Pro-Tip for Spirit Airlines Travelers

Spirit's weight limit for checked bags is 40 lbs, NOT the standard 50 lbs. Pack a portable luggage scale — going over by even 1 pound triggers a massive $75 overweight fee.

Best bag selection: Get a specialized under-seat personal item bag (18x14x8") like the Narwey Foldable Travel Duffel, which fits Spirit sizers exactly, allowing you to fly fee-free.

Exceeding either sizer dimensions or weight caps will result in extra charges at check-in or boarding gates.
