Japanese leveraged lease: A JLL requires the establishment of a special purpose company to acquire the aircraft, and at least 20% of the equity in the company must be held by Japanese nationals. Widebody aircraft are leased for 12 years, while narrowbody aircraft are leased for 10 years. Under a JLL, the airline receives tax deductions in its home country, and the Japanese investors are exempt from taxation on their investment. JLLs were encouraged in the early 1990s as a form of re-exporting currency generated by Japan's trade surplus

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.
Fractional ownership of aircraft involves an individual or corporation who pays an upfront equity share for the cost of an aircraft. If four parties are involved, a partner would pay one-fourth of the aircraft price (a "quarter share"). That partner is now an equity owner in that aircraft and can sell the equity position if necessary. This also entitles the new owner to a certain number of hours of flight time on that aircraft, or any comparable aircraft in the fleet. Additional fees include monthly management fees and incidentals such as catering and ground transportation. In the United States, fractional-ownership operations may be regulated by either FAA part 91 or part 135.
