If you end up with F9 then I'd suggest you not commute.
I've been married for 22 (some good...some bad) years and have a wife and a 15 year old son who has known nothing but dad living out of a suitcase, getting cranky the day before a commute (because of the high loads/weather), being tired and cranky on the first day home, and missing most family get togethers.
Yes the money is good in the left seat of a 757/767, but knowing now what I know I would never have commuted in the first place (which I have done for 20 years). Now my son is on a dark path of alcohol and drugs, and I feel at lot responsibility is at my feet as I haven't been there for my son.
As a result we've put up everything we own for sale at a loss and we are moving to where I can drive to my base, that way after my son returns from the wilderness camp for troubled teens we can start fresh and hopefully be able to restore my son to a better path as we only have 3 short years with him, before he leaves.
I've wanted to be an airline pilot since I was three years old, it's a very satisfying experience to be here, but comes at a potentially very expensive price. Nowdays airlines treat their pilots with less and less dignity, and you will be just a number in a sea of pilot uniforms. So my advice is do what you think is right for you but not at the expense of family. Good luck to you !!
