If 9/11 never happened to air travel.....
In Australia, when travelling domestically there is no need to show ID to get through security or onto the plane. So you can book in any name, check in on line, go through security and board without showing any ID.
I don't think the ID check makes much difference. It's the taking off shoes and belts, removing all pocket contents and going through those full body scanners that is a PITA when travelling in the US.
