Frontier A321ceo Seat Selection Guide (2026)
Frontier flies two different Airbus A321s and the booking page will not tell you which one you are on. Eleven are the older ceo, with 230 seats. Seventy-one are the neo, with 240. They share a row-number range and almost nothing else where it counts — and the ceo has four seats that no ultra-low-cost carrier should be giving away.
On the ceo, rows 10 and 26 have only four seats each. The A and F positions are gone, so the seats at the outside of those rows — 10B, 10E, 26B and 26E — have an empty space where the window seat should be. No neighbour on that side, and the underseat storage next to you is yours. At 28 inches of standard pitch, that is the most space anyone gets on this aircraft without paying for it.

Which A321 am I on?
Both aircraft number their rows 1 to 41, so the row range tells you nothing. These do:
| Look at… | A321ceo (230 seats, 11 aircraft) | A321neo (240 seats, 71 aircraft) |
|---|---|---|
| Rows 11 and 12 | Do not exist — the map jumps 10 to 13 | Full six-seat rows |
| Row 10 | Four seats: B, C, D, E | Six seats |
| Row 26 | Four seats: B, C, D, E | Six seats |
| Row 41 | Six seats | Two seats only — 41B and 41C |
| Rows 28 and 29 | Both full | 28F and 29A are missing |
| UpFront Plus pitch | 33in | 32in |
The one-second test: try to select a seat in row 11. If row 11 exists, you are on a neo. If the seat map goes straight from row 10 to row 13, you are on one of the eleven ceos — and rows 10 and 26 are worth grabbing.
Note that on the ceo, rows 11 and 12 are skipped numbers, not a missing section of cabin. Physically there is one row's worth of gap at the exit; Frontier simply does not use those two numbers. It means row 13 on the ceo is the eleventh row you walk past.
The best seats: rows 10 and 26
These are the two four-seat rows, and they are unusual enough to be worth spelling out. In a normal row the seats run A-B-C on the left and D-E-F on the right, with the aisle in the middle. In rows 10 and 26 the A and F seats have been removed for the overwing exits, and the remaining four seats stay exactly where they were — they do not shift outward to fill the gap.
That produces something you almost never get on an ultra-low-cost carrier:
- 10B, 10E, 26B and 26E have no seat beside them on the window side. Extra elbow and shoulder room, and the underseat space next to you is unclaimed.
- 10C, 10D, 26C and 26D are the aisle seats of those rows — normal aisle access with only one neighbour instead of two.
- Every seat in both rows is an exit-row seat, so there is more legroom than the 28-inch standard.
The catch is the usual exit-row one: no bag at your feet for take-off and landing, and you must be willing and able to operate the door. If you are, these eight seats are the best value on the aircraft by a wide margin.
The trap: 27A and 27F have legroom and no window
27A and 27F are window seats with no window. Not a badly aligned window — no window at all, just fuselage wall. They sit in an extra-legroom exit row, which is exactly why they look attractive on a seat map and exactly why people pick them. If you want the legroom of row 27, take one of the four seats inboard: 27B, 27C, 27D or 27E.
Rows 13 and 27 are the two extra-legroom rows behind the exits. Both give you space and both charge for it the same way: no underseat storage, and a tray table that folds out of the armrest rather than the seatback ahead, which makes the seat narrower. 13A and 13F have a second problem — their windows sit behind the seat, so you lean back to see out.
UpFront Plus — rows 1 to 3
Frontier sells rows 1 to 3 as UpFront Plus at 33 inches of pitch, five inches more than the standard cabin. It is the same seat as everywhere else on the aircraft with more space in front of it. Worth having — but not in row 1.
Row 1 is the worst of the three rows you can pay for. It is the bulkhead, so there is no underseat storage and the tray table lives in the armrest, narrowing the seat. On top of that, 1A, 1B and 1C have the forward lavatory ahead of them, and 1C, 1D, 1E and 1F have the galley — noise and bright light through the service. Rows 2 and 3 have the same pitch and none of it. If you are paying for UpFront Plus, pay for row 2 or row 3.
The back of the aircraft
Row 41 is the last row and none of its six seats recline. There is a wall behind it. It is also the worst row on the aircraft for two other reasons: 41A and 41F have no window at all, the same wall-only position as row 27; 41B has a lavatory door immediately beside it; and 41C, 41D, 41E and 41F back onto the rear galley.
Row 40 is nearly as bad on the right-hand side — 40C, 40D, 40E and 40F all sit against the rear galley — but at least it reclines.
Windows: which rows actually have one
The A321's window spacing does not match its seat spacing, so on a 41-row cabin the alignment drifts in and out. On the ceo:
- Best windows: 14A/14F, 25A/25F, 30A/30F, 33A/33F, 36A/36F and 39A/39F. Twelve seats with a clean, well-placed window.
- Window sits behind the seat: rows 9, 13, 21, 24, 29, 32, 35 and 38 at A and F. You can see out, but you lean back to do it.
- No window at all: 27A, 27F, 41A and 41F. Four seats, and two of them are in an extra-legroom row.
Quick picks by traveller
| You are… | Book | Why |
|---|---|---|
| After the most space for free | 10B, 10E, 26B or 26E | Exit-row legroom and an empty seat position beside you. |
| A couple | 10B/10C or 26D/26E | A four-seat row means a pair with nobody on the outside. |
| Paying for UpFront Plus | Row 2 or row 3 | Same 33in pitch as row 1, without the bulkhead, lavatory and galley. |
| Here for the view | 14A, 25F, 30A, 33F, 36A or 39F | The rows where the window actually lines up with the seat. |
| Tall, not paying extra | 27B–27E or 13B–13E | Extra-legroom rows, avoiding the windowless A and F seats. |
| Anywhere but the back | Not rows 40 or 41 | Galley, lavatory, no recline, and two seats with no window. |
Frequently asked
How do I know whether I am on the ceo or the neo?
Look for row 11 on the seat map. The ceo does not have one — it jumps from row 10 to row 13. The neo has rows 11 and 12 as normal six-seat rows. A second check: the ceo's row 41 has six seats, the neo's has two.
Which is better, the ceo or the neo?
For seat choice, the ceo — narrowly. It carries ten fewer passengers, its UpFront Plus rows are an inch deeper at 33 inches against 32, and it has eight exit-row seats in rows 10 and 26 with an empty position beside them. The neo has more of the aircraft filled in and a two-seat last row instead of six. Only 11 of the 82 A321s are ceos, so you will usually get the neo.
Does Frontier's A321ceo have WiFi or power?
No to both, and no seatback screens either. Frontier's cabins are built for cost, not connectivity. Charge before you fly.
Do the seats recline?
Frontier's slimline seats are pre-reclined and do not move, which is standard for the ultra-low-cost model. The practical consequence is that row 41 being a "no recline" row matters less here than it would elsewhere — the reasons to avoid it are the missing windows, the lavatory and the galley.
Is UpFront Plus worth paying for?
If you are tall, yes — 33 inches against 28 is a large difference, and it is the only extra-space product on the aircraft you can guarantee at booking. But take row 2 or 3 rather than row 1, and compare the price against simply picking 10B or 26E, which cost far less and give you an empty seat beside you.
Which seats have no window?
27A, 27F, 41A and 41F on the ceo. All four are marked as window seats when you book. Row 27 is the one that catches people out because it is also an extra-legroom row.
