What is Frontier Airlines's checked bag weight and size limit?
Every bag on Frontier Airlines must weigh 50 lbs / 23 kg or less and measure no more than 62 linear inches (length + width + height) to avoid surcharges. Both limits apply independently — a light bag that is too large still triggers the oversize fee.

How do bag fees affect my Leave-By Time?
Checking a bag adds 20–30 minutes to your airport buffer compared to carry-on only. You need time to join the bag-drop queue, hand off the bag, and collect your receipt before you can head to the TSA checkpoint. That window sits before security — not inside it — so it shifts your Leave-By Time at home earlier, not just your airport arrival.
Use the Leave-By Time calculator — enter your flight, mark that you are checking a bag, and the calculator adds the bag-drop counter step so you leave home with exact numbers instead of a rough guess.
Things to know before you check a bag on Frontier Airlines
- Frontier's overweight fee (51–99.99 lbs) increased to $129 per bag per direction for bookings on or after April 4, 2026 (was $100); bags at or above 100 lbs are not accepted.
- All carry-on, checked bag, and oversize fees are fully dynamic — prices vary by route, travel date, and how early you purchase; Frontier's Bag Price Checker at flyfrontier.com is the only reliable source for actual fees.
- Ski and golf equipment are exempt from the oversize fee if flagged as sports equipment; only the overweight fee ($129) applies if over 50 lbs.
