Well as far as DFW being a base eventually, it depends on who you ask. It is not a terminating station like ATL,JFK, and LAX, so until it is.....prob not a base. However, once you make relief command after~1 year, then the company will start and end most of your trips in DFW, as you will deadhead, er PX to ANC for the pacific crossing. Good because you don't have to commute , or at least not much, bad because you tend to work more days. Give it a go, I like it here, everywhere has it's downside, but CX is A STABLE place to work, especially nowadays.
