Frontier Airlines carry-on dimensions and bag size

The maximum Frontier Airlines carry-on size is 24 x 16 x 10 inches, which works out to 61 x 41 x 25 cm. These measurements include wheels, handles, and any external pockets. Gate sizers on Frontier Airlines match the published limits closely, so a bag marketed as "22 inch" can fail if its wheels push the total past 24 inches. Always measure your bag packed, not empty.

Frontier Airlines carry-on weight limit

Frontier Airlines limits carry-on bags to 16 kg (35 lb). Most domestic check-in counters do not weigh carry-ons, but gate agents can pull bags that look heavy. If your bag is over the limit, expect to be asked to check it, sometimes at a higher gate-check fee.

Does Frontier Airlines charge for carry-on bags?

Yes. Frontier Airlines charges for carry-on bags on most fares, starting at around $59 when added at booking. Fees climb at every stage: online, airport kiosk, ticket counter, gate. The personal item stays free on every fare. Basic Economy fares on Frontier Airlines are the ones where carry-on fees apply most aggressively, since the fare excludes the overhead-bin bag by default.
