Frontier Airlines — official cabin limits
| Allowance | Max dimensions (inches — the airline's own figure) Second line: our conversion | Max weight |
|---|---|---|
| Free personal item | 18 × 14 × 8 in ≈ 45.7 × 35.5 × 20.3 cm | 35 lb ≈ 15.8 kg |
| Carry-on | 24 × 16 × 10 in ≈ 60.9 × 40.6 × 25.4 cm | 35 lb ≈ 15.8 kg |
How to read these numbers — Frontier Airlines publishes these limits in inches — the unit its airport sizers are built to. The centimetre figures are our own conversion, always rounded down. Airlines that print both units often print two figures that don't agree with each other — sometimes looser, sometimes stricter. When they disagree we go by the airline's own unit and round the other one down. Packing to our number keeps you inside the real limit.
What to expect
Frontier gives every ticket one free personal item of 18 × 14 × 8 in (45.7 × 35.5 × 20.3 cm), and on the base fare that is the only bag included. The overhead carry-on is larger than most, 24 × 16 × 10 in (60.9 × 40.6 × 25.4 cm), but it is a paid add-on unless you buy a bundle or hold Elite Gold status or above. Both bags must weigh no more than 35 lb including handles, wheels and straps, a limit most US carriers never publish. Frontier checks the size at boarding, so measure at the widest point.
Soft bag vs hard case
Frontier's carry-on allowance is roomy at 24 × 16 × 10 in, but the 35 lb weight cap is the real ceiling: a rigid case spends that weight before you have packed anything. The wheels, handles and straps all count toward the limit, and Frontier checks bags at the gate. A soft, frameless bag compresses into the sizer, where a hard shell sitting a few millimetres over gets pulled.
Boarding tips
- The personal item is free on every fare; the overhead carry-on is not, so on the base fare you either pack into the personal item or pay for the carry-on.
- Frontier does not publish a fixed carry-on price. It is cheapest added when you book and most expensive at the airport, so add bags in advance through My Trips.
- A bundle (Economy, Premium or Business) or Elite Gold status and above includes the carry-on, and the bundle is often cheaper than the bag alone.
- Both bags share a 35 lb limit including wheels and handles. There is no separate lighter allowance for the personal item.
- If the overhead bins fill up, Frontier gate-checks the carry-on at no extra charge.
