At a glance
🎒 Personal item
One free personal item up to 14 x 18 x 8 in (35 x 45 x 20 cm) that fits under the seat in front of you.
🧳 Carry-on
Carry-on bags are NOT free on Frontier. The fee varies by route and when you add it (cheapest at booking, far higher at the gate). Max carry-on size is 24 x 16 x 10 in (including handles/wheels).
Frontier Airlines checked bag fees
| 1st checked bag (added at booking) | ~$40–$75 (varies by route) |
| Added later / at the airport | higher than booking price |
| Added at the gate | highest (often $99) |
| Overweight (51–100 lb) | +$75–$150 |
🔁 Change & cancellation
Cancel within 24 hours of booking for a full refund if you booked at least 7 days before departure. After that, standard fares are generally non-refundable; changes/cancellations may incur fees unless you bought a bundle (e.g. 'The Works') that includes free changes.
Other common fees
| Seat selection | $5–$80+ (random seat is free) |
| Carry-on bag | varies (cheapest at booking) |
How to avoid extra fees
- Add bags during booking — gate prices can be more than double.
- If you only bring the free personal item, you can fly at the lowest price.
- Compare a bundle (bag + seat + changes) vs. paying à la carte.
