One of the big airlines I hear a lot of hatred for regarding missing hidden fees is the ULCCs such as Frontier, Spirit, and Allegiant. Bags, snacks, seats with your party, etc. are not included at all in the base fare. The cost you see on those websites are for _a_ seat on that flight and nothing else. Many people, especially if they aren't frequent flyers don't realize that, and find out that the $100/person fare comes out to more like $200/person if they're flying with their family and needs seats together and at least a bag or two. If you know what you're doing, sure, it's transparent. But the people who fly most often on those carriers are people who never have or rarely do fly.
