How to measure linear inches

Measure the bag’s height, width and depth at the widest points, including wheels, handles and side pockets, then add them up. A 28 × 19 × 12 in suitcase is 59 linear inches and fits under the 62-inch limit. Most suitcases sold as 29–30 inches land right at 62 inches, so check the exterior size on the spec sheet before you buy. Our suitcase size chart shows typical sizes.

Overweight and oversize fees

  • Overweight: 41–50 lb: $75. 51–99 lb: $129. Over 100 lb not accepted. Per bag, each way.
  • Oversize: 63–110 linear in: $75. Over 110 in not accepted.

Fees for overweight and oversize bags are charged on top of the regular bag fee, and a bag that is both is often charged both.

Ways to avoid the fee

  • The free personal item is 18 × 14 × 8 in, the same size Spirit used, and is size-checked at boarding.
  • Elite Gold and higher get a free carry-on; Platinum and Diamond also get checked bags.
  • Travel with only a carry-on and personal item. Frontier Personal Item & Carry-On Size.
