shred, continental already charges it in the ticket so you won't pay when you leave traveling on that airline.
American does not pre charge and you will pay upon leaving.
Belize-N-Us, the convience of pre printing your boarding pass was not created just for people coming here to Belize...it's really no big deal and the 25 times I traveled in/out of Belize I've never waited in a "long line" at Continental. Some airlines don't even let you pre pring any boarding pass traveling international so I think it's great continental offers.
