In 1985, UA had look at old Frontier for possible buy-out. Frontier was really in dire straits at that time. UA bought some Frontier's 737s & all the MD-80s. Old Frontier finally went under & UA got all their planes back. UA then leased the MD-80s to AirCal...AirCal returned the ships, and UA finally sold them to Continental. Regards.
