I have never flow Southwest before. With small children, I never liked the prospect of not having assigned seats. Now that my kids are a bit older I am contemplating giving Southwest a try and have a few questions. I know that Southwest has boarding zones and that your zone is determined in part by when you check in (up to 24 hours prior). I also understand that certain fare classes board before others. Aside from checking in early as possible, if I want to move my boarding zone up is the only way to do this to buy the business fare? If I purchase the "gotta get away" fare, do they offer a better zone for an additional fee?
TIA for any help.
