Most of my BA usage is Club Europe out of LGW and I would agree with Martyn about the 1 in 4 or 5 flights being of the Hinge & Bracket style.
What spoils it for me is the removal of the simple touches like the hot towel and more recently the chocolate off the tray. I complained about the removal of the chocolate what I got in reply was a load of clap trap that insults ones intelligence. Bland statements that say “our customers tell us” and BA is “committed to providing a good service”.
During the hard times they should have looked for savings in other areas rather than taking it from the passenger. But there are staff out there that do still go the extra mile, its not all bad!
