Don't know if you're flying with smaller children or not, but, keep in mind there is a restroom in the front and one in the back of all SWA planes. It seems when our kids and our grandson were little, we spent quite a bit of time walking the aisle to the restrooms! On the same note, with SW current boarding policy, medical preboards will go first, then A's, then family boarding, then B's and C's. If you are not traveling with children (and not meaning what I am about to say in a negative way.....I have kids and grandchildren....but sometimes want to travel without them) and really don't wish to be seated near a lot of families with smaller children, head toward the back of the plane. It's not a guarantee, but, most families will grab the first number of seats that work for them. This technique used to work even better when family boarding was before the A's, because an A boarder could get on and scope out where most of the smaller children were and make a decision where to sit. Above all, have a good trip.
