Delta Air Lines Airbus A220-100 seat map

PUBLISHED (delta.com A220-100 aircraft page, retrieved 2026-07-14): total 109 seats; per-cabin counts Delta First 12 / Delta Comfort 20 / Delta Main 77; seat width/pitch (First 20.5 in/37 in, Comfort 18.6 in/33 in, Main 18.6 in/30-32 in); under-seat dimensions; EXITS (6), GALLEYS (2), LAVATORIES (3) with the wheelchair-accessible lavatory located behind Row 29 (seats CDE); movable armrests at all aisle seats in every cabin; and the aircraft-wide amenity set (Wi-Fi, USB in-seat power, in-seat AC power outlet, Personal Video, Satellite TV) shown identically for all three cabins. PUBLISHED (official Delta LOPA seat-map image "a220-100-dc-dom-static-desktop-mach.png"): Delta First 2-2 on columns A/B|C/D (rows 1-3); Delta Comfort 2-3 on A/B|C/D/E (rows 10-13); Delta Main 2-3 (rows 14-29); the single over-wing exit beside row 15 (both sides); the Delta Main "Preferred" seats marked with the Preferred-seat icon across the forward Main rows 15-18; the forward closet/galley/lavatory monuments; and the aft galley plus the two aft lavatories. DERIVED / RECONCILED: the marketing LOPA renders the over-wing exit row (15) with four seats (A/B/C/D present, E removed) which, with every other Main row full, would total 79 Main seats; Delta's own published accommodation table states 77 Main seats / 109 total, so this instance follows the published count and models the over-wing exit row (15) as a 2-seat row (aisle seats B and C), with both window seats (A = port over-wing exit, E = starboard over-wing exit) and the middle (D) removed for the exit passages. layoutProvenance is therefore "mixed" (row grid and all monuments read from the published LOPA; the exit-row seat count reconciled to the published table). The over-wing exit is modeled with the standard evacuation restrictions (no infants / unaccompanied minors); Delta does not print per-seat recline limits on the LOPA, so no recline restriction is asserted on the exit row itself. The last Main row (29) backs onto the aft lavatories/galley and is modeled with limited recline. The wing span (rows ~14-20) and the over_wing row attributes are read approximately from the LOPA drawing. Window alignment is "unknown" for every window seat — no A220 window-belt engineering grid exists and the LOPA does not show window positions. Recline figures are not published by Delta and are omitted. CONTEXT: this is the current Delta Comfort-expanded configuration (Comfort 15->20, Main 82->77, total unchanged at 109); the earlier 12 First / 15 Comfort / 82 Main = 109 layout is still listed on the (stale) Wikipedia fleet table and is not the configuration Delta currently publishes on its A220-100 aircraft page.
