Southwest Airlines announces its new Boeing 737 aircraft are due to fly in 2016. The tremendous improvement in seating will allow passengers to enjoy the enormous comfort of not quite an inch more space than on older aircraft..

So, on a future SW flight, be happy when all settled into your seat and a 300-pound passenger plops down next to you. If you’re really lucky with all the extra seat space, you may get a furtive glance at your elbow rest just before it becomes totally covered by excess blubber.
