How Family Offices Structure Private Aviation: Ownership, Charter, and Fractional Explained

Aircraft Ownership: The Full-Control Model

Whole aircraft ownership — purchasing a jet outright or via a leasing structure — is the appropriate model for families flying 300+ hours per year on a consistent routing pattern. The economics of ownership break even against charter at approximately 250-300 hours of annual utilisation, assuming a midsize to large-cabin jet: below that threshold, the fixed costs of ownership (crew salaries, hangar fees, maintenance reserves, insurance, and management fees) typically exceed the equivalent charter cost. The primary advantages of ownership are: unlimited availability at any time; complete privacy and control over the aircraft interior, catering, and crew selection; the ability to customise the aircraft to the family's specific requirements (child safety systems, medical equipment, specific communication systems); and the elimination of the sourcing and booking process.

The operating cost structure of a mid-size jet (Gulfstream G450 or Global 5500 class) in European registration: crew (two pilots + cabin attendant) EUR 350,000-450,000 per year in total compensation; hangar fees (at a major business aviation hub such as Geneva, Le Bourget, or Farnborough) EUR 120,000-200,000 per year; maintenance and technical management (CAMO contract + scheduled maintenance reserve) EUR 300,000-500,000 per year depending on aircraft age and utilisation; insurance EUR 50,000-80,000 per year; management company fee (if outsourced to an aircraft management company) EUR 150,000-250,000 per year. Total fixed cost: EUR 970,000-1,480,000 per year before any fuel or landing fees. Variable cost (fuel, handling, overflight) adds approximately EUR 3,000-6,000 per flight hour depending on routing and aircraft type.

Tax and VAT considerations are the most complex aspect of aircraft ownership for family offices. In Europe, the VAT treatment of private aircraft is jurisdiction-specific: France applies a 20% TVA on aircraft purchases with complex rules around private versus commercial use; Switzerland has VAT exemption on certain commercial aviation structures; the UK post-Brexit has its own rules. The most common structure for European UHNW families is to own the aircraft through an Isle of Man or Jersey AOC (Air Operator Certificate), which enables commercial use of the aircraft (required for full VAT recovery in some jurisdictions) while maintaining the practical control of private ownership. Family offices should engage an aviation tax specialist before any ownership decision — the difference between optimised and unoptimised tax treatment on a EUR 30 million aircraft can exceed EUR 5 million.

Fractional Share Programmes: Flexibility with Structure

Fractional share programmes — NetJets, Flexjet, VistaJet's Programme, and XOJET (now part of Vista Global) — offer a middle path between ownership and on-demand charter. The client purchases a share in a managed aircraft (typically 1/16 to 1/4 of the aircraft, corresponding to 50 to 200 guaranteed hours per year), with the right to fly that share for a defined number of hours annually. The programme operator manages all aircraft operations, crew, maintenance, and scheduling. When the owned share is occupied by another fractional owner, the programme operator provides an equivalent or superior aircraft from its fleet.

NetJets — the oldest and largest fractional operator, founded by Warren Buffett's Berkshire Hathaway — operates over 750 aircraft in Europe and North America, making it the largest private aviation fleet in the world. A 1/16 share in a Gulfstream G550 (12.5 hours/year, the entry level) costs approximately USD 1.2-1.4 million to purchase; the annual management fee adds approximately USD 180,000-220,000; and the occupied hour rate adds approximately USD 8,000-10,000 per hour flown. The total annual cost for 50 hours (the minimum meaningful utilisation of a fractional programme) on a G550 approximates USD 650,000-750,000 per year, all-in. VistaJet's Programme (no share purchase, subscription model) offers comparable aircraft access with lower upfront commitment but higher per-hour occupied rates.

The primary advantage of fractional programmes over on-demand charter is guaranteed aircraft availability — the programme is contractually obligated to provide an aircraft (within the programme's call notice period, typically 4-10 hours). The primary disadvantage versus ownership is the absence of customisation: you fly a standardised programme aircraft, not your own configured jet. The primary disadvantage versus on-demand charter is the commitment: purchasing a fractional share involves a significant capital outlay that is illiquid, and the secondary market for fractional shares is thin. Family offices considering a fractional programme should model their actual utilisation over the previous 24 months before committing — the most common mistake is overestimating annual flight hours.

Jet Card Programmes: Pre-Purchased Charter Hours

Jet card programmes — offered by operators including NetJets, Wheels Up, XO, Sentient Jet, and Magellan Jets — allow clients to pre-purchase a block of flight hours (typically 25 to 100 hours) at a fixed per-hour rate, with guaranteed availability within a defined call notice period. Jet cards bridge the gap between fractional shares (long-term commitment, share purchase) and on-demand charter (no commitment, variable pricing). For families flying 50-150 hours per year with irregular patterns, a jet card offers price certainty and simplified booking at a modest premium over on-demand rates.

The jet card market has consolidated significantly since 2020. The relevant parameters to compare when evaluating programmes: per-hour occupied rate versus dynamic market pricing; peak/busy period surcharges (Christmas week, Super Bowl week, ski season); aircraft substitution policy (will the operator substitute a different aircraft if your contracted type is unavailable, and at what quality level); deadhead positioning charges (do you pay for the empty leg repositioning to your departure airport); and cancellation terms (how many hours notice to avoid a cancellation fee). FFGR Jets can evaluate specific jet card terms against its own on-demand pricing to help family offices determine whether a card represents genuine value versus their usage profile.

On-Demand Charter: The Flexible Default

On-demand charter — booking individual aircraft on a trip-by-trip basis from a broker or direct from an operator — is the appropriate model for families flying under 200 hours per year with variable routing patterns, or for families who maintain an owned or fractional aircraft but require supplemental capacity during peaks or when their primary aircraft is in maintenance. The advantages of on-demand charter are: zero fixed cost commitment, maximum aircraft type flexibility (every trip can use the most cost-efficient aircraft for the specific routing), and the ability to capitalise on empty leg opportunities when available.

The disadvantage of pure on-demand charter is price variability: the charter market is supply-demand driven, and peak weeks (Christmas-New Year, ski season, major events) see pricing 30-80% above off-peak rates. For family offices with consistent usage patterns, the price certainty of an owned or fractional programme may justify its higher fixed cost floor. For family offices with genuinely irregular usage (3-4 trips per year on unpredictable dates), pure on-demand charter is almost invariably the most cost-efficient approach.

FFGR Jets operates exclusively as an on-demand charter broker for its family office clients, without fractional shares or jet card programmes of its own. This structure ensures that FFGR Jets' aircraft recommendations are based purely on what serves the client's specific trip requirements — not on utilising inventory from a purchased share. For family offices considering their aviation strategy, FFGR Jets offers a complimentary usage analysis: based on the previous 24 months of flight data, FFGR Jets models the total cost of each programme type and presents a comparison that enables an informed decision.
