Hi.

I've been traveling pretty regularly for a while, but I've just started a new job where I'll be flying out and back every week. But I don't know where. I may fly to Detroit for 3 months, then to L.A. for 2 weeks, then to Dallas for a month, etc.

With BWI as my home airport, which FF program would be best for me? BWI's biggest airline is Southwest, but I don't want to make Southwest my airline. I want the perks (upgrades, lounges, first class, etc) that come with status from a standard airline.

So it seems to me that either Delta or United would be the way to go. But I don't really know which one to choose. Is one better than the other, can you earn status faster with one than the other? Does one have more/better flights to/from BWI?

Any experienced BWI based road-warriors out there that can point me in the right direction?
