30 years and no domicile concerns? I’d go to AA.

The only caveat for me would be what is AA’s flying and seniority like where you want to live (DFW)? You might be able to upgrade in 5 years, but if it means commuting to LGA to sit reserve for another 5 years until you can hold DFW it doesn’t really matter. How’s the WB flying out of DFW? I have no idea, but if you have to commute for it, it may not be worth it to you.

I had the choice between United and SWA living in Denver. Denver was United’s senior base and no WB flying at the time. I was looking at a several year commute just to get into base, an upgrade as long as SWA in base, and NB flying only in base. That being said, I only had a 15 to 20 year career - 30 years? I probably would have gone to United...
