I have a flight tomorrow from PEK-IAD-ATL on UA. I called today to ask about biz class availability. They told me there are 7 seats left and if i applied an SWU (which i don't have) then i'd most likely get the upgrade. Since i don't have the SWU (i'm premiere exec, not 1K), has anyone had experience with getting upgraded automatically at the gate? Does that still happen on UA flights? Any tricks to getting the bump to biz class? PS: While i was on the phone with UA today they upgraded my friend who's traveling with me who has no status to Economy Plus for free so he could sit next to me. Great customer service!!
