We prefer to finalize our itinerary, plane and crew at least a week in advance. We did not get things completely final until the day of the actual flight. Secondly, we prefer to pay post-flight rather than pre-flight. You were able to make an exception in our case which was appreciated. Lastly, the quality of the catering service from STT was atrocious. It was inedible.
No matter what company you're flying with, be sure to ask if there two pilots or one. (Though two pilots are standard on commercial flights, regulations vary for private planes of all sizes.) It also helps to ask if the operator owns the plane—typically, companies that own their planes offer better service. Never forget to ask about daily minimums and taxi fees. "If the hourly rate is $9,000 and you have a single 40-minute flight, you might assume you are going to pay $6,000," says Doug Gollan, creator of PrivateJetCardComparisons.com. "But if your provider has a daily minimum of 1.5 hours, you are going to actually be charged $13,500, plus taxi time, which in my comparisons I have found varies between being included and up to 12 minutes per segment."
You will be told how much the hold can take on your chosen aircraft and can upgrade if you feel more space is needed. This will generally be far more than that of a commercial airline. You may also need to upgrade if carrying things like golf clubs and skis. If travelling with a gun, you will need to provide a license and the gun and ammunition must be kept separate. It is then at the captain’s discretion whether it can be on board.
