Southwest is not concerned with the prices of other airlines. They do not engage in pricing to meet competition, or pricing below competition. CEO Herb Kelleher stated, "We 're not competing with other airlines. We 're competing with ground transportation." This philosophy has led them to be very successful because they are priced below the competition, but don 't raise their prices when the competition does.
Cost controlling is very important in the airline industry. Southwest is very good at controlling their costs. They offer a no frills service for people who want to get to their destination for as little as possible, and are not concerned about the bells and whistles like in-flight movies. Southwest also realized that when their planes are on the ground, they aren 't making money. They decided to keep their planes in the air as much as possible and have worked hard to keep a low turnaround time. They manage to unload passengers and load new passengers for the next flight within twenty minutes, which is shorter than the industry average. Southwest also uses only one kind of plane, the Boeing 737, in order to reduce costs of parts
