Southwest is experimenting with new ways to speed up boarding — starting with upbeat music and flashing lights to get passengers moving

• Southwest is testing several new ways to get passengers moving and onto their planes. 
• The airline is using Hartsfield-Jackson Atlanta International Airport as an "innovation zone," according to the Wall Street Journal. 
• Among the new ideas are kiosks, special staging areas, and flashing lights at the start of boarding. 

Long boarding times frustrate passengers and the flight attendants who usher them through the loading bridge and to their seats. But Southwest Airlines is on a mission to change that.
