Peta kursi JetBlue Airways Airbus A220-300

Single-class all-Core A220-300. PRIMARY-SOURCED COUNTS: 140 seats, 2x3 layout, 18.5 in (A/C side) / 19 in (D/E/F side) seat width, marketed 18.6 in (widest single-aisle / widest in JetBlue fleet), 10.1-inch 1080P HD seatback screens, ViaSat-2 Fly-Fi, AC+USB-A+USB-C power (JetBlue press release 2021-01-12). 'Six rows of Even More Space' (press release) = 30 EvenMore seats across six 5-abreast rows; remaining 110 are standard Core. DERIVATIONS (JetBlue publishes no per-seat A220 map outside a booking session, and competitor seat-map sites are barred by policy) — layoutProvenance derived_from_counts: (1) EvenMore front block placed at rows 1-4 because jetblue.com/help/seats lists 'Reserved rows: Row 5' as the first non-EvenMore (Core) row and 'Fixed armrests: Row 1' as the front bulkhead (same pattern the help page uses for other JetBlue types). (2) The remaining two EvenMore rows are the over-wing area rows 12-13; row 12 is modeled as the single over-wing exit row because help/seats lists 'No recline: Row 11' (the fixed row immediately ahead of an exit) and JetBlue states EvenMore exit seats themselves still recline. (3) 'Limited recline: Row 28' (help/seats) = the last row ahead of the aft galley/lavatories. (4) Column letters A/C (2 side) and D/E/F (3 side) are taken from help/seats ('seats AC' / 'seats DEF'); the 'B' letter is unused. (5) Wing span (rows ~12-18), over_wing row attributes, and all lavatory/galley/door monuments are structural estimates for a 140-seat A220-300; JetBlue does not publish A220 lavatory positions. All seat-level ratings/flags are structural inference except the recline restrictions (rows 11, 28) and fixed armrests (row 1), which are from help/seats. UNSOURCED MEASUREMENTS (marked unsourced): Core pitch (JetBlue markets 'most legroom in coach' but publishes no A220 number) and the EvenMore minimum pitch ('up to 38 in' is published; the floor is not). CONFLICT: Wikipedia's JetBlue fleet table lists Y+ (Even More Space) as 25 and Y as 115; JetBlue's own press release ('six rows' = 30) is preferred as the primary source and drives the 30/110 split — see the caveat on the Wikipedia source. NO A220 window-belt engineering grid exists, so windowGridType is omitted and every window seat is windowAlignment 'unknown'. E190 retirement completed 2025-09-09, finishing JetBlue's A220 transition (Wikipedia, timeline only).
