08:06 AM EDT, 10/13/2025 (MT Newswires) -- The airline industry was hit by over $11 billion of extra costs in 2025 due to supply chain challenges, the International Air Transport Association said Monday.

Citing a study produced with consultant Oliver Wyman, the industry group said that the additional expenses were driven mainly by excess fuel costs, additional maintenance costs, increased engine leasing costs, and surplus inventory holding costs.

Supply chain challenges delayed the production of new aircraft and parts, as well as hindered the ability of airlines to deploy sufficient aircraft to meet growing passenger demand, which rose 10.4% in 2024, according to the study.
