One thing you might want to consider is moving. I am from a great city in the Southwest that everyone seems to be moving to, but I wouldn't work for a bad airline just to live there. Airline jobs are different from other jobs, as you can commute and you might have to live in your base. I have moved six times in seven years for this career, and I wouldn't have it any other way. I know, I know, my girlfriend/family/mother/favorite restaurant and all of my friends live here, and I don't want to move. Who knows, you might even like a new place better. Also, I can't count the amount of times friends of mine have made bad career moves for a woman, only to have the gal leave when he got based in her town. Honestly, if she can't move with you or wait for you to be senior enough to commute, she probably won't like the pilot's wife lifestyle anyway. I would consider another career if you just can't be without her. Just my opinion, take it as you will.
Good luck.
