Hey all,

Sorry to revive an old thread, but with the 380 continuing to fly to BKK, the use of qcredits have become a bit more relevant to me. So I was able to upgrade one segment already from J to F (after quite the toil) but currently no availability exists on the other 380 segment I have booked even though every F seat is empty according to EF. So if on the day of travel, there are empty seats, how easy would it be to use qcredits to upgrade day of, either at my original check in location or even at DOH right before the flight? Has anybody recently pulled off a scenario like this? Thanks!
