We were upgraded from tourist to biz on BA returning from London, but the plane was oversold.
What I can't get over is seeing and hearing an FA take someone they know or who knows somebody in their family or something from tourist to biz or first after the plane takes off. I understand it. After all, it's the kind of thing we experience in this world all the time. My problem is I don't know anybody to get that kind of gift when I'm flying!
And yet I've heard stories about a husband and wife separated due to different tickets and one is in biz or first while the other is back with the great unwashed. The FAs wouldn't let them visit or sit together even for a few minutes! How rediculous!
