GPA, based in Tulsa Oklahoma flew a fleet of Doriner 328 and 728 jets from 2001-2003. The airline offered a high degree of service with Krispy Kreme donuts on morning flights, yum! Unfortunately, the hostile enviorment it launched in killed the airline off as it reached its 2nd birthday in 2004.It was founded as Ozark Airlines of Columbia, Missouri, which sold the operation to Great Plains.
