Heathrow Flight Disruption: Latest NATS Update, Cancellations and Passenger Advice

Last verified: September 9, 2026. A technical problem in the United Kingdom’s air traffic control system caused major disruption at Heathrow and airports across the country on September 8. Although the technical issue was resolved, airlines and airports warned that delays and cancellations could continue while aircraft and crews returned to their planned positions.

If you are travelling through Heathrow, do not rely only on the time printed on your original booking. Check the latest status directly with your airline before leaving for the airport.

What happened at Heathrow?

Heathrow said that arrivals were suspended for the remainder of September 8 following an earlier technical issue affecting NATS, the UK’s air traffic services provider. Departures later resumed, but the airport warned passengers to expect continuing disruption and to confirm flight information with their airline.

The disruption was not limited to Heathrow. Airports and airlines across the UK experienced delays, diversions and cancellations. An Associated Press report said more than 1,000 flights were cancelled during the wider incident, leaving large numbers of passengers needing new travel arrangements.

What passengers should do now

Check the airline’s app or website first. The airline controls your booking and will normally provide the most relevant cancellation, gate and rebooking information.
Check Heathrow’s official travel update. Airport-wide information can change as the backlog is cleared.
Do not travel to the terminal solely on the original schedule. Follow the airline’s instruction, especially if your flight is cancelled or moved to another day.
Keep screenshots and receipts. Save the cancellation notice, revised itinerary and reasonable receipts for food, transport or accommodation.
Check every connecting flight separately. A long-haul flight may operate even when a domestic or European connection is cancelled.

How to track a Heathrow flight

Use the flight number rather than searching only by destination. You can check:

your airline’s official app, website or notification service;
Heathrow’s live arrivals and departures pages;
the departure airport if your aircraft is arriving from another location; and
a reputable flight tracker for the aircraft’s latest movement.

A third-party tracker is useful for context, but it does not replace an airline’s formal cancellation or rebooking notice.

Refund, rebooking, food and hotel rights

The UK Civil Aviation Authority says passengers on many flights departing from the UK—and certain flights arriving in the UK—have legal protections when a flight is cancelled.

For a covered cancellation, the airline should normally offer a choice between:

a refund for the unused part of the ticket; or
an alternative flight to the destination.

The airline may also have to provide reasonable care while you wait, including food and drink, communication, accommodation when an overnight stay is necessary, and transport between the airport and accommodation. If airline staff cannot arrange this during widespread disruption, keep receipts for reasonable expenses and follow the airline’s claims procedure.

Cash compensation is a separate question. Eligibility depends on the route, notice given and the cause of cancellation. Air traffic control failures may be outside an airline’s control, so passengers should not assume that every cancelled flight qualifies for fixed compensation. Refund, rerouting and care rights can still apply even when compensation is not payable.

Visa and immigration checks after a cancellation

A flight cancellation does not automatically extend a visa, entry clearance, transit permission or permitted stay. Travellers should check the rules that apply to their circumstances.

If rerouting passes through a different country, check whether an airport transit visa is required.
If your permission to stay is close to expiring, keep evidence of the disruption and obtain guidance from the responsible immigration authority.
If you miss a visa appointment, contact the embassy, consulate or application centre using its official channel.
Check that your passport and any electronic travel authorisation will remain valid for the revised journey.

What if separate tickets are involved?

Passengers with separate bookings may have less protection for a missed onward flight than passengers travelling on one through-ticket. Contact the onward airline immediately. Also check travel insurance and the payment card used for booking, as either may provide additional protection.

Quick Heathrow disruption checklist

Confirm the flight directly with the airline.
Check the terminal and new departure time.
Review connecting-flight and transit-visa requirements.
Choose refund or rerouting only after considering the whole itinerary.
Keep receipts and written notifications.
Avoid unofficial agents asking for payment to “unlock” a refund or replacement flight.
