I just called Delta and had them change my seat assignments for my return flight - the India rep also noted there were slight changes in the times from when I first booked in August. She re-issued me new online tickets when she changed my seat assignments, which have new ticket#'s, but same confirmation #. With the baggage changes since I booked in August - it appeared to me that I'd now have to pay for my first checked bag as the new etickets have a 1/1/09 issue date. I called Delta back and another rep told me that I would not have to pay the checked bag fee, but I'm worried as the new issue date is 1/1/09, and have new ticket numbers. Do I just bring copies of my originally issued tickets - with the old #'s/issue date to the airport and present them if they try to charge me for my first checked bag? Do I need to be worrying about this?
