Aircraft Partnership Software: Split the Costs, Share the Bookings

A shared aircraft runs on two agreements: who flies when, and who pays what. Pilot-Next keeps both in one place for aircraft partnerships, syndicates and co-ownership groups — owners book the aircraft, log Hobbs or Tacho time after the flight, and each flight is priced and booked to that owner's own account. Below: what sharing does to each owner's cost, worked out for one to six owners, and how fourteen partnership platforms compare.

How do co-owners split the costs of a shared aircraft?

Most aircraft partnerships split the costs in two parts. The fixed costs — hangarage, the annual inspection, subscriptions, administration and, at low utilisation, the engine overhaul reserve — are shared equally as a fixed share per owner, and every owner pays a rate per flight hour for fuel, oil and maintenance. For a Cessna 172S Skyhawk SP in which each owner flies 40 hours a year, the fixed share per owner falls from €9,510 ($11,947 at a US price level) for a single owner to €2,378 ($2,987 at a US price level) with four owners, while the rate per hour stays at €153 ($103 at a US price level). Depreciation and insurance come on top, because both depend on what the aircraft cost.

Indicative figures, computed with the same model as the aircraft ownership cost calculator; data last updated 16 September 2026. Fixed costs here are hangarage, the annual inspection, navigation database, charts, weather and administration, plus the engine overhaul reserve while the calendar limit comes first. Depreciation and insurance are left out because both follow the price of one particular aircraft; the calculator adds them back.

One line moves between the columns. The engine of the Cessna 172S Skyhawk SP has a 2,000-hour overhaul interval and a 12-year calendar limit, and whichever comes first applies. Up to 4 owners (160 hours a year) the calendar comes first, so the overhaul reserve is a fixed cost shared by the owners; from 5 owners (200 hours a year) the hours come first and the reserve moves into the rate per flight hour. That is why the rate per hour rises slightly while the fixed share drops.

Open this example in the calculator to change the aircraft, the number of owners, the hours, or any single cost line — or to see whether renting the aircraft out would cover part of the fixed costs.

How much does it cost to co-own a plane?

With four owners who each fly 40 hours a year, a Cessna 172S Skyhawk SP costs each owner about €8,498 ($7,107 at a US price level) a year, or €212 ($178 at a US price level) per hour they fly, before depreciation and insurance. A single owner flying the same 40 hours pays €15,630 ($16,067 at a US price level) a year, or €391 ($402 at a US price level) per hour. These are indicative figures from the Pilot-Next aircraft ownership cost calculator, at a European price level with the US price level in brackets.

How do co-owners share the bookings fairly?

Partnerships write booking rules into their agreement: how far ahead an owner may book, how long a booking may run, how weekends and holidays are shared, and when an unused booking has to be released. Those rules only hold if nobody can book over someone else, so the scheduling system has to enforce it. In Pilot-Next a confirmed booking cannot overlap another confirmed booking on the same aircraft, and a partnership can require an administrator to approve bookings before they are confirmed.

Owners who switch on calendar integration get a calendar invite when a booking is confirmed, an update when it moves and a cancellation when it is cancelled. More on the scheduler itself: aircraft scheduling software for clubs, partnerships and rental.

How do co-owners settle up after each flight?

After the flight the pilot logs the Hobbs or Tacho time against the booking, and the flown hours are priced at the partnership’s rate per hour, or charged per booking. In Pilot-Next that charge is invoiced and booked to the pilot’s own account balance, next to the contributions an administrator records as deposits, so every owner sees what they have paid and what they owe without a shared spreadsheet.

Two choices shape the hourly charge: whether to bill on Hobbs or Tacho time, and why settling per booking beats settling per flight. Rates can differ per aircraft and per pilot, and extra charges you define — a landing fee, say — are asked for when the flight is settled.

Which software is built for aircraft partnerships?

Of the platforms we read on their own websites on 26 September 2026 and 29 September 2026, fourteen offer co-owners a shared schedule and a way to split the costs: Pilot-Next, Coflyt, Flyout, FlyClub, Pilot Partner, 5-by-5, PlaneBud, CoOwner, syndik8, FlyerOS, Spliyt, Wingtrex, Squawkd and FlightBoard. They differ in how they charge — per aircraft with unlimited members (Coflyt Plus, Flyout, FlyClub, FlyerOS, Wingtrex), per member with a cap per aircraft (5-by-5), per group by number of owners or partners (CoOwner, Spliyt, syndik8), by number of aircraft with a free level up to five (PlaneBud), by plan with a fee for every extra aircraft (Squawkd, FlightBoard), per aircraft plus a paid logbook for every member (Pilot Partner), or per company with a pilot limit (Pilot-Next) — and in whether they turn each owner’s flown hours into a charge.

Read on each vendor's own website on 26 September 2026 (5-by-5, PlaneBud, CoOwner, syndik8, FlyerOS, Spliyt and Wingtrex on 29 September 2026); quotes are the vendor's own words. “Not stated” means the site does not say — not that the feature does not exist. Features and prices for twelve platforms, including club-oriented ones, are in the flying club management software comparison, with a page per platform such as Pilot-Next vs Coflyt and Pilot-Next vs Flyout.

How much does Pilot-Next cost for an aircraft partnership?

A partnership of up to 5 pilots sharing one aircraft fits the BASIC plan at €9 a month, billed annually. PRO covers 2 aircraft and 10 pilots for €18 a month and ULTRA unlimited aircraft and pilots for €45 a month. A single owner can use SOLO free forever for 1 aircraft and 1 pilot, and SOLO asks for no payment details.

What should an aircraft partnership agreement cover?

At least the number of shares and what a share costs to buy into, how fixed and variable costs are split and how often the hourly rate is reviewed, the booking rules, who decides on maintenance and up to what amount, the insurance and who may fly the aircraft, and what happens when an owner wants to leave: how a share is valued and who may buy it. This is a checklist, not legal advice; have the agreement itself drawn up for your country.

Which inspections the group has to plan for, and how the 100-hour and the annual combine, is on aircraft maintenance tracking.
