Two questions:
1. Is this the right forum to post my FF question?

2. Which FF program should I use?
I just joined a consulting firm, and I expect to be traveling frequently for business, leaving from BOS. I get to choose which airline to fly, and cost isn't a big factor in my choice. My question is, which airline should I look to build FF miles on? I want to be able to spend them on a week vacation to Hawaii, and I'll be flexible as to what week I go.
