If you accept a conditional job offer and in the mean time a better opportunity becomes available that would not require a commute. Are you set in stone or is it feasible to contact the company and let them know you decided against the CJO?

Hell, some people just go "AWOL" from the CJO.

There is literally no commitment for a CJO, especially among a regional. If a better option becomes available, take it. Remember, the Airlines will furlough you without any notion of decorum, respect for your "feelings" on the matter or considering your personal situation.

Do whats best for you and yours. A corporation has no feelings. Write a respectful "thanks but no thanks" and dont look back.

I'd emphasize the last part. Don't burn bridges as you may need to cross that river again if something goes sour.

Do what's best for you and politely tell the company you have found greener grass, you're not the first person to do it, they get it, especially if it will help your family. Don't burn bridges and I've them the middle finger after you found something better. Just be professional

I am by no means an expert, but I would think if you accept a CJO and then later turn down the class date at a company (or quit) which has a major airline as its owner, that would not look good later on if you applied to the parent company. Hence the question on the application..."have you ever interviewed at or been employed by any of the following carriers.....?"

I am thinking specifically of AA and DL and the regionals that they own outright. Somebody correct me if I am wrong.

You're way over thinking this one. Do what is best for you and your family, and let tomorrow worry about itself. If a parent company gets bent out of shape because you turned down a CJO for personal QOL reasons, and you were courteous and professional about it, then you probably wouldn't want to work for that parent company anyway.

Yes way overthinking. Like deciding to go to KFC after Taco Bell hired you.

Good analogy, since both are owned by PepsiCo.

Yum!
Since 1997.
Not pepsi.

Haven't been in either one since 1995.
