About this cabin
Delta Air Lines' A350-900 in this configuration seats 275 (J/J/J/J/W/W/Y/Y/Y). This is our best current estimate for this layout, built mainly from secondary sources — treat exact seat-by-seat detail with a little more caution than usual. Delta Air Lines flies 2 different cabins on the A350-900 — this is one of them. This is a version lottery: the flight page will tell you which one you're actually booked on where we can determine it. This aircraft type is currently mid-retrofit, so the exact cabin can still change as more aircraft are converted.
Quick pick, by traveller
| If you're… | Pick | Why |
|---|---|---|
| Travelling solo | 3A | A window seat rated highly with nothing working against it — lean on the wall, control the shade, nobody climbing over you. |
| Travelling as a couple | 3B | This row's layout puts a genuine two-seat pair here — no middle seat exists in this group, so it's just the two of you. |
| Tall passengers | 20B | Genuine extra legroom that also still reclines — not every extra-legroom seat does. |
| Nervous flyers | 20B | Over the wing, close to the aircraft's structural centre of gravity — the smoothest ride on board when it's bumpy. |
| Trying to sleep | 3A | A window seat away from galley and lavatory traffic, so aisle lights and trolley passes are less likely to wake you. |
Seat map
Delta One (business class)
Delta One spans rows 1–11 in a 2-seat layout, 76.5in pitch and 20.46in seat width. Worth avoiding: 1B, 1C, 2B, 2C — next to galley.
Row 9 has no window suites: the second-door vestibule takes the A and D positions on Delta's own drawing, so the row is the centre pair alone.
Delta Premium Select (premium economy)
Delta Premium Select spans rows 20–24 in a 2-4-2 layout, 38in pitch and 18.5in seat width.
Delta Comfort+ (premium economy)
Delta Comfort+ spans rows 30–33 in a 3-3-3 layout, 34in pitch and 17.4in seat width. Worth avoiding: 33A, 33J, 33B, 33C — seat doesn't recline.
Delta Main Cabin (economy)
Delta Main Cabin spans rows 34–51 in a 3-3-3 layout, 31.5in pitch and 17.4in seat width. Worth avoiding: 36A, 36J, 51A, 51C — seat doesn't recline.

Seats to avoid
| Seat | Cabin | Why to avoid it |
|---|---|---|
| 1B | Delta One | A galley is directly next to you, so expect crew activity, cart noise and light throughout the flight, especially during meal service. |
| 1C | Delta One | A galley is directly next to you, so expect crew activity, cart noise and light throughout the flight, especially during meal service. |
| 2B | Delta One | A galley is directly next to you, so expect crew activity, cart noise and light throughout the flight, especially during meal service. |
| 2C | Delta One | A galley is directly next to you, so expect crew activity, cart noise and light throughout the flight, especially during meal service. |
| 33A | Delta Comfort+ | This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight. |
| 33J | Delta Comfort+ | This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight. |
| 33B | Delta Comfort+ | This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight. |
| 33C | Delta Comfort+ | This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight. |
| 36A | Delta Main Cabin | This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight. |
| 36J | Delta Main Cabin | This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight. |
| 51A | Delta Main Cabin | This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight. |
| 51C | Delta Main Cabin | This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight. |
Known quirks on this aircraft
- Seat doesn't recline (27 seats: 33A, 33B, 33C, and 24 more) — This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight.
- Often cold or draughty (20 seats: 2A, 2D, 10A, and 17 more) — Seats next to a bulkhead or door on a long-haul widebody are usually the coldest in the cabin — bring a layer for this one.
- Narrower than usual (36 seats: 30A, 30B, 30C, and 33 more) — This section is narrower than other sections of the same cabin class on this aircraft, so the seat itself will feel tighter than you might expect.
- High foot traffic (24 seats: 1B, 1C, 2B, and 21 more) — This aisle seat sits right next to a lavatory, galley or exit, so expect a steady stream of people brushing past, especially early and late in the flight.
- No underseat storage (38 seats: 1B, 1C, 10A, and 35 more) — Bulkhead and exit-row seats have nothing in front of the seat to store a bag under, so your bag must go in the overhead bin for the whole flight.
- Wing blocks the view (24 seats: 20A, 20J, 21A, and 21 more) — The wing sits directly outside this window, blocking most of the view — but you also get one of the smoothest, quietest rides on the aircraft.
Frequently asked
- How many seats does Delta Air Lines' A350-900 have in this configuration?
- 275 seats in total, arranged as J/J/J/J/W/W/Y/Y/Y. This is one specific configuration — Delta Air Lines' fleet may include other configurations of the same aircraft type, covered below.
- Is this the only cabin layout Delta Air Lines flies on the A350-900?
- No — Delta Air Lines flies 2 different cabin layouts on the A350-900 for this one. Check your specific flight's aircraft registration where possible, since booking the same route twice can put you on a different layout.
- Which seats should I avoid?
- Seat 1B in Delta One is worth avoiding: A galley is directly next to you, so expect crew activity, cart noise and light throughout the flight, especially during meal service. The full seat map marks every seat we'd steer you away from, with the specific reason for each.
- Does the A350-900 have wifi and power in this configuration?
- Delta One has excellent wifi and AC power at the seat. Power and wifi can vary by cabin on the same aircraft — check the cabin specs table above for every class.
- How confident are you in this seat map?
- This configuration is marked "provisional" — assembled from secondary sources and not yet confirmed against a primary one. See the sources and last-verified date lower on this page.
- Has a real person checked these individual seat scores?
- Not yet for this specific configuration. The scores above come from our rules engine, which reasons from real aircraft geometry, but they aren't marked as human-verified until someone has actually reviewed the unusual ones — see the verification section below for the current status.
