Frontier Airlines Carry-On Rules: Fees & Free Options
Frontier Airlines: Personal item, paid carry-on and the bag shown on your booking.
Every fare includes one 18 × 14 × 8 in (45.72 × 35.56 × 20.32 cm) personal item. A purchased or qualifying bundled overhead bag may measure 24 × 16 × 10 in (60.96 × 40.64 × 25.4 cm). The current Bag Options page gives a 35 lb (about 15.9 kg) cap for both; handles, wheels and straps count.
Physical fit and fare inclusion are separate. A 55 × 40 × 20 cm bag can fit the overhead box while exceeding the free personal-item box. Select Basic or the actual purchased add-on in the checker. A membership name or a past flight is not proof of the bag entitlement on this reservation.
Measure the packed outside and weigh the bag. Leaving weight blank cannot confirm the published weight cap. The airline quotes baggage prices for the trip and purchase stage; this guide does not promise one universal gate price. An adult with a lap infant may bring an additional personal item such as a diaper bag free; international infant taxes can apply.
