In general terms I would agree with the rampant capitalists on here but on this occasion the crisis for airlines is because the government has shut down travel. (I am not commenting on why, only that they have.) I think, therefore, the government might have some responsibility to support them through the crisis, if only with repayable loans.
If the government wants the airlines to suspend already proposed dividends then maybe they should suspend the rules, simple.
I understand the airlines are not at the absolute top of the priority tree just at the moment but the employees and the public will surely punish the government if their jobs and their mobility are permanently destroyed
