Ryanair penalised for persistent delays as Eindhoven Airport revokes flight slots

In a rare disciplinary move within European aviation, Eindhoven Airport has withdrawn two takeoff and landing slots from Ryanair after the airline repeatedly operated flights deliberately late during the summer season. The decision, taken by the Dutch slot coordinator ACNL, marks one of the rare instances where an airport has enforced slot losses solely based on structural delays.

According to ACNL, Ryanair consistently missed its allocated times on two routes despite warnings issued in mid-June. When the pattern persisted, the coordinator intervened. Aviation expert Joris Melkert of Delft University of Technology calls the measure “unique” — and a necessary wake-up call.

“The sanction is a clear warning,” Melkert said. “It sends a strong message to Ryanair, and that’s a good thing.”

Melkert explains that Ryanair’s aggressive cost-cutting model, designed to keep aircraft in the air as much as possible, leaves almost no margin during quick turnarounds. As delays accumulate across the day, flights can end up running nearly an hour behind schedule by evening.

Slots — fixed windows during which airlines can land or depart — are crucial at capacity-constrained airports. Persistent slot misuse can disrupt the tightly coordinated daily schedule, creating knock-on delays for other airlines and passengers. Under European slot rules, carriers risk losing historical rights if they fail to operate reliably.

The expert says the Eindhoven move could have wider implications across Ryanair’s network:

“Other coordinators will be watching this very closely. It could very well be that something really needs to be done at Ryanair now.”

For low-cost carriers that rely on rapid turnarounds and tight scheduling, the Eindhoven precedent underscores a growing willingness among airports to enforce discipline — and protect operational reliability — when chronic delays become part of an airline’s routine operations.

In response to ACNL’s decision, Ryanair sent the following statement:

“We have appealed this unprecedented, irrational and disproportionate decision by ACNL to the European Commission and the Dutch courts, where we expect it will be overturned. ACNL are penalising airlines for ATC delays that push flights just 15 minutes over their scheduled arrival time, which is completely out of whack with the vast majority of European airports, where the threshold is much higher and more reasonable. Ryanair has long campaigned for ATC reform, but EU Commission President – Ursula von “Derlayed-Again” – has failed to take action.”
