Tip:

Do you have any frequent flier miles expiring for American Airlines, etc?
I had them expiring in December and I can't use them.

I signed up for Points.com for free and they added bonus miles to my just for signing up a/c and now I am good for another 18 months.
Points.com lets you use your miles to get Gift Certificates, etc for your miles instead of a free flight.

Just thought this might help someone out.
They also have other miles/points programs too.
