A bargain airline in the United States. Known for the bare essentials on their flights and they must be doing something right because they are the most profitable airline and have never had to file for bankruptcy. Part of the reason is because Southwest bought and stocked up on fuel reserves back in the 1980's when Jet fuel was a lot cheaper. They are also know NOT to charge you a ton of hidden fees. An example: allowing your first two checked bags to be free. There is also no first class or coach sections and there is NO assigned seating just boarding groups A, B, and C. Many US based companies prefer to send personal on domestic business trips VIA Southwest because of the amount of money they save, dis-spelling the "white trash" stereo type.
Self centered people cry about Southwest Airlines because they don't have TV's on their aircraft. I on the other hand am amazed that an airline can get me from Los Angels to West Palm Beach in roughly 5 hours without losing my luggage and at an amazing price. Thank you Southwest, YOU ROCK!
