a follow-up to my question about how online upgrading works, it looks like something is wrong with the itinerary display page. i made upgrade requests that cleared for two of my flights (the ones in Z class, which are the upgrade buckets), and the page still shows economy with economy seating, but when i called the agent was able to give me first class seat assignments which also are not reflected when i pull up my reservation. (as an aside, i had them replace my FF# with my ConnectMiles number so i can try for a CPU on the PTY-SFO segment [no upgrade space is available now; can't waitlist, apparently], and it's not showing here either, although the agent confirmed it's in the reservation).
