits behind the seat.

Q: Is there Wi-Fi?

A: No Wi-Fi is recorded on either A330-300 configuration. Hainan’s 787-9s do have it.
