I had approximately 10,000 miles towards my next group of 4 and received 3 upgrades after emailing in (now sitting on 30). AA Customer Service called my home line yesterday while I was at work (didn't leave a message) and then sent an email asking me to call in to discuss. But when I brought up my account on-line this morning in anticipation of calling in, I saw that they had deposited three upgrades dated yesterday. So no reason to call in now and I was pleased with the result.
