I flew Virgin Atlantic Upper Class SFO to LHR (VS 42) a few days ago. I've flown it a few times before, but this time after I boarded I noticed that the check-in agent had written a large "Z" (in quotes) on the boarding pass itself.
I recogize that this probably represents the fare basis of my ticket: Z is the most discounted business class fare code. But does anyone know why they would notate it on the boarding pass itself?
