4). The New Look

Quantum was founded in 1982. The airline was formed by three executives, one a former Vanguard pilot, one a former Cardinal Pilot, and the head pilot of Quantum until 2008, when he became a full-time executive. The airline started as a small low cost airline in Memphis, TN. The core value of Quantum was and is frequency. The airline started flights to Baltimore, MD and Charlotte, NC on the same day with an MD-81. The airline eventually had focus cities (although the airline never had hubs) in Baltimore, Charlotte, Fort Lauderdale, Las Vegas, Memphis, New Orleans, and Salt Lake City. The airline acquired over 100 McDonnell-Douglas Super 80s, with the largest amount at one time in service being 125. Quantum had the most MD-88s ever acquired by any airline, as many prefered the 737-400/800 and the A320-200.
In 2004 Quantum looked at the recent changes in liveries among competitor airlines and decided to change their look. In 2005 this livery was introduced to the fleet on a new 737-800. Every aircraft delivered after 1995 was repainted in this livery, save for a few selected 737s and MD-80s. Every new aircraft after N828QT, the 737 first delivered in the new livery, was also painted in the new livery.
This MD-88 was delivered in 1999 and is expected to remain in service until May of 2017. There were only 5 MD-88s delivered to Quantum after this aircraft.
