Sorry guys but I have the best medical excuse for wanting an upgrade EVER!
Boarding one of our longhauls out and see a message in system, "pax not well, request upgrade." Just about to call pax forward and security staff come and let us know she is wanting to speak to a supervisor. Supe checks the note in the booking and goes and speaks to the lady in question. Supe is soon back waring the biggest grin and trying not to laugh.
Pax needed an upgrade because she had period pains!
