20-30 minutes for checked luggage. 20-30 minutes for security groping.
20-30 minutes waiting for that idiot to find his seat.
20-30 minutes waiting for luggage or the carousel.
Using this as an example because I make this trip often: I can fly Cincinnati, OH to Charlotte, NC on a VIP airline for $500 round trip. I drive my car right up to the plane, and there is a rental car waiting for me at the plane exit on the other side. The entire plane is first class only. There is no baggage check, no TSA, no nothing. I can walk on to the plane 5 minutes before takeoff.
