An update on the situation where upgraded flights are not credited automatically to the M&B account:
I just did the online retro claim for an upgraded flight and as always, the system refused it. So I called the Gold line and was told that there is a new procedure in place for the "next several months" where all upgraded flights will only post after 10 days in the M&B account. if they don't show up after 10 days, you need to do the online retro claim.
