I had a bunch of AAdvantage miles. Got all of them with my the 30K-50K bonus when getting an AA Citicard, charging the required amount, then cancelling card. Within a month or two, get an email to open another credit card account. Did it 4 times. UA/Chase had it but finally realized there are a lot of us doing it, so now a 24-month gap required. Anyway, tried to book a November US-BKK RT on the AA website, but not possible. Called the AA reservations number and hooked up with a fantastic agent (in US!!). She put me on AA from my mid western US home to ORD, then Cathay through Hong Kong. RT for 75,000 miles. Got on Cathay site and upgraded to economy-plus giving me legroom on all 4 segments for $260 I then received a 7500 mile rebate from AA-Citicard, so complete trip 67,500 miles and $260!!! Still have enough miles for another one and in the process of cancelling the current card.
