Ok fellow FF's, I recently received a promotion at work and will be flying more often. I will be flying a lot from LAX or SNA to Charleston, WV (CRW). My boss says to fly either US Air into Pittsburgh or Delta into either Cincinnati or Atlanta.

I am currently Silver Elite with CO and would like to be able to use one of their partners for the miles. I was told that NW will get me to DTW but then I have a prop to CRW.

Can you give me your opinions on which might be a better choice for me before I purchase my tickets?

Thanks for your help,
Dave
