I just wanted to let you know about my recent expernence with US Air, not Delta, but a similiar problem. I have had tickets for our Nov cruise since June. Today, I called US Air to ask a question on if I could redeem a voucher over the phone, I can't, and I also checked on my seat assignments. I had had a schedule change and when I was told about it, was told my seats didn't change. Well, the agent told me that they had changed and we were now all over the plane. I'm traveling with a 4 and 1 year old, not a good thing!! Well, she immediately put me on hold, about 5 minutes and came back with us having seats together in row 6. Usually the front rows are held back for frequent flyers, but somehow I got them. I'd call Delta and have them price out the flights over the phone. If it's the same price, buy it, if not, then ask them your question about the seat assignments, you'll get your best answer there!!
