Correct me if I'm wrong but if UA decides not to renew, isn't Mesa left with a lot of leased airplanes with no home. This would force Mesa into BK, and leave all the contracts with other carriers up for cancellation.
Also, is JO and Mesa trying to avoid a Ch.7 BK since they have so many leased aircraft (no assets) and mounds of debt, which would not work well in a liquidation?
