They told me this morning that they were having alot af flight changes that would be affective Sept. 1st.
I called Delta again after my parents came home and I could get their reservation number. They checked their flights and told me that they had not changed yet. I told them I was concerned because we have two reservations and wanted to be sure we would all be on the same plane coming home. (my parents are joining us a few days later, but we're all coming home together, and we bought my parents tix before we bought ours) When I explained our situation, she was really nice and said she would see about it for us. Come to find out, they had switched ours since I had talked to them this morning. So she said they would go ahead and get all of ours switched and assign our seats. It took a while but now we are together and the flight times only changed by five minutes each way.
Now I still have to worry about my mother being clausterphobic, isn't this plane is alot smaller?
Are our chances of being bumped worse now, because of them over-booking?

This vacation is a gift to my parents and they only wanted to go for 4 nights, but now if they are bumped from their 7:00 am flight, they could lose a whole day. I understand we could've been bumped before, but the lady I talked to this morning said she didn't know what they are planning on doing, going from a 107 passenger plane to a 50 passenger plane on three flight schedules for that day. And they're still selling tickets!! Are they doing such a thing as selling new tickets for the DL Connection flight without reassigning everyone that already had tickets on DL Express? I am sorry for rambling. I really don't understand all this. Like I said in my earlier post this is our second time flying so I hope I am not sounding totally ignorant about it all.
Any advice from someone who knows?
Thanks!
