Spirit chairman Robert Milton said a deal with Frontier still makes logical sense, but Spirit has had inquiries from other airlines. He said Spirit has the right executive team in place, and that by going through the bankruptcy process now it can gain an advantage, whether it remains on its own or combines with another carrier. “If you’re smart, get on with it, do it with a sharp knife and not a blunt instrument, you come out in a far better position,” he said.
