Yes, yes, we get it. The A and K seats are amazing, especially on the upper deck. Well done! 1 in 4 seats.
Now try being a Gold, paying full fare for a last minute ticket (i.e. the most profitable ticket that BA could possibly sell), and finding an A or K seat on the Friday night flight back from JFK, Sunday night from LHR to JNB/DXB, etc
Basically, it's lovely if you can book early and nab one of the good seats, and I don't mind it for leisure travel where I can book it well in advance
But for last minute business, I can't guarantee a good night's sleep if I'm stuck next to a snoring stranger in an E or F (why isn't there a divider like on Every Other Airline), or if people are padding up and down next to an aisle seat, but maybe you lot don't mind that?
