I don't know about any upgrades. But Delta's is all hyped! I have an 11 grandson and a son that has been trying to get home on the Dec. 27. What is today???? the 30. They have done everything they can think of by not putting them on any fly at all. They have bumped them everyday and sometime twice a day. Why because other people have booked to fly, go figure. So where does that leave them in Iowa. O they got a plane that can go to Detroit (what a joke) to Atlanta and get home at 10 something to night. Go Delta! this will be the last time anyone of us will fly with them. They are a joke. My grandson hasn't even had a Christmas with his mom or us thanks to them. I will drive the next time and forget about flying. They say they understand, well if they really understood anything then they wouldn't bump anyone to get them on the next plane. So far they have been bump at least 10x. We could of road up there and got them and had them home before they even took of today. O' there still not on a plane yet. I wonder if they'll get a upgrade on anything. I mean this must be a very special plane there on. If anyone see this say a pray. If they are not delivered on time and safely there will be great pain for Delta. I am be on mad and I can't say what I really want to say. O' One of the ladies even hung up on my very sweet husband that never get's mad. I'm with my son Delta S---s. He said a few other words too but I won't say them. I wouldn't even send my dog with Delta. Des Moines Iowa does not know their b from a h in the ground. And that is nicely put. Don't let them get a hold of your grand-kids. You will never know where they'll be. Thank you I had to get this off my chest. I don't know if I'm in the right place or not. If not tell me and I'll try to put it in the right place. Maybe after I calm down. VJ
