It doesn't work like that sadly. Profits and loss do not necessarily have an impact on liquidity (cash on hand). A good example of this is the write-off lots of airlines did on their planes. This has a huge impact on profits, but no direct impact on liquidity.

On the other hand there are also things that impact the liquidity of the company, but do not affect the profit. The best example for airlines are pre-paid tickets. Airlines are only allowed to recognize these as profit after the service (i.e. flight) is delivered. Until that time they will have an asset (cash) on their balance sheet, which is off=set by a liability to deliver this service. For Aegean this means that a lot of the cash they had in April was for tickets that they had to cancel. They now have to pay this money back to those customers, which would be a huge drain on their cash. But it won't affect their profit in any way, because liabilities would be reduced by the same amount as the assets (cash).

So while their loss might be 'only' 205mln, their decrease in liquidity could be way higher.
