The Most At-Risk Flights in Europe for the Week of August 17, 2026
The week starting August 17, 2026, sees certain European routes and airports particularly subject to risks of delays and disruptions. Analyzing the risk scores related to airports and connections reveals some important trends every traveler should know to better plan their journey.
The 10 Most At-Risk European Airports
The ranking is based on an average risk score due to several factors such as adverse weather conditions, air traffic congestion, and possible strikes by ground staff or air traffic control (ATC).
Although most of the highest-risk airports currently are in North America, in Europe there are airports with significant criticalities, especially regarding traffic and seasonal conditions:
- Rome Fiumicino Airport (FCO) - summer congestion and possible strikes by ATC staff
- London Heathrow Airport (LHR) - very high traffic and repercussions on extended waiting times
These hubs often experience delays due to infrastructure overload during the summer peak. Unstable summer weather conditions, such as sudden showers and thunderstorms, further increase the risk of delays, typically modest but worth monitoring.
The Most Critical Routes to Monitor
Among the routes with the highest risk for the same week, elevated values are found especially on intercontinental and secondary air routes.
The connection JFK (New York) -> YQB (Quebec City) and other transatlantic flights face significant pressure due to high summer demand and the complexity of ATC coordination between Europe and America.
Factors Affecting Flight Risks
Weather: The variability of summer climate, with sudden thunderstorms in Europe, can cause operational restrictions at airports like FCO and LHR.
Air traffic control: Limitations in managing air traffic, especially during local strikes or staff reductions, heavily impact waiting times.
Congestion and infrastructure: Major airports suffer runway and gate saturation, particularly in the summer period.
Practical Tips for Travelers
