Airline ImPax Report

Global Disruptions Overview

This month’s report analyses the disruption data of 246 airlines totalling 715,872 disrupted flights, across 2,742,051 planned flights, globally.

June marked a challenging start to the peak summer travel season as geopolitical tensions, adverse weather, ATC disruption and constrained airspace combined to drive operational pressure across every major region. While flight volumes remained resilient, disruption intensified as airlines entered their busiest period with limited operational slack. Tier 1 carriers bore the brunt of this pressure, accounting for 60% of global flight volumes but nearly 80% of all disrupted flights. As a result, almost 24 million passengers experienced major delays or cancellations during the month, highlighting how disruption continues to concentrate around the world's largest and most interconnected airline networks.

Asia Pacific

June is typically a plateau month as airlines fine-tune schedules ahead of the July and August travel peak. This year, however, that seasonal slowdown was more pronounced as carriers exercised greater capacity discipline amid elevated fuel costs, geopolitical uncertainty and operational pressure - not weakening demand. Flight volumes remained 12% below June 2025, underlining that recovery is still underway. At the same time, Typhoon Jangmi disrupted thousands of flights across Northeast Asia, exposing the limited operational resilience of the region's highly interconnected hub networks and driving disruption higher despite fewer flights operating.

Europe

Flight volumes increased by almost 5% in June as Europe entered the peak summer travel season, but operational performance deteriorated sharply. A combination of severe thunderstorms, record-breaking heat, constrained ATC capacity and industrial action placed Europe's busiest airspace under sustained pressure. Major hub airports, including Heathrow, Paris CDG, Amsterdam Schiphol and Frankfurt, became focal points for network-wide disruption as delays quickly propagated across the continent. The number of passengers experiencing major delays and cancellations nearly doubled compared with May, affecting almost 4 million more travellers and highlighting the fragile resilience of Europe's highly interconnected aviation network.

North America

Flight volumes remained broadly stable compared with May as North America entered the peak summer travel season, but the nature of disruption became significantly more severe. Repeated thunderstorms triggered FAA ground stops and flow restrictions across major U.S. hubs, exposing the vulnerability of highly interconnected airline networks. The largest carriers were disproportionately affected, with disruption cascading through their extensive hub operations and driving sharp increases in longer delays and cancellations. As a result, almost 4 million more passengers experienced major delays or cancellations than in May, highlighting how quickly local weather events can escalate into network-wide disruption.

Middle East and Africa

Despite recent geopolitical disruption, the Middle East and Africa continued its recovery in June as airlines cautiously restored capacity while maintaining operational resilience. Flight volumes increased month-on-month as Gulf carriers progressively rebuilt schedules, despite ongoing airspace restrictions, longer routings and elevated fuel costs. Unlike many other regions, airlines largely contained the operational impact of this additional flying, demonstrating an ability to mitigate disruption while adapting to a more complex operating environment. Although traffic remained below June 2025 levels, the region showed clear signs of recovery, balancing network growth with disciplined operational execution.

Latin America

Flight volumes remained broadly unchanged in June, yet operational disruption intensified across Latin America. Technical failures affecting Sao Paulo's air traffic management system, operational issues in Bogota and infrastructure disruption at Lima combined with seasonal winter weather to expose the region's dependence on a handful of critical hub airports. Medium and major delays, along with cancellations, increased by around 25% compared with May, impacting an additional 400,000 passengers. The month demonstrated how relatively minor operational failures at key gateways can quickly cascade through South America's highly interconnected airline networks.
