I have an award itinerary that I booked well before 3/3, to which changes were made (also well before 3/3), for departure months from now. Post-changeover, I see that the flight I wanted to keep, as well as the flights I changed away from are all listed on the "view reservation" page. However, the receipt only lists the correct current flights, though it shows the cumulative number of seats to be assigned.
I've mostly seen issues with segments vanishing, but has anyone else had mysterious segments appear? Is this something that will be fixed in the ongoing re-syncing process?
