So I email them:
... I haven't yet received the miles, and miles are always deposited within 2 days. I even mailed in the ticket to the
mailing address you specify...
They reply, 8 days later:
To credit missing flight activity ... in your Dividend Miles account, we require both a copy of the ticket receipt and the original boarding passes to be submitted ...
Ok, at least pretend to read my email, please.
So I call. I have status on US Airways, so I call my spiffy elite line. I figured I'd get some perky, happy customer service rep - I mean, shouldn't frequent flyers get better service? Nope, the CSR was completely unenthusiastic and bored.
I used to be happy with US Airways: usually on time, usually pretty good service, usually just kind of another mainline carrier. In 3 events (miles not normally posting, lousy and slow email support, unenthusiastic customer support reps), in the span of a month, I've completely lost any enthusiasm to fly with them.
