Yesterday my TA made a booking for a EDI-LHR-EDI flight. I was waitlisted for the 07:40 and confirmed on the 06:40. The waitlist did not clear so I decided to have a bit longer in bed (plus earn double tier points and double miles) and changed to the BD flight at 08:30. When I went in to "Current Travel Plans" I was surprised to see that in place of the BA flights were my BD flights! It must be tied in with the moved to Amadeus and the TA retaining the same ref.
