Song, LLC was a low-cost airline brand owned and operated by Delta Air Lines. Song's main focus was on leisure traffic between the northeastern United States and Florida, a market where it competed with JetBlue Airways. It also operated flights between Florida and the West Coast, and from the Northeast to the west coast. Song's aircraft were fitted with leather seats and free personal entertainment systems at every seat, with audio MP3 programmable selections, trivia games that could be played against other passengers, a flight tracker, and satellite television. Song offered free beverages, but charged for meals and liquor. Both brand-name snack boxes and healthy organic meals were offered. The flight safety instructions were sung or otherwise artistically interpreted, depending on the cabin crew. In addition to crew uniforms designed by Kate Spade, customized cocktails created by nightlife impresario Rande Gerber and an in-flight exercise program designed by New York City fitness guru David Barton, the airline created its own distinct mark in the industry. Song's last flight took off on April 30, 2006. Service shifted to mainline Delta on May 1, 2006. On January 1, 2008, Delta began repainting the last aircraft bearing the Song livery into mainline Delta Air Lines colors.
