Frontier Checked Baggage: 40 lb Limit, Fees and Booking
Frontier standard checked bags: 40 lb and 62 linear inches. Check the current price, excess brackets and bag inclusion for your reservation.
Frontier's current standard checked-bag allowance is 40 lb (about 18.1 kg) and 62 linear inches (157.48 cm). Measure the outside length + width + height. A 50 lb suitcase exceeds this standard allowance even if it is normal on another airline. Confirm the bag benefit and price on the actual reservation.

Compare the actual booking
Record the departure and destination, travel and ticket dates, fare/bundle, number of bags, packed measurements and weight, purchase stage and currency. Open Bag Options or My Trips for the bag price and any included benefit. Compare the same bags in both directions. A low base fare or discount membership does not establish what this reservation includes.
A 45 lb bag within 62 linear inches falls in the published 41–50 lb bracket; the $75 addition does not include the standard bag price. A 39 lb bag with 70 linear inches passes the standard weight cap but reaches the published oversize bracket. These are arithmetic examples, not purchased quotes or physical tests.
Before check-in
Weigh the packed bag again after adding shoes and toiletries. Do not rely on an unverified product name to decide whether a cabin alternative fits. Frontier's free personal item and paid overhead bag have different dimensions; use the cabin checker for those roles, not to price a checked bag. See the checked-fee comparison method to compare complete trips.
