I can't complain if you got your money back in full. There are people in ORF that have had a problem with that since service to that airport is being ended.

Things go wrong with the airline schedule periodically. I had a US/UA combination that got screwed up by US and rebooked onto a much worse flight. I was on a US schedule that changed 3 times in 2 weeks and happened to be in a travel agent's office and ran into someone else flying the same routing. I warned them about the changes and they pulled up their flight to learn it had changed. Yes, things change and get screwed up, and the plans we've put into place get screwed up, but the more you fly the more you end up expecting it and make the adjustments when it happens.

Don't be the people on Airline.

No Flyi Problems For Me Plus Two
 

Three of us had reservations to fly from IAD to Orlando. We showed up early and they asked if we would like to take an earlier flight. Of course we said yes because who wants to wait in the airport when you can get on a plane?
After a week's cruise we arrived at Orlando airport, checked in and we were again asked if we wanted to take an earlier plane. HECK YES.
It was time to go home. Everyone was extremely nice and we had no problems whatsoever except that the money we saved allowed us to shop more. :D

CS Probably Good Except The Off Shore Call Center?
 

I have called and gotten the off shore call center, and have had to be transferred back to the IAD one.

I don't like the idea of the off shore call center.

Maybe DH hadn't called you before you caught the change because they were waiting to see what th options were going to be to re-accommodate you.

The carrier I work for (HP) will call on a schedule change (that's what this is) no more than 45 days out. I agree with everyone else, this is not that big of a deal...FlyI will (should?) either rebook you on another DH flight or refund your money. They should not put you on another carrier on a schedule change!
