I was trying to do this segment in F. itn.net showed a lot of availability, and while making the reservation airline (BA) accepted fine. Within an hour when ticketing was attempted, segment came out waitlisted. I skipped the routing via DXB and tried something else.

Does this happen a lot? Are there lots of BA Gold EC members that wait for upgrades in the last minute? I tried ticketing within a 24 hr window from an Area that allows this for OneWorld RTWs.
