Your beginning to sound Trump like (HUGE). I didn't realize it was a human right to fly.
Better go talk to your deity about that, and tell those people at the airport, that they need to donate their time, as it is a human right, so they shouldn't be making money off of it, either.
He refused an order, now whether it was lawful or not, to be honest should be up to a court to decide. It was a mistake to tell the cops no, as they have the right to use force for their safety and to get the job done. Lawful gets decided after the fact in a court. (law part, verses enforcement parts) Besides the lawsuit against the airlines, I expect he has a criminal court appearance now for failure to comply, which could end up placing him on the government no fly list.
Good question. If they know the airlines may need x number of seats, then why don't they reserve some seats on the plane.
