Sorry,
You asked, its your problem if you don't like the answers. I spend plenty of time sitting next to guys like many of the above posters. I listen to their stories, good and bad, I am not exaggerating when I describe the perils of reserve. Plenty of guys can corroborate the facts. Like me or not, doesn't matter. The reality is you sound like a very devoted family man, this job is extremely difficult for families to understand, the fact that you are asking these types of questions means that you don't fully comprehend what you are getting into.
Stretch your imagination a bit. You are junior, your bidding in the bottom 25%, put all your kids birthdays on the calendar, wife too and all your close family as well. See how many fall on weekends, you probably will be on reserve, many reserve lines are over weekends, and even if you aren't on reserve you are junior and probably flying over the weekends anyway. Some domiciles have movement, some up some down, can you predict which you will be in? How fast can you move your home? You can only transfer when they process them. I am sorry you don't like the answers, but a 25 year career allowed me to see many corners of the business. I have been at multiple airlines and consider myself a Journeyman in the business. I am the guy who comes to work, does my job the best I can, and haven't been in the CPs office, except to stop by and say hello. Bottom line, I don't bend metal, or get in trouble with the FAA, don't hassel F/As and have never scratched a plane in 25 years, in other words, I make them money and they don't have to do anything extra, that's why I am still there, unmolested.
