Beware United Airlines' tricksy check-in kiosks or you'll pay hundreds more

Anyone using the electronic kiosks to check in for a United Airlines flight now must learn how to navigate three more added fee hurdles. That's because United has rigged its check-in procedure with a onslaught of three pitches to load up more extra costs.

If I had pressed the wrong buttons on a recent cross-county flight I took, I would have accidentally paid another $523.68. How did I know they were the wrong buttons? Simple: They were colored and placed to look like the correct buttons.
