Frequently asked questions
What size is a Frontier personal item?
Frontier Airlines gives the personal item maximum as 18 x 14 x 8 in and 35 lb (15.9 kg) on its own baggage page. One included with all fares, including handles, wheels and straps. Up to 35 lb. Measure the bag packed, because a soft backpack that fits empty can bulge past the depth limit once it is full.
Can a backpack be a personal item on Frontier?
Yes, as long as it measures within 18 x 14 x 8 in when packed and fits under the seat in front of you. Look for listings that state an 18 x 14 x 8 inch or smaller size. Straps and bottle pockets count toward the size if they stick out.
What is the difference between a personal item and a carry-on on Frontier?
The carry-on goes in the overhead bin and is limited to 24 x 16 x 10 in; the personal item goes under the seat and is limited to 18 x 14 x 8 in. On Frontier’s cheapest fare only the personal item is free, which is why its size matters so much here.
Researched, not professional advice. Limits change and can vary by route and fare; the airline's own page is the final word.
