It normally costs about 100 dollars an hour to sit in a 747 seat, but you could sit for as long as you wanted for a fixed price, if you'd been on your toes. (Of course it's hard to sit when you're on your toes, but that's your problem.)
Other things you could have had: Rudder Trim Indicator Standby Airspeed Indicator N182UA - Tail Number Cut N171UA - Tail Number Cut Forward facing American flag cut-out Rear facing American flag cut-out Brake Pressure Indicator 747-400 Aluminum Cut-out Ram Air Inlet Oxygen Pressure Indicator Standby Attitude Indicator Standby Altimeter
Additionally, triple passenger and double passenger seats are available through a buy it now option, while a livery panel and single window cut have already been sold.
What is a livery panel?** The window would have been nice, easy to incorporate in your house or Winnebago.

It strikes me as the thing I would want least.
