Delta just did the same to me - also by about +2 hours on the return. In order to book a different flight, it will cost $150 PER TICKET!!! So, I guess I am stuck with the new flight... But at least they emailed me about the change. I used miles to purchase the tickets -- and since the flights are free, I guess I can't complain
I travel a lot (and I mean a LOT) for work, and this is the first time that I have had an airline actually change a reserved flight on me. Of course, I have been through normal delays, etc...
Kristi, you (or your brother) are able to check your flight anytime either online or by calling the airlines reservations phone number. You will just need your confirmation or ticket number.
