FWIW, if you check into Y and subsequently get an easy update upgrade confirmed message, do the following:
- Go back online.
- Cancel check-in.
- Check-in again-- into F.
(Ignore the scary warning message when you cancel your check-in.)
Or just go ask any CSR to offload you and check you in again. Also, in this situation, if the CSR says you haven't cleared, ask them to check the PNR to see if you are confirmed in NF, because they just check the DM by default.
