Need Help:
I flew AA135 LHR-LAX back in March. I have applied multiple times to credit this flight onto AS. My boarding pass and itinerary both show my AS number. However, each time I submit it for credit it gets denied as "Wrong Flight Number". The only thing I can imagine is that I upgraded using an Alaska/AA upgrade to C from O. Even my codeshare segments on AA operated by BA get denied. I have gone ahead to contact AA to ask them to prove that I was on that flight. Maybe AS can credit it manually.
Any other suggestions?
