I am on the upgrade standby list for a flight tomorrow. I paid dollars and miles, but I don’t have any status. Unfortunately, I can’t check in online, not we’re they able to help me over the phone, this I cannot see where I am on the upgrade list. As of this morning it showed 6 available first class seats on the seat map, now it shows none. What I don’t understand is what it means that the 2 people at the top of the list have a blue check mark and a seat number, but the people below them are numbered 1 through whatever. Is it still possible for someone with a higher priority to come in and bump those top two out, even though there are seat numbers assigned?
