Surprisingly, not as much as you might think. Larger private jets that can carry more people will generally cost more per hour to charter than smaller aircraft with fewer seats. However, beyond that, the only extra charge per passenger is a standard fee, which varies based on your trip.
For domestic travel within the U.S., this fee is a domestic segment tax of $4.30 per passenger, per leg of the trip. This “head tax” increases to $18.90 per passenger, per leg for international flights. Additionally, there is a $9.50 fee per passenger, per leg for flights departing from Alaska or Hawaii. Other countries have similar mandatory fees, so consult your charter professional about the specific fees for your trip.
Italian luxury taxes depending on the of miles might be €50, €100 or €200 per passenger per route.
Other factors to consider when bringing on board additional passengers are: VIP lounges, Catering, and the difference between private jet and commercial taxes if the number of passengers exceeds 13.
It’s always best to inform your charter professional in advance about the number of passengers traveling with you. This helps avoid any last-minute surprises when boarding and allows the flight crew to complete all necessary preflight activities, including weight and balance calculations on smaller aircraft.
