Frontier Airlines allows a carry-on up to 24 x 16 x 10 in, measured including wheels and handles. Put your own bag's measurements in below — it opens with Frontier Airlines's own limit filled in.
| Carry-on maximum | 24 x 16 x 10 in (including wheels and handles) |
| Personal item | 18 x 14 x 8 in |
| Cabin weight limit | 35 lb (15.9 kg) |
| Is the carry-on free? | No — Frontier Airlines charges for it |
| If it does not fit | Paid at the gate at the highest price tier. |
Frontier CHARGES for the full-size carry-on. Only the personal item is free. It is cheapest bought during booking and most expensive at the gate.
Both allowances include handles, wheels and straps in the measurement.
Frontier Airlines's 24 x 16 x 10 in works out to about 3840 cubic inches (62.9 litres) of cabin allowance, which ranks 2 of 22 among the airlines we have verified, about 30% more than the median carrier.
The same 24 x 16 x 10 in limit is used by 1 other airline here — Southwest Airlines. A bag bought to that spec travels widely, which is exactly why it is the size most luggage is sold in.
Nothing we track allows a larger carry-on, so a bag that fits here is at the generous end of what any airline permits.
Common bag sizes measured against Frontier Airlines's published limit. Every figure includes wheels and handles, which is where most bags lose.
| Bag | Size | On Frontier Airlines | Why it matters |
|---|---|---|---|

| Compact 21-inch | 21 × 14 × 9 in | Fits, 1 in spare | A common step down |
| European cabin bag | 21.7 × 15.7 × 7.9 in | Only just — 0.3 in spare | Sized to 55 x 40 x 20 cm |
| Underseat tote | 17 × 13 × 8 in | Fits, 2 in spare | Typical personal-item size |

If it does not fit, the bag gets checked — and on Frontier Airlines a first checked bag costs $29–$79 each way. On a return trip that is roughly $58–$158 for a bag you meant to carry on.

Frontier Airlines allows a personal item up to 18 x 14 x 8 in alongside the 24 x 16 x 10 in carry-on. Only the personal item is free — the overhead bag is charged, so travelling on the under-seat allowance alone is how you fly Frontier Airlines without paying for baggage.

Frontier Airlines publishes a cabin weight limit of 35 lb (15.9 kg). 35 lb limit on BOTH the carry-on and the personal item — unusual, and easy to miss.
Up to 18 x 14 x 8 in. Included free with every fare, up to 35 lb.
Yes. Frontier Airlines measures the bag including wheels, handles and any external pockets, which is why a bag sold as “22 inch” can still measure over.
