China Eastern Comac C919 Seat Selection Guide (2026)

First, the row numbers: 6, 7, then 31

Before anything else, get your bearings, because the C919 numbers its cabin unlike almost any aircraft you have flown in Europe or North America.

Business is rows 6 and 7. Economy is rows 31 to 56. There is no row 1 through 5, and nothing at all between 8 and 30. The jump is not a mistake on the seat map and it does not mean seats are missing — it is simply how Chinese carriers number their cabins. All 164 seats are accounted for in those 28 rows.

The lettering is different too. Economy runs A B C on the left and J K L on the right. Business is A C on the left and J L on the right. There is no D, E, F, G or H seat anywhere on this aircraft. If you have been given a seat number containing one of those letters, it is not for this aircraft.

Book row 40, not row 39

This is the one that costs people. The C919 has two overwing exits, one after row 38 and one after row 39, which leaves row 39 sandwiched between them. That has a consequence most seat maps will not show you.

Row 39 has the extra legroom and cannot fully recline. With an exit behind it as well as ahead, the path has to stay clear, so 39A, 39B, 39K and 39L are all flagged. On top of that, 39A and 39L have a window that sits forward of the seat — you lean ahead to see out, and the view from both rates poor.

Row 40 has the same extra legroom, full recline, and properly aligned windows. All six seats rate well. It is one row further back, it is usually the same price or cheaper, and there is no argument for taking row 39 over it.

• 40C and 40J are the best seats in economy — extra legroom, direct aisle access, full recline, nothing against them.
• 40A and 40L are the same deal with a working window.
• 40B and 40K are the best middle seats on the aircraft: extra legroom, and the wider centre seat.
• If row 40 is gone, 39C and 39J are the only two seats in row 39 without a recline restriction.
• Exit-row rules apply in both rows — nothing on the floor for take-off and landing.

Row 31 is a bulkhead that gives you less room, not more

Row 31 is the first row of economy. It sits against a bulkhead, it is the row nearest the front, and on most aircraft that combination is worth paying for. Here it is the opposite.

The wall sits about 42 to 43cm — 17 inches — ahead of the seat, explicitly less legroom than a typical bulkhead. That is not extra space; it is a wall closer to your knees than the seatback in front of you would have been. All six seats in the row are flagged, and there are two further catches:

• No underseat storage. There is no seat in front to put a bag under, so everything goes in the overhead bin for take-off and landing.
• The tray table is in the armrest, which makes the armrest thicker and the seat effectively narrower than the same seat further back.

There are two mitigations worth knowing. 31A and 31L have excellent window alignment — among the best on the aircraft — which is the only real argument for the row. And the bulkhead does not run the full width: it covers about 65% of the row on the right and 70% on the left, so 31C and 31J get some extra foot room on their outboard side. 31J is the pick of a poor row.

Business class — eight seats, two rows, and one side is better than the other

Business is rows 6 and 7 in a 2-2 layout, lettered A C | J L. Eight seats. Half of them have direct aisle access, which is simply what 2-2 means: the window passenger steps past the aisle passenger. Secondary reporting puts the pitch at roughly 38 to 42 inches; no measured figure is published.

The split that matters is left versus right. The forward galley sits directly ahead of the right-hand pair.

• Best: 6A and 6C. Front row, extra room ahead at the bulkhead, and clear of the galley. 6A has two windows at the position.
• Avoid 6J and 6L if you can. They have the same bulkhead legroom, but the galley is directly in front — expect noise and bright light through the whole service. These are the only two flagged seats in the cabin.
• Row 7 is unremarkable in the best sense — no bulkhead legroom, but nothing flagged against any of the four seats, and far enough back to be clear of the galley. If the front row is gone, 7A or 7L is a perfectly good outcome.

The rest of economy — what to take and what to skip

The best of the standard seats

• 50A and 50L — the best window seats in economy. Excellent alignment, well clear of the rear lavatories, and no more expensive than any other standard seat.
• Rows 32 to 37 — the quiet stretch. Nothing flagged anywhere in six consecutive rows, forward in the cabin, well clear of both the galley and the lavatories.
• 38C and 38J — worth a specific mention. The window and middle seats in row 38 lose their recline to the exit behind, but the two aisle seats do not. Same row, no penalty.

