Damn, great idea. Instead of by hour, you could rent it in half hour slots. I am sure most couples would pay $500.00 for the privilege.
I did Newark to HK once on Continental. It took around 15 hours, that would come out to $15,000.
You may be able to turn a profit if your customers did not want clean sheets.
This would be the 7 to 8 mile high club though, not trying to be too graphic. LOL
