Earlier quoted context omitted.
This is a bad faith question. The real question is, “Why were the airlines so poorly equipped to handle a cataclysmic event when the last one was only 19 years ago?” The answer is short term profitability. And the follow up question is, “Why would ANYONE bail any for-profit company out to the benefit of the shareholders only, ever?”
How could an airline company possibly be equipped to handle this kind of situation? If you want to be competitive on the market you need to lower costs and cut down on margins. You can't just have a big pile of money lying around "in case all flight is halted for a few weeks/months"
then the remaining market participants will figure out how to better account for such risks, which can no longer be considered rare (if they ever should have been).
