— THE PROBLEM
Growth is the complication.
Flair Airlines flies a growing fleet of Boeing 737 aircraft to 25 cities across Canada, the United States, Mexico, the Dominican Republic and Jamaica, positioning itself as the country’s most reliable and greenest carrier. Its business model depends on adding capacity efficiently, and in commercial aviation, adding capacity means adding leases.
That ties lease accounting directly to growth rather than leaving it beside the business as a compliance task. Under IFRS 16, every aircraft Flair brings into the fleet lands on the balance sheet as a right-of-use asset and a lease liability, each with a schedule to maintain, a remeasurement to watch for, and a disclosure to produce. A process that works for a handful of aircraft may not hold at the next tranche.
“For an airline, aircraft leases are one of the most significant and complex areas of accounting.”
Naveed Kamran — Assistant Controller, Flair Airlines
— THE COMPLEXITY
Why aircraft leases are different.
Aviation produces lease structures that general-purpose accounting tools were never designed to hold. Airframes and engines can sit on separate agreements with separate terms. Payments vary with hours flown or cycles operated. Maintenance reserves and supplemental rent have to be classified correctly rather than swept into the liability. Fleet financing is often denominated in US dollars while the reporting entity runs in Canadian dollars. Any one of these can be handled manually; together, at the pace of fleet expansion, they cannot.
WHAT AN AIRLINE LEASE PORTFOLIO DEMANDS
HOW BLACK OWL HANDLES IT
Aircraft and engine leases on separate terms
Tracked as distinct leases with their own terms, schedules and journal entries
Maintenance reserves and supplemental rent
Classified and scheduled separately from the lease liability
Variable payments tied to hours or cycles
Recognized in the period incurred, outside the liability measurement
USD-denominated leases, CAD functional currency
Foreign currency remeasurement handled in-system each period
Sale-leaseback transactions
Modelled against IFRS 16 requirements rather than worked around
Renewal, extension and return conditions
Reassessments applied without rebuilding the schedule
New aircraft joining a growing fleet
Leases onboarded as the fleet expands, without a parallel spreadsheet
— WHY BLACK OWL
What Flair was looking for.
Flair evaluated the market for a platform that could carry the complexity of an airline lease portfolio and keep carrying it as the fleet grew. The requirement was not one-time IFRS 16 adoption. It was a repeatable monthly process the finance team could rely on, with reporting an auditor would accept without reconstruction.
“Black Owl took the time to understand the nuances of our lease accounting requirements and the realities of our business. Their team delivered a solution that supports our IFRS 16 reporting needs and gives us a more structured process for managing lease accounting going forward.”
Sumanth Rao — CFO, Flair Airlines
Black Owl was selected for its willingness to work through the specifics of Flair’s portfolio rather than fit it to a template. It is the same approach that led Occidental Petroleum to replace a system it had built in-house with our platform. In both cases the requirement was the same underneath: a lease sub-ledger that holds the real structure of the business, not a simplified version of it.
— THE RESULT
A structured monthly close.
Live since Jan 2026
Schedules, journal entries and disclosure reporting all drawn from one source — the lease sub-ledger.
Flair went live on Black Owl in January 2026. The finance team now runs lease accounting as a structured monthly process: schedules maintained in one place, journal entries generated by the system, and disclosure reporting drawn from the same source as the accounting rather than assembled separately.
“Black Owl has strengthened our lease accounting framework, improved accuracy, and enhanced transparency across our financial reporting while maintaining full compliance and audit readiness.”
Naveed Kamran — Assistant Controller, Flair Airlines
— CONCLUSION
Every aircraft Flair adds to its fleet eventually lands on its balance sheet. Flair now runs a lease sub-ledger that keeps pace with the fleet, built for the complexity of its aircraft leases today and ready for the aircraft still to come.
“We are proud to support Flair with a system that provides strong accounting functionality, accurate reporting, and a process built for finance teams that need confidence in their lease accounting every month.”
Greg Kautz — CEO and Co-Founder, Black Owl Systems
