Back in the paper ticket days, we used to buy multiple back up tickets for the return trip prior to leaving the USA in case our original listing on Delta was full. We did this because we were told that you couldn't make these arrangements while in Europe. Is the case? How do you make new pass ride listings while in the airport if you find your flight is full. Can you relist using "travelnet" without bringing a laptop on your entire trip? Will the agents be helpful in relisting you to a different destination? Thank You for your reply Debbie
