This has happened to me the last few times I've tried to check in. I start from the home page under "Print Boarding Pass". I use my OP number, and it returns the message "! We could not process your request. Please see the message below and make revisions." Below that it indicates that you could try Confirmation Number, eTicket Number, or OnePass Number. Above the OnePass number box is the message "! Multiple eTickets were found for the OnePass number entered. Please enter a Confirmation Number or an eTicket Number." I certainly have multiple eTickets booked/pending, but only one of them is within 24 hours. Why can't it understand which one I'm trying to check in for?

Has anyone else had this problem?
