I don't want to get into a fight with you
bealine. You are well respected by many, including me. However, that doesn't always make you completely right. For your information I am in the business and I fly BA (Citiexpress) regularly. I have never been told by the crew that I'm not sitting in my assigned seat. I grant you that in
rare cases identification may be possible by seat location. However, in most cases it will be most unlikely. Perhaps I have no family who care if I'm blubber or not. And, lastly, you still failed to address the point I make about the computer's crappy seat allocation logic on lighly loaded flights. Oh, and believe me because I know, many positioning flight crew do not occupy allocated seats on light flights. They spread out - which is just what I do.
