I flew last week. I didn’t need any sort of government permissions or registrations to do it. I just bought a ticket, went to the airport, walked through security, and got on the plane.
You needed a valid government issued photo ID.
Walked through security? Just like that? Not since September 11, and I fly a lot, and into little burgs like Presque Isle, Maine. Shoes off, no liquids over 3 ounces, blah, blah, blah.
The government controls you no matter what your mode of transport is.
