Tough room but all good points. No crystal ball so do what's best for you and your family. I had a chance to fly the 757 for TransMeridian. Would've been a great choice for me to fly the plane I always wanted to fly and I'd be able to commute on Tmid from my home city. Decided to stay at my regional to get more PIC time and in the meantime, Tmid closed its doors. I know SWA and DAL aren't going anywhere soon so ask yourself how both choices will affect your family. Good luck to you!
