Southwest
Southwest Airlines is the biggest airline--by number of passengers--in the world. The Dallas-based low-cost carrier first began flying in 1971 and by 2006 was offering nearly 3,200 flights per day. Unlike most other airlines, booking a seat on Southwest doesn't guarantee you a specific seat on the airplane. Instead passengers board based on their boarding pass letter and can choose their seat once on board.
