American Hotel Bonus of up to 10,000 Points
American just rolled out a promo encouraging people to bank their hotel stays to AA.
Link, register for MULT0 and MULT1 promos.
"Between September 1, 2010, and November 15, 2010, you can earn 3,000 bonus miles after 3 stays at any hotel participating in the AAdvantage program. Plus, earn an additional 1,000 bonus miles for every subsequent hotel stay, up to 10,000 bonus miles."
This promotion is also stackable with other current promotions, like the 3,000 AA miles per stay with Hyatt that I wrote about recently (that one only lasts until October 15).
AA miles are fantastic- they have pretty good availability, off-peak (40k coach to Europe) and one-way awards- even on partners. The only real negative aspect of AAdvantage is that you can't use them on US-UK British Airways flights, which is a bummer.
