I would say this is more buyer ignorance then beware of Spirit Airlines. Spirit has pretty clear information on what is allowable size and not and what their costs are for carry-ons and check-in bags.
I agree. I've flown Spirit, Delta, and American all three this year. I saw people getting on both Delta and American with huge bags. No way were they legal carry on size. I saw several people on those flights have to check their carryons (for free
) because they couldn't squeeze them in the overhead bins. I also saw alot of other people whose bags were obviously oversize, but they were able to squeeze them into the overheads, so got by with it. On the other hand on both my Spirit flights, I saw a person who had to pay to check their bag, due to Spirit measuring them. Their bags actually looked smaller than the bags that American and Delta was letting people on with. Even though the bags were technically oversized, American and Delta would have let them get by with it, because they are so liberal with what they let people carry on.
I have a Vera Bradley rolling duffel (this one but in theBlue Rhapsody print:
http://www.verabradley.com/product/...77924/c/638/sc/772/p/1001811.uts?fromSearch=1). If you look at it, (22"x12 1/2"x11"), the height is just a tad too tall for a legal carry on. However, I have squeezed it into the overheads on both American and Delta (I know their limits for carry ons are supposed to be 22"x14"x9", but also know I've never had a problem getting that Vera rolling duffel wheels first into a Delta or American bin, as long as the top is not overpacked). I didn't even think about taking it, because I knew that unless it was really obvious oversize they wouldn't say a word about it (and for that matter even if was really oversize, they'd still let it pass as long as I could squeeze it in the over bins.) It was a tight fit on top, but did go. Knowing how Spirit is with their bag fees, there is no way I would even attempt to take that bag on a Spirit flight.
