Global maintenance, repair, and overhaul demand reached $136 billion in 2025, up 8 percent from $126 billion the prior year, according to forecast data from Oliver Wyman. Spending is projected to rise to nearly $140 billion in 2026 and to approach $193 billion by the middle of the next decade, nearly double the 2019 level, in what analysts describe as an extended maintenance super cycle.

An aging global fleet drives much of the increase. Older aircraft require more frequent maintenance and more replacement parts, which pushes up demand and prices for both components and labor. The forecast notes that in regions with the oldest fleets, including North America, Western Europe, and Africa, maintenance spending will outpace fleet growth, concentrating the strongest demand in mature markets such as the United States.

The forecast also flags constraints that complicate the growth picture. Technical challenges with certain engine programs and broader supply chain limits, including shortages of raw materials such as composites and titanium, are tying up maintenance schedules and extending turnaround times. The data points to a maintenance market expanding steadily on the back of fleet age and rising utilization, while parts and labor scarcity keep upward pressure on costs across the sector.
