Because the OP was about angry customers, not exclusively about death threats. Of course people are angry, because they in many cases actually lost something. In many companies, you book leave months out and cannot change it. They were still promising there would be no more delays with less than a month to go, even saying only a natural disaster would stop them. Now we know that's a lie, and they were deliberately misleading customers.
