Welcome to the world of Mileage Accumulation.
My advice is to read all these boards carefully. You'll end up using a variety of ways to get the miles you need for FC to Europe.
What you'll want to watch out for is the next Kelloggs/Valuemags.com type promotion. I picked up lots of miles using both of these promotions for about $0.67/mile after the charitable tax deduction. The Valuemags promotion was much easier and took lots less time.
I, myself, look forward to picking up 300K more miles in the next few months so I can hit the 2MM mark on AA.
My local charities are also anxious for the next promotion.
Have fun!
