Frontier Airlines Checked Baggage: Fees, Size & Weight (2026)
Frontier charges for checked bags with dynamic, route-based pricing — the first bag often runs $40 to $75, cheapest when prepaid well before departure and most expensive at the airport or gate. Frontier's weight limit is 40 lb, lower than the 50 lb standard everywhere else, so overweight fees hit sooner.
Fees vary by route and when you pay — ranges below are indicative; weight and size limits are fixed.
| Bag | Prepaid | At airport |
|---|---|---|
| First checked bag | $40 to $75 (dynamic — cheapest prepaid 6+ days before departure, most expensive at the airport/gate) | $75 |
| Second checked bag | higher, dynamic | higher |
| Third+ bag | dynamic, higher | |
