I don't think this analogy is applicable. The government hasn't banned air travel, and the drop in demand is more of a second order effect as the result of minimizing potentially detrimental behavior (spreading the virus).

In general I don't believe the government is required to compensate businesses if regulation results in loss of business and possibly the loss of the business. As an example, look at CFC bans and fuel/emissions regulations. A company may suffer a loss and/or go out of business because of a regulation, but they can't demand compensation for that from the government.

The government has, in fact, banned most international air travel.

The US government hasn't banned most international travel for legal residents. There's a list of restricted countries that require legal residents coming from them to only go to specific airports with enhanced entry screening.

It has banned entry by foreign nationals from those countries, but I wouldn't call that banning most international travel.
