Frontier Baggage Policy: Personal Item, Carry-On and Checked Bags
Compare Frontier bag categories: free 18×14×8 in personal item, paid 24×16×10 in carry-on and 40 lb checked bag. Verify the booking price.
Frontier includes one personal item with every fare. An overhead bag or checked bag requires the applicable purchased allowance or included booking benefit. The size of the free personal item is 18 × 14 × 8 in, not 14 × 10 × 8 in.
Pick the bag category first
| Category | Published dimensions / weight | What to verify |
|---|---|---|
| Personal item | 18 × 14 × 8 in; up to 35 lb | Under-seat fit; handles, wheels and straps count |
| Overhead carry-on | 24 × 16 × 10 in; up to 35 lb | Purchased bag or eligible bundle/benefit in this reservation |
| Standard checked bag | 62 linear inches; up to 40 lb | Base price, any included bag, excess charges and route restrictions |
The current Bag Options page publishes the 35 lb cap for the personal item as well as the carry-on. Prices are higher at the airport; use the actual flight and purchase stage to check the amount. Old universal $39/$75/$99 tables and automatic free-bag claims tied to a discount membership are not reliable booking quotes.
A bag can fit and still need an add-on
A 55 × 40 × 20 cm bag is within the overhead dimensions, but is larger than the included personal-item box. Check it with Basic, then choose an add-on only if you purchased one. A 43 × 33 × 18 cm bag is within the personal-item dimensions; weigh it and check the packed protrusions too. These examples apply the published limits without claiming a physical test.
Benefits and family exceptions
Check the fare/bundle or elite benefit displayed on the booking rather than assuming that a subscription or earlier trip includes the same bags. Adults with a lap infant may bring an additional personal item such as a diaper bag free; international infant taxes can apply. Strollers and car seats may be checked free, while cabin use has separate fit and approval rules.
For weight and size excess on a checked bag, read the Frontier checked-baggage guide. For the total journey cost, use the checked-fee comparison checklist.
