I was tipped off by the One Mile at a Time Blog;
1)
Free International Gateway Stopovers have been eliminated. Specifically, if you were ticketed before 4/8, you can add the intl stopover; if not you can't.
2)
AAdvantage AAnytime Awards are going up and will have more than one level of AAnytime is the discussion thread for that.
I verified both at the Exp desk and re: #1, changed LAX-HKG-HAN to TPA-LAX-HKG-HAN but couldn't change HKG-LAX to HAN-HKG-LAX-MIA (could do HKG-LAX-MIA though). Reason given was HAN would require reticketing.
I added LAX-MIA (now have HKG-LAX-MIA) and will try to add HAN to that later.
Surprised if this is the first post here on it.
