OK, so a quote of $12,000 to go to Florida may not seem like such a good deal, but you have to look at what you are paying for.
Leave at the time you want. No long lines to take your shoes off at the security checkpoint. Drive right out to the aircraft.
Have your bags carried onto the aircraft and not thrown onto a baggage loader. First class service en route.
Have your car driven to the aircraft steps on arrival. Be on your way within 5 minutes.
Wonder why you can't get that kind of personal service even flying first class on the airlines any more? How much did you pay for your airline ticket?
