Best Carry-On Bags for Frontier Airlines in 2026

Frontier Airlines Bag Policy

Frontier is a ultra-low-cost carrier, and like Spirit, most of their revenue comes from bag fees. Understanding their policy is essential before you pack:

• Personal item (free): Must fit under the seat. Maximum 14x18x8 inches.
• Carry-on (paid): Must fit overhead. Maximum 24x16x10 inches. Buy in advance online — gate prices are significantly higher.
• Checked bag (paid): 62 linear inches, 40 lbs max.

Frontier's personal item is slightly smaller than Spirit's, so double-check your bag dimensions before flying.

Best Personal Item for Frontier: Herschel Pop Quiz Backpack

The Herschel Pop Quiz Backpack (check price on Amazon) fits easily within Frontier's personal item dimensions. It has a padded laptop sleeve, front zipper pocket for quick-access items, and a clean, stylish design that works for both travel and everyday use. The 22L capacity is enough for a weekend trip when you pack smart with packing cubes.

Best Carry-On for Frontier: Travelpro Maxlite 5

If you're paying for a carry-on upgrade, the Travelpro Maxlite 5 20-inch carry-on (check price on Amazon) fits within Frontier's 24x16x10 inch carry-on limit and weighs just over 6 lbs. It's the choice of frequent flyers and flight attendants. The PowerScope handle is durable, the spinner wheels roll smoothly on any surface, and the exterior pocket lets you grab items without opening the main compartment.

Best Budget Carry-On for Frontier

The Coolife Luggage 20-inch Carry-On (check price on Amazon) is an affordable hardside option that fits Frontier's carry-on size requirements. It's made from lightweight ABS, has four spinner wheels, and a TSA lock. Great for travelers who fly Frontier occasionally and need a reliable but affordable carry-on.

Strategy: Maximize Your Free Personal Item

The smartest move on Frontier is to travel with only the free personal item. Use packing cubes to compress clothing, wear your bulkiest layers on the plane, and choose a personal item with good organization. For trips of 3-5 days, this is completely doable.

When to Buy Carry-On Allowance

If you need a carry-on, always purchase it during booking or at least before check-in closes. Gate prices on Frontier can be $100+ per bag each way. Buying it in advance during checkout saves $30-60 per bag.

Frontier vs. Spirit Bag Policies

Both airlines charge for carry-ons and allow one free personal item. Frontier's personal item limit (14x18x8) is slightly smaller than Spirit's (18x14x8). In practice, the size difference is minimal for most bags, but measure carefully before choosing your personal item bag.
