"The airline became famous early in its history for getting planes in and out of gates quickly — often referred to as the “10-minute turn” — reducing the time planes spent on the ground without passengers. Today, it takes about 49 minutes for Southwest to turn a plane around, which is still faster than the other major U.S. airlines, according to data Southwest shared with investors in September.
The airline has said it aimed to speed up its plane turnarounds by five minutes. Among other things, the company says, it will digitize more paperwork and use technology to more quickly move bags between connecting flights. Southwest is even experimenting with adding music that plays at 120 beats per minute to encourage customers to move faster as they board. These and other changes should free up flying capacity, according to Southwest."

Brilliant idea, rely on music? Maybe they should play the circus song or the opening to Benny Hill
