Hello all FT'ers:

I currently have general member status with DL, UA, and AA (no miles with AA yet). I'm still in college, so the only flying I do is mostly to go home to Florida. However, I've accepted a job for next September up in Washington, D.C. and I'm interested to get your opinion on the best frequent flyer program out of there. I know that UA has a hub at IAD, and I expect to fly all around the country quite a bit with no one specific region. I understand that DL offers complimentary upgrades once you hit elite status, regardless if you purchased a full-fare B/Y ticket. That seems like a big bonus to me, especially since you have to have full fare on UA to get a comp. upgrade.

What's your opinion? Thank you much!
