Most airlines own half of their planes. So lets guess that Frontier owns 35 Airbus.... If they sell them at lets say 20 million a piece, which is a huge discount, thats $700 million. I would say thats a nice return on a $108 million dollar investment. Anything is possible. Look at Southwest and ATA. They bought ATA for under 10 million i think, sold off everything, made a nice profit, and kept their slots and routes.
