Hello all,

I am relocating to the NYC area and for many reasons (proximity & company policy) EWR will become my new home airport and and most likely UA/CO my preferred carrier. I am a barely legal DM, i.e. I fly about 150K/year. Mileage most likely will not change much, so it is obviously not enough to spread this over more than one alliance. The company has a *A TATL contract carrier, so UA/CO seem like the best bet as flying will be 50/50 domestic/intl. I am all geared up to do the UA 1K challenge (btw 35k in 90 days = 140K in 1 year). I rather do the UA 1K challenge and have CO Platinums on CO metal ahead of me until the end of the year instead of ending up in the second highest tier next year. Anyone else here recently jumped ship and has the DL convert perspective? What's better, what's worse?
Thanks.
