JetBlue A321 Domestic Seat Selection Guide (2026)

Flying JetBlue but not sure which aircraft? See all JetBlue seat maps: JetBlue flies six cabin layouts, and the seat maps differ.

The version lottery: where Even More Space sits

JetBlue flies two all-economy A321s that sell identically — 200 seats, 42 of them Even More Space — and put those 42 seats in different places. If the aircraft swaps, an Even More Space seat number on one can be an ordinary Core seat on the other.

The fastest tell is on the seat map at booking. If the orange Even More Space block reappears at rows 16–18, you are on the neo. If it appears as single rows at 10 and 23, with four-seat rows directly in front of each, you are on the ceo.

BlueFirst is about to change both

JetBlue is fitting a domestic first-class cabin, BlueFirst, to every A320-family and A220 aircraft that does not have Mint. The seats are Collins MiQ recliners in a 2-2 layout at the front of the cabin, with up to about 37in of pitch. The first aircraft goes into modification on 21 September 2026; roughly a fifth of the non-Mint fleet is due to be done by the end of 2026 and most of the rest during 2027.

How many BlueFirst seats the A321neo gets has been reported two ways — 12 in one account and 16 in another — and JetBlue has not published the converted seat map for this type. What is consistent across the coverage is that Core legroom tightens to about 30in on converted aircraft. On the A320, the one type where the converted plan has been reported in full, Even More Space loses twelve seats to make room.

How to tell if your aircraft has been converted: a converted aircraft shows 2-2 seating in its first rows. If you see that, the row numbers in this guide no longer apply. If the whole seat map is 3-3 from row 1, they do. Our BlueFirst guide covers the new cabin.

A321neo: the trap is row 24

A lavatory on the left and a snack galley on the right stand between rows 23 and 24 in the middle of the neo’s cabin. That puts a bulkhead in front of row 24, so all five of its seats have bulkhead legroom — and none of them is Even More Space. They sell as Core. On a booking map they look like the best free seats on the aircraft.

Most of them are not. There is no 24A — the row starts at B — and the seats that remain each have a catch:

If you want the legroom without paying for it, 24D and 24E are the two defensible seats in the row. If you are paying anyway, Even More Space at rows 16–18 is better in every way.

The same lavatory punishes the rows in front of it. 22A–22C and 23A–23D back onto it and are rated red, and all of row 23 has limited recline because the wall is directly behind.

A321neo: every Even More Space row is the same row

The neo has six Even More Space rows behind the bulkhead — 2, 3, 4, 16, 17 and 18 — and the cabin plan marks all six at 34–35in. There is no longer-legroom pair among them. Rows 16 and 17 sit at the overwing exits; row 18 is directly behind and gets the same legroom without the exit-row restrictions.

All eighteen seats in rows 16, 17 and 18 are rated green, which makes that block the best on the aircraft. In the forward block, rows 2 and 4 are green across; in row 3 the middle four are green and 3A and 3F have their window set behind the seat.

Row 1 is the bulkhead: legroom, but no underseat storage, the tray table and screen folded into the armrest, the forward lavatory in front of 1A–1C and the galley in front of 1C–1F. All six are yellow. It is Even More Space you would pay the same for as row 2, and row 2 is better.

A321neo: the back of the cabin

Row 34 is three seats — 34A, 34B and 34C — against the rear lavatories. None reclines, all three are red, and 34A has no window. 33D, 33E and 33F catch the rear galley.

For a Core window seat without Even More Space, take 25F, 27A, 27F, 29A or 29F in the back half, or 7A, 7F, 9A, 9F, 11A, 11F, 13A or 13F in the front half. All are rated green. Avoid 32A and 32F, which have the glass set behind the seat.

A321ceo: the exit rows are not the best seats

On the ceo, the Type C doors at positions 2 and 3 take the window seats out of the rows beside them, which is why rows 9 and 22 are only four seats wide — B, C, D and E. Rows 10 and 23 sit behind those doors, carry the door legroom, and are sold as Even More Space.

They are not the seats to buy. All twelve seats in rows 10 and 23 are rated yellow: no underseat storage, and the tray table and screen live in the armrest, which narrows the seat. Rows 2 to 5 are the best seats on the ceo — marked about 35in, twenty-four seats, every one rated green, with a normal tray table and somewhere to put your bag.

The other green seats are the four-seat rows themselves. 9B–9E and 22B–22E are all rated green: every one has an aisle, and 9B, 9E, 22B and 22E have an empty window position beside them instead of a neighbour. They are Core seats.

23A and 23F do have a window. It sits behind the seat, so you lean back to see out, but they are not windowless seats. Sixteen other ceo window seats have the same misalignment: 6A/F, 8A/F, 16A/F, 18A/F, 20A/F, 24A/F, 26A/F and 28A/F.

At the back, 33A–33C and 34A–34D are red against the rear lavatories, and nothing in row 34 reclines.

Quick-pick summary

Frequently asked questions

Which JetBlue A321 seat has the most legroom?

On the A321neo, every Even More Space row behind the bulkhead — 2, 3, 4, 16, 17 and 18 — is marked at 34–35in, so no single row beats the others. Rows 16–18 are the best because all eighteen seats are rated green. On the A321ceo, rows 10 and 23 have the most room in front of you but are bulkhead seats with narrower seats and no bag space; rows 2–5 are the better buy.

Is row 24 on the JetBlue A321neo a good seat?

Mostly no. All five seats have bulkhead legroom and are sold as Core, but 24B and 24C sit right against the mid-cabin lavatory, 24F has no window, and 24D and 24E have no underseat storage. 24D and 24E are the only two worth taking, and only if you want the legroom without paying for Even More Space.

How do I tell the A321neo from the A321ceo when booking?

Look at the orange Even More Space rows. Rows 16–18 in orange means the neo. Single orange rows at 10 and 23, with four-seat rows directly ahead of them, means the ceo.

What is BlueFirst, and does it affect this aircraft?

BlueFirst is JetBlue’s new domestic first class: 2-2 recliners at the front of every non-Mint aircraft, fitted from 21 September 2026 and mostly complete during 2027. A converted A321 has a different seat map, less Core legroom (about 30in, reported) and fewer Even More Space seats. If your seat map starts with 2-2 rows, this guide’s row numbers no longer apply.

How many all-economy A321neos does JetBlue have?

Sixteen, at 31 December 2025. JetBlue also flies A321neos with Mint — covered in our A321 Mint guide — and they are a different cabin.

Is Wi-Fi free on the JetBlue A321?

Yes. Both versions have free Viasat satellite Wi-Fi and seatback screens with DIRECTV.
