Severe storms in late June caused 900 flight delays across two UK airspace sectors, with some delays reaching 11 hours and dozens of cancellations. Experts warn that climate change will intensify storms and increase similar disruptions in busy airspace, while rising fuel costs from longer routes and extra reserves are expected to push ticket prices higher.

Key Facts

Severe storms in late June caused 900 flight delays across two UK airspace sectors, with some delays reaching 11 hours.
Clear-air turbulence over the North Atlantic has increased by 55% since 1979, according to Professor Paul Williams of the University of Reading.
269 airports worldwide are currently at risk of flooding, with Amsterdam Schiphol, London City, and Newark Liberty among the most exposed.
Airlines may be forced to load extra reserve fuel as weather-related delays become more common, increasing operating costs.

Storm Disruptions

Severe storms in late June caused 900 flight delays across two UK airspace sectors, with some delays reaching 11 hours and dozens of cancellations. Experts say climate change will make storms more intense and similar disruptions more frequent in busy airspace. Storms narrow usable airspace, forcing aircraft to change routes and divert to other airports. This extends flight times and increases fuel consumption.

Fuel Costs and Fares

Airlines may be forced to load extra reserve fuel as weather-related delays become more common. Fuel is one of the industry's largest costs, so this is expected to be reflected in ticket prices. Clear-air turbulence over the North Atlantic has increased by 55% since 1979, according to Professor Paul Williams of the University of Reading. Severe turbulence on busy flight routes could become two to three times more frequent in the future.

Airport Flood Risk

269 airports worldwide are currently at risk of flooding. Amsterdam Schiphol, London City, and Newark Liberty are among the airports facing the highest risk. The aviation industry will try to adapt to new conditions through technological and infrastructure investments. For passengers, the result may be more delays, cancellations, and higher travel costs.
