I largely agree with what has previously been said. I flew it for over six years and only recently moved over to the Bus. My biggest additional opinion, since you are clearly concerned about impact on family versus what’s the most fun for you, is that there really won’t be a lot of variation from your family’s perspective between the various domestic fleets. Your schedule will consist of some 5-7 day trips, some random morning or afternoon turns, and 2-4 day trips as a junior bidder. The toughest thing about being towards the bottom of the list is the inability to be in control of your awarded schedule. That said, if you are aggressive on the Trip Board you can shuffle your schedule around and increase the number of important dates you get off and minimize commutes.

As another poster noted, there is a vast difference between the domestic flying and 74 flying. That is mostly long haul international.
