Airline MRO Sourcing: A Smarter Way to Push Back on Rising Fuel Costs

Fuel costs are keeping a lot of airline executives up at night right now, and for good reason.

Jet fuel eats up roughly a quarter of what it costs to run an airline. When prices stay high, margins shrink fast. And if that weren't enough, supply chain headaches, parts shortages and aging fleets are pushing maintenance costs higher at the same time. It's a tough combination.

So, what do procurement leaders do? Find savings without cutting corners on safety or reliability.

The usual playbook (renegotiating contracts, squeezing suppliers, stretching payment terms) still has a role. But if your procurement team is already mature, chances are you've already picked most of that fruit. The bigger opportunity is somewhere else: Maintenance, Repair and Overhaul (MRO) sourcing.

Specifically, rethinking how you source Line Replaceable Units (LRUs) and Consumables & Expendables (C&E) could unlock real savings and make your supply chain a lot more resilient in the process.

Why MRO Has Been Overlooked

For years, OEMs basically ran the show in airline MRO sourcing. That gave airlines consistency, but it also meant limited competition and limited leverage. Leasing agreements and certification requirements made it even harder to look elsewhere.

The result? Many airlines are still paying OEM prices even when qualified, approved alternatives exist. When margins were healthier and fuel was cheaper, that was an acceptable trade-off. Today, it's harder to justify.

The Stakes of Doing Nothing

The parts shortage problem isn't going away anytime soon. The global production backlog keeps growing, inventory is tight and older fleets need more upkeep. Airlines are absorbing billions in maintenance costs while fighting over scarce supply.

Meanwhile, the commercial MRO market is expanding, which adds more pressure to procurement budgets. Airlines that stick to traditional sourcing models risk paying more and waiting longer, not a great combination.

The silver lining: most airlines already have access to approved alternatives. The missing piece is a clear strategy to find, vet and actually use them at scale.

Five Things That Actually Move the Needle

1. Figure out where you have room to substitute

Not every part offers the same flexibility. Some flight-critical systems have very tight certification requirements. Others have multiple approved suppliers that can deliver the same airworthiness outcomes for less.

Start with a portfolio-wide review of your LRU and C&E spend. Map where substitution is feasible and where the savings potential is highest. It turns procurement from a reactive purchasing function into something genuinely strategic.

2. Build a real alternative supplier pipeline

Plenty of airlines use PMA (Parts Manufacturer Approval) components to plug gaps during shortages. Far fewer have a formal process for evaluating and expanding their use before a shortage hits.

A proper qualification framework covering technical review, regulatory compliance and operational validation lets you bring in PMA parts, Used Serviceable Material (USM) and other certified alternatives confidently. The savings versus new OEM components can be substantial.

The real barrier usually isn't regulation. It's habit and entrenched supplier relationships.

3. Take a hard look at consumables and expendables

These don't get the attention of major components, but they add up. Lubricants, adhesives, sealants, fasteners, cleaning materials: many of these have approved equivalents from multiple manufacturers.

Because most airlines buy them through established catalogs, cheaper approved alternatives often go unnoticed. A focused review here is one of the quickest wins available to procurement teams.

4. Consolidate spend and negotiate from strength

Buying similar products from a dozen different suppliers fragments your spend and weakens your negotiating position. Consolidating into preferred agreements with key suppliers lets you unlock volume rebates, better pricing and simpler supplier management.

Less complexity, better terms, more reliable supply. It's a win on multiple fronts.

5. Connect procurement to predictive maintenance

This one is underutilized and worth paying attention to. Predictive maintenance systems can flag potential issues months in advance, which gives your procurement team time to source parts strategically rather than scrambling when something breaks.

That means fewer emergency buys, less exposure to aircraft-on-ground premium pricing, and a procurement function that actually supports operational continuity instead of just reacting to it.

The Long Game

One-off contract renegotiations are fine, but they only go so far. Building real alternative sourcing capabilities, a strong PMA program, a substitution strategy, preferred supplier agreements, predictive maintenance integration, creates advantages that compound with every maintenance cycle.

As fuel stays volatile and supply chains stay tight, airlines with these capabilities will be better placed to protect their margins. Procurement leaders who act now won't just weather the current pressure better; they'll have built something that keeps paying off for years.
