On the flight coming down (Delta), when I got there they said they'd changed my seat & asked if I minded being changed to the window seat (heck no, love it), so when I got there a young couple were in the other seats, so obviously they switched seats around so the couple could sit together I bet they'll do that for ya'll also, especially if you leave word that you are trying to get seats together.

Last trip, my daughter & I traveled together & unfortunatley we did not sit together but were within sight, and hey it was all good, we made it there

Bottom line, always a lot of single travelers on the plane won't mind switching around a little bit so ya'll can sit together, I bet....
