Greybull didnt exactly do a great job at Monarch, Delta had money from the U.S Government and are not allowed to use that for VA. Perhaps VA's announcement of having the administrators on standby or advising, is to show the Government they have done everything they can. Insolvency laws are to have proposed changes put through parliament next week, which might benefit VA.
It will depend on the cash in the bank, daily cash flow for how long they have left. The new CEO is a good guy with a finance background. Hopefully VA have done enough to get a loan from the government with the recent cut backs and restructure the business model for the future, perhaps diversifying in cargo. Many third party suppliers and their employees would be affected if they went.
VA have some really good people, all are working hard to help the company as much as they can. I wish the best outcome for everybody at VA, to get through this and continue to compete against BA.
