hello and sorry for resurrecting an old thread.

I am trying to claim for some TPs and Avios for my boyfriend, for BA flights from before he joined the BAEC. I have tried the claim form online, but the ticket numbers are not recognised and I have been told to send boarding passes to the EC by mail.

The boarding passes I have are electronic, not paper - so what's the best way of sending them to BA? Print out screen shots?

Thanks in advance!
