How does Frontier's carry-on limit compare?
By volume, Frontier's box is larger than 23 and smaller than 2 of the 27 carry-on limits on this site. Within a centimetre on every side, it is the same box as Southwest. Spirit and easyJet publish the most generous limits. The tightest published limits are Icelandair, Ryanair and Breeze, so a bag bought for Frontier can fail there.

Frequently asked questions
What are the Frontier carry-on dimensions in centimetres?
Frontier Airlines publishes 24 x 16 x 10 in, which is 61 x 40.6 x 25.4 cm (converted). Compare in the unit Frontier publishes and keep the decimals: rounding a converted limit up is how a bag that fits on paper fails the sizer.
How strict is Frontier about carry-on size?
Frontier does not publish an enforcement policy, and gate checks vary by airport and by how full the flight is, so treat 24 x 16 x 10 in as the rule rather than a guideline: a bag that goes into the sizer with wheels and handles has nothing to argue about. 14 of the 15 popular carry-ons checked on this page meet it when measured with wheels.
What is the Frontier personal item size limit?
Frontier Airlines limits the under-seat personal item to 18 x 14 x 8 in and 35 lb (15.9 kg). It is a separate allowance from the carry-on; the Frontier personal item page on this site lists the bags that meet it.
What is the Frontier carry-on size limit?
Frontier Airlines’s own baggage page gives the carry-on limit as 24 x 16 x 10 in. Including handles, wheels and straps. A paid add-on, cheapest when bought with the booking. Measure the bag with wheels and handles, standing up, and compare the longest side with the longest limit.
Does Frontier weigh carry-on bags?
Frontier Airlines states a carry-on weight limit of 35 lb (15.9 kg). A packed hardside carry-on often weighs 15 to 25 lb, so check your packed weight with a luggage scale before leaving home if you are close to the limit.
Will a 22 x 14 x 9 inch bag fit Frontier?
Yes. A bag measuring exactly 22 x 14 x 9 inches with wheels meets Frontier’s published carry-on limit, with 1 in to spare on its tightest side. Bags whose listed size excludes wheels are often an inch or two longer in reality, so check the wheels-included figure.
Is the Frontier carry-on included in the fare?
On the page read for this site, the carry-on is a paid add-on on the cheapest fare. The personal item is the free allowance, so a bag that fits under the seat avoids the fee entirely.
