And Easy Way to Pick up Some American Miles

American Airlines loyalty program, AAdvantage, recently joined the social media sphere with new pages on Twitter and Facebook. The airline decided to promote that latter with a "Mystery Miles" promotion - just "like" the AAdvantage page on Facebook, and you'll receive somewhere between 100 and 100,000 free miles. (Sadly, my free miles were on the low end of that.)

This is an incredibly easy way to get some free miles - so you might as well give it a shot. You can get all the details here.
