I was surprised to see that I could "boost" my miles to keep my Silver Status through 2015 for $499. I needed 9000 miles to reach 25k, so this was far easier (and cheaper) than a last minute mileage run.

Plus, after the merger, I will have the equivalent AA status.

I wish I could do the same on United where I need 6000 miles to keep Gold but it would cost $1600 for those miles with PQM Accelerator purchase.
