Air Taxi's
If you sit down and add up all the expenses for four people to fly first class within a 1200 mile radius it makes sense to use a Dayjet service. Not only will you save almost a full day at either end of the trip since you don't have the hassle of the airport and TSA but you could be flown directly from your home to the destination for little more than four first class airfare tickets.
I'll bet the pilots earn more too.
