I'd like to ask a different version of the original post....

Presently employed by a 121 regional, however the lifestyle is wrecking my marriage and family. I am actively pursuing two different Part 91 positions, either will provide better QOL and income than my current employer.

Now, let's say I have the opportunity to leave the regional 121 world in the near future in order to take better care of my family. Down the road in several years when kids are older and life is a little more stable, if I apply to either DAL or SWA (either would be great), how difficult of a sell will that be to an interview board?

btw...TPIC not an issue in my case
