Fair enough explanation. I'm travelling on a package deal (S-class) so I should be thankful to get miles at all, but I have a lot of CO miles right now and was hoping to beef up AA and at least get partial EQM. Maybe next trip. Sacrificing 10K miles due to the half-credit just to get half-credit EQM doesn't seem worth it to me. Thanks for your help though. I had been hoping I was misreading something somewhere . . .
