Ryanair calls for NATS chief to quit as NI airports warn of delays

Ryanair has renewed its demand for the head of the UK’s air traffic services provider NATS to step down after a Monday morning technical problem at NATS’ Prestwick centre triggered flight restrictions and a new wave of delays and cancellations affecting Northern Ireland airports.

What happened at NATS’ Prestwick centre

Published coverage indicates NATS introduced air traffic regulations early Monday, September 21, 2026, after a technical issue emerged at its Prestwick facility in Scotland, a centre that manages significant volumes of traffic in the north of the UK. NATS later stated the fault had been fixed, while warning that removing restrictions safely would take time and that knock-on disruption could continue.

NATS described the problem as a connectivity issue within part of its systems network and said it was specific to the Scotland operation, rather than a repeat of the separate nationwide disruption earlier this month. Even when the underlying issue is resolved quickly, airport departure sequences, aircraft positioning, and crew duty-time limits can keep schedules unstable for the rest of the day, particularly on tightly timed short-haul networks.

The new incident landed just days after NATS published preliminary findings on the September 8, 2026 disruption, which caused widespread travel chaos and a long recovery tail as aircraft and crews fell out of place across multiple bases.

Northern Ireland airports issue passenger warnings

Airports in Northern Ireland posted advisories urging travellers to monitor flight status closely before setting off to terminals, reflecting the fast-changing pattern typical of airspace-related disruption. The most immediate effects were seen on routes connecting Northern Ireland with Scotland, northern England, and London-area airports that feed onward connections.

By late Monday, published reporting citing flight tracking and analytics pointed to Belfast International Airport and George Best Belfast City Airport as among the locations experiencing the heaviest disruption, alongside Manchester and Edinburgh. Disruption patterns can vary hour by hour because air traffic flow measures may affect inbound aircraft rotations differently than outbound departures.

While airspace restrictions were concentrated in the northern parts of the UK, travelers elsewhere were not necessarily insulated. When aircraft miss earlier sectors, later services can be delayed or cancelled due to aircraft availability, crew hours, and airport stand constraints, which can spill into evening schedules and the following morning’s first wave.

Ryanair escalates pressure on NATS leadership

Ryanair’s latest statement called for NATS chief executive Martin Rolfe to resign, framing the Prestwick issue as another failure arriving less than two weeks after the September 8 outage. The airline also urged UK Transport Secretary Heidi Alexander to remove Rolfe if he does not step down.

In its published account of Monday’s disruption, Ryanair said more than 140 of its flights had been delayed and estimated that more than 25,000 of its passengers would be affected, with some delays stretching to multiple hours. The carrier linked its criticism to what it described as inadequate operational resilience and insufficiently effective backup arrangements.

The renewed leadership dispute arrives amid broader airline frustration about repeated UK air traffic-related disruption in recent years, including the August 2023 national outage that became a reference point in ongoing debates over investment, operational readiness, and accountability for passenger impacts.

What passenger rights look like during ATC failures

The UK Civil Aviation Authority issued updated guidance on Monday’s Prestwick disruption, reminding airlines of their obligations to look after passengers when flights are delayed or cancelled. That duty of care generally covers essentials such as meals or refreshments appropriate to waiting time, and where necessary, hotel accommodation and transport between the airport and lodging, depending on the circumstances and the length of the disruption.

At the same time, the regulator indicated that disruption directly caused by the NATS Prestwick technical issue is likely to be treated as “extraordinary circumstances” under passenger rights rules. In practical terms, that means many travellers may not qualify for cash compensation tied to delay length if the disruption is attributed to the air traffic control incident, even though airlines still need to provide assistance and rerouting or refunds where applicable.

For passengers, the immediate decision often becomes tactical rather than legal: whether to wait for re-accommodation on the next available flight, accept a rebooking that may be on a different route or time, or take a refund and make alternative plans. The right choice can differ sharply depending on whether the traveller is flying point-to-point or trying to protect an onward connection.

What to watch next for UK and Ireland flight schedules

With two separate NATS technical incidents in September, airlines and airports are likely to face continued scrutiny over operational recovery and the robustness of contingency planning. Even a short outage can force flight cancellations if runway slots, night restrictions, or crew duty-time rules limit how far schedules can be extended into the evening.

Travellers flying to or from Northern Ireland in the coming days may see residual impacts, particularly on aircraft rotations that begin the day at outstations or rely on tight turnarounds. Flights that appear on time earlier in the day can still shift if inbound aircraft or crews arrive late due to knock-on restrictions.

NATS has said Monday’s connectivity issue was unrelated to the September 8 software-related event, but the back-to-back timing keeps attention on the UK’s ability to maintain stable airspace operations during high-demand periods. For passengers, the most reliable short-term indicator remains airline-specific flight status updates and airport departure boards as schedules are rebuilt.
