Of course nobody will go to zero, I was just using that as a reference point. Airlines with higher debt and operating expenses will need to keep more cash to service that or they will be bankrupt. There was some pilot math here, I’m no accountant but these should be pretty accurate, if not feel free to correct. It was also a bit tricky to be precise being that so much has changed so fast. UAL and SWA have had stock sales recently, which we’re included in these numbers. It appears Spirit announced that today as well....so that could further change things. DAL has a market cap more than double UAL, and triple AAL. They may choose to dilute that to raise liquidity. The debt burden of a company like AA was barely sustainable during good times. With severely reduced revenue it makes you wonder how they plan to navigate the next few years without a bankruptcy to lower debt levels and get rid of a portion of their fleet.
