A public charter is one in which a tour operator rents the aircraft and advertises and sells seats to members of the public, either directly or through a travel agent. In the case of public charters, the flight must be filed with the U.S. Department of Transportation, and the tour operator must supply a charter prospectus. The tour operator also must assume a legal responsibility to provide the transportation service, and must abide by DOT requirements for the protection of the clients' money. Public charters often operate only seasonally, and are often sold as part of a vacation package deal, although spare seats may be offered at bargain prices.
The very light jet (VLJ) is a classification initiated by the release of the Eclipse 500, on 31 December 2006, which was originally available at around US$1.5 million, cheaper than existing business jets and comparable with turboprop airplanes. It accompanied a bubble for air taxi services, exemplified by DayJet which ceased operations on September 2008, Eclipse Aviation failed to sustain its business model and filed for bankruptcy in February 2009.
An affinity charter is slightly different in that, although all of the passengers are affiliated with a specific business, group or organization, each pays his own air fare. The passengers might sports or music fans traveling to a special event, or a bunch of friends going on vacation. With this type of charter, none of the seats can be sold to members of public.
With a dry lease, the lessor provides the aircraft without crew. These arrangements are favored by leasing companies and banks, and require the lessee to put the aircraft on its own AOC and provide aircraft registration. Dry leases usually cover a term of no less than two years. Lessees must comply with conditions regarding maintenance, insurance, and depreciation, and other requirements that may be affected by geographical location, political circumstances or other factors.
