Airline Supply Chain Has Become a Boardroom Issue: From Procurement Savings to Operational Resilience
Why aircraft availability, MRO capacity and supply chain resilience are becoming critical drivers of airline profitability
For decades, airline procurement was largely viewed through the lens of purchasing: negotiate harder, consolidate suppliers, optimise inventory and reduce unit costs.
That definition is no longer sufficient.
Across the aviation industry, shortages of engines and critical components, extended maintenance turnaround times, OEM delivery delays, limited MRO capacity and shortages of qualified technical personnel are increasingly affecting airlines’ ability to operate the capacity they have planned and sold.
As a result, aviation supply chain management has moved from a primarily transactional activity to a strategic determinant of aircraft availability, operational reliability, customer experience and airline profitability.
This was the central conclusion of Clear Lift’s July Executive Committee discussion on Supply Chain, Procurement & Fleet Availability, led by our new Expert Partner in Supply Chain, Ruyman Gallardo. The discussion brought together perspectives across procurement, MRO, fleet, operations, finance, commercial strategy and airline transformation.
For CEOs and Boards, the implication is important:
The question is no longer simply: “Are we buying well?”
It is increasingly:
“Do we have the aircraft, engines, components, maintenance capacity and organisational visibility required to deliver the operation — and protect the revenue — we have committed to?”
The economics of supply chain have changed
Aviation is fundamentally different from a conventional supply chain.
Every component must meet demanding requirements around traceability, certification, configuration and airworthiness. Demand is partly unpredictable. Many components are low-volume but extremely high-value. Supply can be concentrated among a relatively small number of OEMs and approved providers.
Most importantly, the operational consequences of failure can be disproportionate.
A relatively inexpensive unavailable component can keep a multimillion-dollar aircraft on the ground, potentially creating cancellations, passenger disruption, reaccommodation costs, crew consequences and lost revenue.
As Ruyman’s Executive Committee presentation summarised:
“In aviation, the cost of not having a part can be significantly higher than the cost of the part itself.”
This changes the economics of procurement.
The cheapest component, repair agreement or inventory strategy is not necessarily the lowest-cost solution once aircraft downtime, operational disruption and lost revenue are incorporated into the equation.
That distinction should matter to every CFO, COO and CEO.
Aircraft availability is becoming the real procurement KPI
Traditional procurement organisations naturally measure savings, purchase-order performance, contract compliance and supplier pricing.
Those measures remain relevant.
But they do not necessarily tell management whether the supply chain is creating value for the airline.
A more strategic KPI framework starts with business outcomes:
aircraft availability;
technical dispatch reliability;
operational completion;
revenue protected;
customer disruption avoided;
material-related AOG events;
maintenance turnaround time; and
total cost of aircraft downtime.
Supplier on-time delivery, repair turnaround time, inventory accuracy and purchase-order cycle time then become contributors to those outcomes rather than objectives in themselves.
This represents an important shift in airline performance improvement.
A procurement organisation can exceed its annual savings target and still destroy value if aircraft remain grounded because the right engine, component or maintenance slot is unavailable when required.
Activity measures how busy the organisation is. Outcomes measure whether it is creating value.
From reactive procurement to operational resilience
The strongest airlines are consequently moving from reactive supply chain management towards proactive operational resilience.
That requires a different management model.
Procurement cannot optimise independently from Engineering. Engineering cannot plan independently from Fleet. Fleet decisions cannot be separated from Finance, Operations or Network requirements.
Clear Lift’s Executive Committee identified several priorities: protecting aircraft availability, securing engine maintenance capacity earlier, improving end-to-end supply chain visibility, strengthening supplier relationships, integrating procurement with operational planning and improving inventory forecasting.
This is increasingly where airline operational efficiency and airline cost reduction intersect.
Reducing inventory indiscriminately may improve working capital today while increasing AOG exposure tomorrow.
Outsourcing may reduce fixed cost while increasing dependence on third-party capacity.
Insourcing may increase control but require greater capital investment.
A hybrid model can provide flexibility but demands stronger governance.
There is therefore no universal “best” supply chain structure. The appropriate model depends on fleet scale, operational criticality, market maturity, risk exposure and total lifecycle cost.
For Boards, the objective should not be minimum procurement cost.
It should be the right balance between cost, control, capital and resilience.
Critical paths matter more than individual transactions
One of the most important concepts discussed during our Executive Committee was the critical path.
Consider an AOG event.
Identifying the required component is only one part of the recovery process. Troubleshooting, material availability, commercial approval, transport, customs, installation, testing and aircraft release can all determine when the aircraft actually returns to service.
The same principle applies to heavy maintenance and engine shop visits.
For an engine event, spare-engine availability, confirmed shop capacity, disassembly findings, life-limited parts, material availability, assembly and test-cell release may all sit on the critical path.
The management lesson is simple:
A supplier delivery date is not necessarily an aircraft return-to-service date.
Airlines therefore need visibility across the entire process rather than optimisation of isolated functions.
This is where airline data analytics, predictive airline operations and aviation digital transformation can become particularly valuable — provided technology connects operational decision-making rather than simply adding another layer of reporting.
The fleet backlog is multiplying the challenge
Supply chain pressure also needs to be understood within the wider fleet environment.
