Before you travel through the sky in the belly of a silver tube at hundreds of miles per hour, wouldn’t it be nice to know which extra fees you might be charged for doing so? Kayak has a great chart for doing just that.
You can filter results by specific airline. Note that it’s for US route tickets and may not include every single possible fee you might be charged – those airlines are rather clever after all – but it should cover you for most of them and be reasonably up-to-date.
