I have had the opportunity to use MyIDTravel several times, and I love it. I do not need to worry about loosing paper tickets and I can make last minute changes instantly. I know refunds on DL are instant on unused coupons, manual for partial segments once the journey has started. Many airlines offer the instant refund however a few still process refunds manually. On an unrelated note I want to send out a KUDOS to DL and UA. I just nonrev'd on both and must say that everyone who helped me or talked to me during my trip were fantastic.