During Clear Lift’s July Executive Committee, the group reviewed the commercial aircraft backlog following the Farnborough International Airshow.
The figures presented to the Committee were significant: as of Q2 2026, Airbus’ backlog stood at approximately 9,222 aircraft, while Boeing’s was approximately 6,200. At prevailing production rates, the Committee estimated this represented roughly 11 years of backlog for Airbus and 10 years for Boeing.
That has consequences well beyond aircraft manufacturers.
When replacement aircraft arrive later than expected, airlines may need to retain existing aircraft longer, extend leases or modify fleet plans. Older fleets can, in turn, require additional maintenance, material and engine support.
That demand enters an MRO and supply chain ecosystem already facing capacity constraints.
The consequence is a reinforcing cycle:
Aircraft delivery delays → longer fleet retention → greater maintenance demand → increased pressure on engines, components and MRO capacity → greater operational risk.
This is why fleet strategy and supply chain strategy increasingly need to be considered together.
The industry has less margin for error
The challenges identified during the Executive Committee were not isolated.
They included aircraft delivery delays, engine durability and shop capacity constraints, parts and material shortages, technical workforce shortages, supplier concentration, fragmented data and geopolitical and logistics disruption.
Each can be managed individually.
The strategic problem emerges when several occur simultaneously.
An aircraft delivery delay may require an older aircraft to remain in service. That aircraft may require an engine shop visit. The shop visit may be extended by unavailable material. A spare engine may not be available. An alternative supplier may not exist.
Suddenly, what began as a procurement issue becomes a capacity, network, revenue and customer problem.
For executive teams, this demands greater cross-functional visibility and faster decision-making.
Data and predictive capability can change the equation
There is also an important technology dimension.
Predictive maintenance, improved demand forecasting, real-time fleet visibility and integrated airline operational intelligence can allow management teams to identify risk earlier.
The objective is not technology for technology’s sake.
It is better decisions.
Can an airline identify an emerging engine constraint months before it affects the schedule?
Can maintenance planning anticipate material requirements before an aircraft enters a heavy check?
Can Procurement see upcoming operational demand early enough to secure scarce capacity?
Can Finance quantify the trade-off between additional inventory and the expected cost of aircraft downtime?
Can Network and Fleet Planning understand how technical availability could affect planned capacity?
This is where AI for airlines, airline decision intelligence and predictive airline operations can generate real economic value — by connecting technical information with commercial and financial consequences. These are also among the strategic digital themes Clear Lift has identified as increasingly important for AI-driven search and airline transformation.
What should CEOs and Boards be asking?
Supply chain resilience should increasingly form part of executive performance discussions.
Five questions are particularly important:
Do we know which supply chain constraints could materially affect next season’s capacity?
Are critical engine slots, repair capacity, materials and technical resources being secured sufficiently early?
Are procurement KPIs connected to aircraft availability, revenue protection and operational reliability?
Can Finance, Operations, Engineering, Fleet and Procurement see the same risks and make decisions from the same information?
Are we optimising purchase price — or total economic value?
The answers reveal whether procurement remains principally transactional or has evolved into a strategic capability.
Resilience is becoming a competitive advantage
The conclusion from Clear Lift’s Executive Committee was clear: procurement has become a strategic function directly influencing airline profitability and operational performance, while supply chain resilience has become as important as traditional cost efficiency.
Leading airlines will not eliminate supply chain disruption. Many of today’s constraints sit beyond any individual carrier’s direct control.
What they can control is how early they identify exposure, how quickly they make decisions and how effectively their organisations execute across functional boundaries.
Ruyman’s presentation distilled the transition well: manage supply chain around aircraft availability rather than procurement savings; control the complete end-to-end critical path; integrate engineering, maintenance, procurement, inventory and operations; secure scarce capacity in advance; use predictive maintenance and analytics; and balance efficiency with resilience.
“The strongest aviation supply chains are not necessarily those that purchase at the lowest cost. They are those that understand operational criticality, identify risk early and act before the aircraft — and ultimately the customer — is affected.”— Ruyman Gallardo, Expert Partner – Supply Chain, Clear Lift
And this is precisely where the discussion becomes broader than procurement.
“For airline leadership teams, supply chain resilience is now part of commercial and financial strategy. Every aircraft that cannot operate represents capacity that cannot be sold and revenue that cannot be delivered. The opportunity is to connect procurement, operations, maintenance, fleet, finance and commercial decisions before constraints become disruptions. At Clear Lift, our role is to bring hands-on airline experience to that process — analyse the exposure, align the organisation and support execution.”— Nicolas Rhoads, Founder & Principal, Clear Lift
From insight to execution
For airlines looking at airline performance improvement, airline profitability improvement, operational efficiency or cost transformation, supply chain can no longer be treated as a specialist function operating behind the scenes.
It has become part of the airline’s ability to deliver its business plan.
At Clear Lift, our approach to airline consulting and aviation advisory services is built around former airline executives with hands-on operating experience. We work with leadership teams to connect strategy with execution — identifying where operational, commercial and financial value can be protected or created.
Because in today’s constrained aviation environment, competitive advantage will increasingly belong to airlines that can see risk earlier, decide faster and execute across the organisation before disruption reaches the aircraft.
We have been there. We have led the change.
