Charter aircraft, explained.
Private charter is priced and chosen by aircraft class. Quotes name real aircraft. Here's each class, what it runs per hour, and the specific models you'll actually see on a quote sheet.
Classes · smallest to largest
Turboprop
6-8 seats · $1,200–$2,800 per hour, est.
Turbine engine, propeller, shorter runways: slower than a jet, and the least expensive way to fly private on a short regional hop.
Very Light Jet
4-6 seats · $1,800–$3,200 per hour, est.
Jet speed and altitude in the smallest airframe that has them, for 4 to 5 people on a short trip with light luggage.
Light Jet
6-8 seats · $2,500–$4,500 per hour, est.
Domestic charter's most common airframe: full-size seats, a modest cabin, and the speed, range, and cost that fit the majority of trips.
Midsize Jet
7-9 seats · $4,000–$8,000 per hour, est.
Stand-up headroom, a galley, and baggage for a week: the step up when a light jet would be tight, for 6 to 9 or a longer leg.
Super-Midsize Jet
8-10 seats · $5,000–$10,500 per hour, est.
Coast-to-coast nonstop with a full stand-up cabin and 8 to 10 seats, at a cost well below a true heavy jet's.
Heavy / Ultra-Long-Range Jet
10-16 seats · $8,000–$14,000 per hour, est.
Ocean-crossing range and the largest cabins in charter: 10 to 16 seats, full stand-up, room to work, dine, and rest, at the top of the rate card.
