“A heavy debt load, weak cash flow associated with a significant decline in global air cargo demand and an employee lawsuit are raising questions about the ongoing financial viability of Western Global Airlines, an all-cargo carrier with a fleet of 21 aging aircraft that counts retailer Amazon as its top customer.

A review of flight tracking sites indicates Western Global is winding down operations, with the majority of aircraft having returned to home base at Southwest Florida International Airport in Fort Myers or its maintenance center in Shreveport, Louisiana.

Bloomberg, citing anonymous sources, reported Saturday that Western Global Airlines is considering whether to file for bankruptcy protection in response to a cash crunch and that executives are meeting with creditors about a financing lifeline.”
