As I settled into my tiny seat on a recent flight, a woman asked me if I’d trade my aisle seat for her middle so she could be, as she said, ” with my girls.” … After all, it was just a short 90 minute flight and for the sake of a beleaguered mom, I could afford to be chivalrous. … My wife and I have traveled all over the world with our kids, and many times, have relied on the courtesy of strangers to untangle the twisted airlines’ seating plans.
