As much as I would love to, I will be locating fairly far East on Long Island, and EWR will just never be a good option unless I am flying Int'l or to smaller EC markets where DL or someone else doesn't fly. My flying will mostly be JFK/LGA to IAD/DCA it seems, and occasionally JFK-SEA. (I work for Microsoft, so regular trips to HQ.)

If I am going to be in DL metal so much, it makes more sense to have status with them than with CO, even though I really would rather stick with CO.
