Boeing's full 2026 to 2045 Services Market Outlook puts cumulative spending on maintenance, repair, overhaul, and modifications in North America at $270 billion over the next two decades. The figure appears in the report's regional forecast table, which breaks the commercial aviation services market into four segments for each world region.

Across all regions, Boeing values the maintenance, repair, overhaul, and modifications segment at $1,395 billion for the 20-year period. The report charts annual spending in the segment rising from about $117 billion in 2025 to $215 billion in 2045, a growth rate of 3.2 percent per year. Boeing links that demand to aircraft staying in service longer, elevated heavy maintenance requirements, and continued pressure on shop throughput.

North America accounts for $995 billion of the $4.9 trillion global services market, with projected growth of 2.5 percent per year. Within the region, parts and distribution services make up the largest share at $380 billion, followed by information services at $305 billion, maintenance and modifications at $270 billion, and training and pilot services at $40 billion. Boeing projects North American airline fleet growth of 1.2 percent per year through 2045, the slowest of any region in the table.

The outlook also points to used serviceable material as a growing source of parts. Boeing reports that for some MRO shops, these parts cover as much as 30 percent of total part demand, and it expects teardown activity to increase later in the forecast period. The report notes that in North America and Europe, on-shore maintenance often favors line work, quick-turn events, and strategically important repairs close to fleet bases.
