I have been trying to get miles posted for a flight I took in early April. I faxed and mailed the original boarding passes. THe csr told me I needed to "resend" the original boarding passes again (hard to do when I've sent the originals). So I asked for a "supervisor" -- he was rude and told me the only way I'll get the miles is if I send the original BP's "again." Neither one of them seemed to be able to grasp the concept that I'd already mailed the originals so I cant mail them AGAIN.
I had the same scenario with NW, but they posted the miles immediately.
