We are a family of 4 -- me, DH, DD7 and DD9. We have the opportunity to go on a "last minute for us" trip the week of 11/8. We are frequest Southwest fliers, but for this trip would be using American, so I need some help. The view seat diagram for one of our possible flights shows only single seats left on the plane. Is there a chance we would be able to sit 2 and 2 when we actually get to the airport? Is there something I can do when booking to help facilitate this? If not, I am strongly considering coming home a day early where there are lots of seats available. Any advice? Thanks in advance for the help.
