Time saving - this is one of the most significant reasons for using private aircraft. Depending on your program you can have an aircraft ready in just a few hours. You can arrive at the airport just minutes before your scheduled departure time, fly directly to your destination (without any layovers), make productive use of your time onboard, avoid overnight stays (saving hotel $ as well as time), avoid waiting in lines at the airport, land at over 5,000 airports in the US and so be closer to your destination. All of this can provide significant savings in both productive time and in dollars. Productivity - the time savings above provide significantly more productive time, both onboard and before and after your flight. You and your staff can make the most of the travel time to talk business or work with customers, suppliers or partners.

Operating leases are generally short-term (less than 10 years in duration), making them attractive when aircraft are needed for a start-up venture, or for the tentative expansion of an established carrier. The short duration of an operating lease also protects against aircraft obsolescence, an important consideration in many countries due to changing noise and environmental laws. In some countries where airlines may be deemed less creditworthy (e.g. the former Soviet Union), operating leases may be the only way for an airline to acquire aircraft. Moreover, it provides the flexibility to the airlines so that they can manage fleet size and composition as closely as possible, expanding and contracting to match demand.
In 1999, Bombardier introduced a new type, the Challenger 300, as part of the growing "super-midsize" private jet class. The Challenger 300 – and later Challenger 350, introduced in 2013 – competes with aircraft including the Cessna Citation X and Gulfstream G280. The Challenger 350 carries passengers 3,200 nautical miles non-stop at a cruise speed of Mach 0.80, and features the widest, purpose-built super midsize aircraft cabin with both a flat floor, and in-flight baggage access.
Cessna simultaneously developed the Citation Mustang,[22][19][20] a six-place twinjet (2 crew + 4 passengers), followed by the Embraer Phenom 100[22][19][20][21] and the Honda Jet.[19][21] They have a maximum takeoff weight lighter than the FAR Part 23 12,500 pounds limit, and are approved for single-pilot operation. They typically accommodate 5-7 passengers over a 965 nmi average range, with a $3.6M mean price. Some VLJs such as the Eclipse and Mustang have no or limited lavatory facilities.[23]

About 70% of the fleet was in North America at the end of 2011. The European market is the next largest, with growing activity in the Middle East, Asia, and Central America.[8] In 2015 the total airplane billing amounted to US$21.9 billion, and 718 business jets were delivered to customers across the globe : 199 (27.7%) by Bombardier Aerospace, 166 (23.1%) by Cessna, 154 (21.4%) by Gulfstream Aerospace, 120 (16.7%) by Embraer and 55 (7.7%) by Dassault Falcon.[9]
