If you're traveling light and dot your i's its a great option. My red flag went up at the bargain price so I researched the carry on prices. My free option went from the normal small suitcase to the 16"x14"x12" max backpack although they didn't bother to check it. I always forget to assign my seat so that's a wash. Print your ticket ahead of time to save $10. Plane & seats looked a little more warn but I would definitely use them again!
