I've only had 1 Op up transatlantic, EWR-LGW in 2003. I did not volunteer --didn't know they needed help or I would have jumped at the chance for op up or bump. Stayed late in the PC, was walking to gate C123 19 minutes prior to departure, when I heard my SO's name paged. Who did they page?? Me Plat, her zilch..... I was shocked. Happily shocked with 1A & 1B. The food was much better.
