Since there seem to be people willing to go during the early phases of recovery, and others that don't want to - seems like the charter companies would have a win/win by simply allowing those that want to cancel do so. A nominal administrative fee seems reasonable.

"Forcing" people to go this early against their better judgment (by not refunding fully paid trips) seems like a really bad idea to me. Those folks are going to be disappointed in their vacations, and likely to report to the public how terrible things were.

Much better business practice to get the folks that don't mind roughing it down there during the early phase, as those are the ones most likely to report back about how great things are looking.
