How Frontier baggage actually works
The essentials in plain language. Your exact allowance depends on your fare, bundle and status.
Every Frontier ticket, including the base fare, includes one personal item, up to 18 x 14 x 8 in, at no charge. It has to fit under the seat in front of you; Frontier measures and enforces this at the gate.
This is the fact that catches people out. A carry-on, up to 24 x 16 x 10 in, is not part of Frontier's base fare. You either buy it as an add-on or it comes included the moment you're on an Economy, Premium or Business bundle, or hold Elite Gold status or above.
A standard checked bag can weigh up to 40 lb, or up to 50 lb if it's part of the Business bundle, and can't exceed 62 linear inches (length + width + height combined). Checked bags aren't included by default, the Business bundle includes two, Elite Platinum includes one, and Elite Diamond includes two.
Frontier prices carry-ons and checked bags through its own Bag Price Checker, and the amount depends on your route, travel date and how far ahead you buy. Buying online at booking is consistently the cheapest point; the airport is the most expensive. We don't quote a flat number here because it changes by itinerary, tell us your trip and we'll confirm the current price.
A checked bag between 41 to 50 lb, or 51 to 99.99 lb, carries an extra overweight charge; one measuring 63 to 110 linear inches carries an oversize charge. Past 100 lb or past 110 linear inches, Frontier doesn't just charge more, it won't check the bag at all.
We never publish Frontier's bag prices because they're dynamic and change by route, date and how far ahead you buy, an agent confirms the current amount for your exact itinerary and can add bags to your booking before the price climbs.

Base fare vs. bundle, which actually costs less
Pick before you book, not at the gate.
Base fare, personal item only
Cheapest upfront
- Lowest sticker price if you truly pack into one under-seat bag
- No carry-on included, add one and the "cheap" fare can cost more than a bundle
- Bag prices rise every day you wait to buy one
Bundle or Elite Gold+
Better if you're checking or carrying on
- Carry-on already included, no add-on to remember
- Business bundle adds two checked bags on top
- One price at booking instead of a rising à la carte charge
Add bags before you get to the airport, every single time. Frontier runs bag prices through its own Bag Price Checker, and they climb as departure gets closer, peaking at the counter and gate. Prepaying online, or letting us add bags to your booking early, is the simplest way to keep a low base fare actually low.
