Ba 109/108
(I posted this on the BA forum, but didn't get anything, so I'm hoping it may be different here...)
In short, I'm doing LHR-DXB-LHR as part of my DONE4. I'm basically turning around back to LHR on the next flight. My TA couldn't confirm the return flight, but ITN shows D9. Any reasons why? Anything I should be worried about?
