“The methodology of the Airline ImPax Report is sound and the data comprehensive. Delays are organised using logical segmentation, which humanises the scope of the disruption data, making it highly useful and actionable for the aviation industry.”
Henry Harteveldt, President, Atmosphere Research GroupThis month's report analyses the disruption data of 249 airlines totalling 529,952 disrupted flights, across 2,734,433 planned flights, globally.
May 2026 saw continued operational challenges across the global aviation sector as airlines prepared for the peak summer travel season. Disruption was driven by a combination of elevated fuel costs, labour actions in Europe, air traffic control constraints, adverse weather, and airport operational issues, contributing to increased delays and cancellations across several regions. While global flight volumes continued to recover, overall traffic remained approximately 10% below May 2025 levels. North America experienced relatively stable operations despite isolated weather and airport-related disruptions, while the APAC region benefited from continued demand growth and fewer large-scale operational events.
