You learn something new every trip....only two bathrooms on the 737 and the front one hard to get into because no line is permitted and you have to time when you stand up...though in the third row (W)I finally had to make my way to the back. Also southwest does not even sell sandwiches, etc, even on long flights...only option was the free little bags of salty snacks....if I had known I could have purchased something in the airport. It was a long flight.....
