Hello! I had to fly LHR-SAN a few weeks ago for a family emergency, and I've been asked to submit a copy of my boarding pass for some administrative purposes at work.

Only thing is that I can't find my boarding pass anymore (I forget if I used a mobile pass or printed one out).

Has anyone gotten AA to email/send a past copy of a pass? AAdvantage Customer Service wasn't aware of any such process...

Thanks for your help!
