My first real flight with BA was a trident flying to Alicante on 18th April 1974, just 18 days after they officially formed as British Airways.
If BEA counts in the BA count, then my first flight was to Edinburgh on a vanguard. A full meal service all economy, I recall how rushed the crew were to serve and clear before the flight landed. I think I even have a photo of the meal somewhere in my massive collection of pics.
This past week at home applying for refunds I've been reminiscing about my past trips. I've been longing to go back to Scotland so we've booked a trip in August to Edinburgh and Aberdeen. It's in true FT style flying around the houses with lots of TP's. Just hoping we don't have to cancel.
