I happened to call this morning for some of the rebooking needed because of the schedule change. Two things I noticed and asked.
1. Although many of my reservations are in R right now, because of my new flights are all after 3/31, the rep said they will be converted to something else, but don't know which letter as of now. And the new chart on the website not showing R fare class earning at all.
2. All of my newly rebooked flights in R, won't show waitlisted for premium/first class. The rep said all they can do is put a GO instead of STOP in the system, but there are many backend IT stuff going on which can't show me I'm actually waitlisted or now.
