The symbol of Southwest Airlines is a heart. This has been a theme of the airline’s since the beginning. They launched at Dallas Love field. Their flight attendants wore pink hot pants (designed by founding airline President Lamar Muse’s first wife). Automated ticket machines were called “Quickies.” Peanuts at Southwest were once known as ‘Love Bites.’ Their New York Stock Exchange ticker symbol remains LUV.
On Sunday, though, it took on a whole new meaning because one of their planes had to turn around because a human heart was left on board.
