From tomorrow until Sep 30th, you can earn up to 40000 miles by doing up to 28 partner activities. The detail of promotion is here
This promotion is harder than the one Delta had earlier this year, since I don't like US airways miles, I will only do 4 partner activities to top off 4000 bonus miles.
I will do Ereward transfer, Dining, Mall and live search club or Officemax purchase.
you can also do:emiles, lifelock, supershuttle, Thanks again(drying cleaner).
Other than those, if you really want to hit 12 partners, you can choose USA today, netflix,Buy miles, AIG, FTD.com, Energy Plus. Some of them are for selected States only.
Getting acitivities from Hotels or Car rental are harder since they require 2 times for same partner and count as 1 activity.Hotel points transfer has min 3000 requirements too, so I can not transfer just 1 miles to US airywas like I did with Delta. Also, points.com swap doesn't count either.
Overall, not a Great promotion, but does give something to top off account.
