1,669 flights delayed or canceled across Heathrow, Schiphol, and Athens hubs

Disruption overview

A weekend wave of delays and cancellations hit 1,669 flights on 24 May 2026, with Athens International Airport, Amsterdam Schiphol Airport, and London Heathrow Airport among the busiest centers of disruption. Air France, British Airways, KLM, and Aegean Airlines were especially visible in the affected schedules as weather, crowded airspace, and staffing shortages strained some of Europe's most important connection points.

For passengers, that meant long lines, missed connections, and some unplanned overnight stays. Because the causes appear to be mixed, whether compensation applies depends on what disrupted your specific flight and whether it was within the airline's control, but care, rerouting, or a refund may still apply in some cases. If your trip was affected, keep your receipts and use AirHelp's free flight checker to understand what may apply.

Disruption details

Major European hubs were hit by fresh disruption on 24 May 2026, with 1,669 flights delayed or canceled across Athens International Airport, Amsterdam Schiphol Airport, London Heathrow Airport, and other airports across the region. For passengers, that meant long lines, missed onward connections, and, for some, an unexpected overnight stay.

Flight-tracking dashboards showed:

• 1,618 delayed departures

• 51 canceled departures

• Heavy pressure at Athens International Airport, Amsterdam Schiphol Airport, and London Heathrow Airport

Air France, British Airways, KLM, and Aegean Airlines were among the airlines appearing most often in the disruption figures. That's a reminder of how exposed large network carriers can be when they depend on tightly timed arrival and departure banks at hubs such as Paris, London, Amsterdam, and Athens.

Once the first wave of flights starts running late, the rest of the day can unravel quickly. Aircraft miss their next assignments, crews fall out of position, and airlines can run out of room to recover. That's why early delays often turn into later cancellations or thinner schedules, with knock-on effects reaching secondary airports as well.

There wasn't one single cause behind every affected flight. Weather was part of the picture, but so were congested European air corridors and staffing shortfalls in ground handling, security screening, and air-traffic-control centers. Together, those pressures reduced runway capacity, triggered ground-delay programs, and left little spare time in the system once morning operations slipped behind.

With passenger demand already running ahead of the same period in 2025, the network had very little slack. That made even modest disruption harder to absorb, especially at major connecting airports where one late feeder flight can jeopardize an entire itinerary.

For travelers passing through the biggest hubs, the consequences were often bigger than the first delay on the board. Remaining seats on later long-haul flights were limited once connections were missed, leaving some passengers facing long waits, rushed rebookings, or an involuntary night away from home.

Airlines including Air France, KLM, British Airways, and Aegean Airlines advised passengers to keep their boarding passes and receipts. If your journey was affected, those documents can help if you need to ask the airline for reimbursement or other support after the disruption.

With the summer peak still ahead, this latest weekend of disruption is a warning sign for anyone traveling through Europe's largest hubs. The network remains vulnerable when weather issues, staffing gaps, and busy airspace hit at the same time. If you're flying through a major connection point, building in extra time and checking your flight status regularly could make a stressful day a little easier to manage.

Because this disruption appears to involve a mix of weather and wider operational strain, whether compensation applies will depend on what caused your specific delay or cancellation and whether it was within the airline's control. In some cases, EC 261 or the UK equivalent may apply. Even when compensation doesn't, you may still have a right to care, rerouting, or a refund depending on what happened. If your flight was affected, keep your travel documents and receipts, and you can use AirHelp's free flight checker to see what rights may apply.
