Baggage fees
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyHow to use this policy
Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Leave margin instead of relying on discretionary gate behavior.
Frontier Airlines liquids policy
Consult current TSA and departure/transfer-airport screening rules, including baby-food and medical exceptions. The airline baggage allowance is separate from security permission.
Family & Infants
Infant (under 2)
A child under 2 may travel on an adult’s lap; international taxes can apply. The accompanying adult may bring an additional personal item such as a diaper bag free.
Stroller
Free gate-check.
Car seat
Free checked carriage. An FAA-approved labelled seat may be used onboard with a purchased child seat, subject to seating restrictions.