The back of the aircraft

The rear twelve seats are the worst on the C919 and it is not close. Every seat in rows 55 and 56 is rated avoid — all twelve are immediately adjacent to the rear lavatory, with the noise, the odours and the queue that come with it.

• Row 56 is worse than row 55. It is the last row, the fuselage has tapered so the seats are narrower than the cabin standard, and the rear galley is alongside 56B, 56C, 56J and 56K as well.
• Row 54 is the warning row. Not against the lavatory door, but close enough that all six seats are flagged for queuing traffic and noise.
• 42A and 42L — the window is set behind the seat, so the view is restricted. Rows 41 and 43 are the better windows there.

The middle seat is the widest seat in the row

One genuinely unusual thing about the C919 cabin. Reporting on the aircraft's design says the centre seat in each economy row is built about 1.5cm wider than the window and aisle seats either side of it — a deliberate attempt to take some of the sting out of the least popular position on any narrowbody.

Treat that as Comac's design claim rather than a measured figure: no seat widths are published for this aircraft at all. But if you are travelling as a three and someone has to take the middle, this is one of the few aircraft where that seat is not straightforwardly the worst of the three. 40B and 40K — wider centre seat, extra legroom, full recline — are the best middle seats on the jet.

What the C919 does not have

Two absences worth knowing before you board, both recorded rather than inferred:

• No WiFi. The aircraft is listed as having no connectivity at all.
• No in-flight entertainment recorded — no seatback screens, and no streaming service listed either. Bring your own device and your own content, and download before you fly.

Neither is unusual for a short-haul domestic narrowbody in China, but both are worth planning around on a three-hour sector.

Quick picks by traveller

One layout — but check the airline

There is no version lottery here. There is a single C919 configuration for China Eastern across 17 aircraft, so every row number in this guide holds on every China Eastern C919 you can be booked onto. That is unusual and it makes this a straightforward aircraft to plan for.

The caveat is the operator, not the aircraft. Air China and China Southern also fly the C919, in their own cabin layouts. The row numbers and seat counts in this guide are China Eastern's and should not be carried across to another carrier's C919 — check the seat map for the airline you are actually flying.

Frequently asked questions

Why does the C919 have no rows 8 to 30?

It is a numbering convention, not missing seats. China Eastern numbers Business as rows 6 and 7 and starts Economy at row 31. All 164 seats are present across those 28 rows. Chinese carriers commonly number cabins this way, and the same pattern appears across much of China Eastern's fleet.

Why is there no seat D, E or F?

The C919's economy rows are lettered A B C on the left and J K L on the right, and Business is A C | J L. D, E, F, G and H are not used at all. The aisle seats are C and J; the windows are A and L.

What is the best seat on the China Eastern C919?

6A in Business — front row, bulkhead legroom, two windows, and clear of the galley. In economy, 40C and 40J: extra legroom from the exit ahead, direct aisle access, and full recline. For a window, 50A or 50L.

Which seats should I avoid on the C919?

All of rows 55 and 56 — twelve seats hard against the rear lavatory, with row 56 narrower as well and the galley alongside four of its seats. Row 31, where the bulkhead sits 17 inches ahead and there is no underseat storage. 6J and 6L in Business, directly behind the galley. And 39A and 39L, which have the exit-row legroom but a window set forward of the seat and no full recline — row 40 fixes both.

Does the China Eastern C919 have WiFi or seatback screens?

Neither. There is no WiFi on this aircraft and no in-flight entertainment system of any kind — no seatback screens and no streaming service listed. Download what you want to watch before you board.

Is the C919 comfortable compared with an A320 or 737?

Dimensionally it is in the same class. Secondary reporting puts C919 economy at about 30 inches of pitch and 18 inches wide, which is competitive with the narrowbodies it is built to replace; no pitch or width figures are published for the type, so treat those as manufacturer and press figures rather than measured ones. The one genuine design difference is the centre seat, which is built slightly wider than the seats either side of it.
