Fifteen minutes prior to departure is a good guideline for arriving at the airport for a chartered flight. However, since you chartered the aircraft, there is no risk of missing your flight! Since you know all the people on the aircraft with you, there are no security checks and no line-ups! If you and everyone in your party arrive early, the flight departs early. If you or anyone in your party runs into some unforeseen delay, the aircraft will not depart until you, the customer, instructs the flight crew to leave. A courtesy call to our main office line is all we ask of delayed passengers.
