Southwest launched their service for the 737-800 aircraft in April of 2012 with their new Evolve Interior. The Southwest Evolve Interior is an eco-friendly design that is part of the airline's commitment to be a "green" company. This aircraft with a 175 seat capacity features new seats with a more comfortable bottom cushion that allows for better lumbar support and a fixed winged headrest for each seat. The new seats are also made with E-leather, a lightweight and more environmentally friendly alternative to traditional leather.
Although there have been concerns about passenger comfort with Southwest's new Evolve interior on their 737-700 Evolve seat, this does not seem to be an issue on this 737-800 aircraft. The 738 offers overall more legroom, leaving passengers with a 32" seat pitch. In comparison to the 737-700, the 737-800 also features the new Sky Interior with a sculpted ceiling and sloping overhead storage bins which leave the cabin with a much more open and spacious feel.
There is no pre-assigned seating for Southwest flights. Your time of check-in will determine whether you are in Zone A, B, or C for boarding. The earlier you board, the better chance you'll have at the seat you want. There is no audio or video entertainment on Southwest flights.
