Has anyone else had problems with the airtran online check in not working? I get to the point where i have to put in credit card info to pay for my extra bag, and I get an error everytime when I try to pay. I've tried mine and my friends card, as well on different computers at different houses. I get this message after my first attempt: Unable to pay for your excess bags. Please try another credit card or Click "Cancel". Then trying again, i get: There was a problem processing your request. We are unable to complete your check-in at this time. Please proceed to the airport for check-in. Anyone else have this problem??? I only care because it's only $10 if you check your bag online, but $20 if you do it at the airport. I hope they will only charge me $10 at the airport, since this is an error on their part.
