Delta Airbus A220-100 Seat Selection Guide (2026)
Delta's Airbus A220-100 is the smaller of the airline's two A220 variants — 109 seats across 45 aircraft, with a 2-3 economy layout that gives you only one middle seat per row. It is one of the best narrowbodies flying, but the -100 has a much smaller Comfort+ cabin than the -300 and a rear block that is genuinely worth avoiding.

- Wi-Fi: Viasat Ka-band — free for SkyMiles members
The A220-100 vs A220-300 Lottery
Delta operates both A220 variants and the booking engine labels them separately — but plenty of travellers book "an A220" without checking which one, and in economy the two aircraft are not equivalent.
| A220-100 | A220-300 | |
|---|---|---|
| Fleet | 45 | 36 (growing) |
| Total seats | 109 | 130 |
| First Class | 12 (rows 1-3) | 12 (rows 1-3) |
| Main Cabin | 97 (rows 10-29) | 118 (rows 10-33) |
| Comfort+ seats | 15 (rows 10-12) | 43 (rows 10-18) |
| Standout economy seat | 15C / 15D (exit row) | 17B (solo seat) |
| Windowless window seats | 14A, 14E, 15A | 19A, 19E |
If you hold Delta status and are hoping for a complimentary Comfort+ upgrade, the A220-300 gives you nearly three times the odds. On the -100 there are only 15 Comfort+ seats and they clear early.
How to tell which one you're on: the seat map is the giveaway. The A220-100 economy cabin ends at row 29; the A220-300 runs to row 33. If Comfort+ stops at row 12, it's the -100.
First Class — 12 seats, rows 1-3
Collins Aerospace MiQ recliners in 2-2: A-B on the left, C-D on the right. For a 109-seat aircraft this is a genuinely good domestic First cabin — 37" pitch and 20.5" width are both at the top of the US domestic range, and the 13.3" screens are larger than most mainline narrowbodies.
Pitch: 37" · Width: 20.5" · Recline: 5" · Screen: 13.3" HD touchscreen · Power: 110V AC + USB-A · Armrest: adjustable on the aisle side only
✅ Best First Class seats
- 3A and 3D — last row of First, furthest from the forward galley, with two windows lined up alongside each seat.
- 2A and 2D — mid-cabin windows, no galley noise, no bulkhead compromise. The safe default.
🚫 First Class seats to avoid
- 1C and 1D — the forward galley is directly ahead. Service noise and light, with nowhere to escape it in a cabin this small.
- 1D specifically — a plugged window section alongside makes the view materially worse than any other window seat.
- 1B — the bulkhead ahead is not full width, so you get the restrictions without meaningful extra legroom.
Delta Comfort+ — 15 seats, rows 10-12
This is the smallest Comfort+ cabin on any Delta mainline aircraft: fifteen seats, three rows, 34" pitch against 31-32" in standard Main Cabin. Same Collins Pinnacle seat, same 10.1" screen — you are buying legroom and earlier boarding, nothing else.
✅ Best Comfort+ seats
- 11A and 11E — windows perfectly aligned to the seat, no row 10 bulkhead penalty. 11A is the pick: it sits in the A/B pair, so one neighbour instead of two.
- 10A, 10B and 10E — bulkhead legroom while keeping normal underseat storage and a normal tray table.
🚫 Comfort+ seats to avoid
- 10C and 10D — no underseat storage, tray table and screen in the armrest (which narrows the seat), and no bag at your feet during taxi, takeoff or landing.
- 12A and 12E — the window sits behind the seat position; you have to lean back to see out.
- 10D, 11D, 12D — the only middle seats in Comfort+. Extra legroom does not fix the middle of a triple.
Main Cabin — 82 standard seats, rows 13-29
The 2-3 layout is the A220's best feature and the strongest reason to pick it over a 737 or A320. There is one middle seat per row instead of two, and the left-hand A/B pair — a window and an aisle with nobody to climb over — is the most sought-after economy seating on any Delta narrowbody.
Pitch: 31-32" · Width: 18.6" · Recline: 3" · Screen: 10.1" HD touchscreen · Power: 110V AC + USB-A · four-way headrest and personal air vent at every seat
✅ Best Main Cabin seats
- 15C and 15D — the exit row on the right and the best economy seats on the aircraft, around 36" of pitch. There is no 15E, so 15D has an empty seat position beside it — extra shoulder room and the underseat space next to you.
- 15B — exit-row aisle on the left, full exit legroom, and only one neighbour.
- 22E — the best standard-pitch window in the cabin: properly aligned, far enough forward to avoid rear-galley traffic.
- Clean A seats, rows 16-25 — 17A, 19A, 21A, 23A and 25A are all window seats with a single neighbour and no rear-cabin penalties.
🚫 Main Cabin seats to avoid
- Rows 28 and 29 — the entire block. Both back onto the rear lavatories with the galley immediately behind: queue, door, noise, light and smell for the whole flight. Row 29 has no A or B seats.
- 27A and 27B — directly beside the rear lavatory on the left, frequently sold as if they were normal seats. 27D and 27E are the milder right-hand equivalent.
- 14A, 14E and 15A — sold as window seats, but the window sits forward of the seat and there is effectively nothing at your shoulder.
- Row 14 generally — recline is restricted because exit row 15 behind needs a clear path.
- 16E — no 15E ahead sounds like a win, but it means no underseat storage and a tray table in the armrest.
- 12A, 18A, 20A, 22A, 24A, 26A and 26E — window set behind the seat position; you will be craning to see out.
- Every D seat — the only middle seat on the aircraft.

FAQ
Does the Delta A220-100 have seatback screens?
Yes — every seat in both cabins. First Class gets 13.3", Main Cabin and Comfort+ get 10.1", both HD touchscreens, plus streaming to your own device. This is one of the few Delta narrowbodies with seatback IFE fitted fleet-wide with no exceptions.
Why does the A220 have only one middle seat per row?
The fuselage is narrower than a 737 or A320 but wider than a regional jet, so Airbus specified 2-3 rather than 3-3. Only 20% of economy seats are middles, against 33% on a 737 — and the two-seat A/B side is why frequent flyers go out of their way to book this aircraft.
Which are the best economy seats on the Delta A220-100?
15C and 15D in the exit row, at roughly 36" of pitch. With no E seat in row 15, 15D has an empty seat position beside it. If the exit row is gone, 11A in Comfort+ or 22E in the standard cabin are next.
How many Comfort+ seats are on the A220-100?
Fifteen, in rows 10-12 — the smallest Comfort+ cabin in Delta's mainline fleet, at 34" pitch. The A220-300 has 43 Comfort+ seats across rows 10-18 and much better upgrade odds.
Which seats should I avoid on the Delta A220-100?
Rows 28 and 29 without exception — they back onto the rear lavatories and galley. 27A and 27B sit beside the rear lav on the left. And if you are booking a window for the view, avoid 14A, 14E and 15A.
Is there really a window in the lavatory?
Yes. One of the two rear lavatories on every Delta A220 has an exterior window — a small thing, but it makes the rear lav noticeably less claustrophobic.
Is the Wi-Fi free?
The A220 fleet carries Viasat Ka-band satellite Wi-Fi, the faster of Delta's two systems and reliable enough for browsing and light streaming. It is free for SkyMiles members on most domestic flights.
