(Ap Photo/Joanna Chan) A major air traffic control issue left almost two thousand flights cancelled yesterday in the UK, per data from analytics company Cirium. National Air Traffic Services (NATS) said the technical problem has since been resolved, however further disruption is expected today. It serves 15 UK airports including Heathrow, Newcastle, Manchester, Gatwick and Stansted. NATS boss Martin Rolfe apologised for the issue, saying there’ll be a full investigation into what happened. People have been left sleeping on airport floors, with nearby hotels being booked up immediately after the chaos began to unfold. Airline bosses have called for “urgent reform” over the issue. Wizz Air UK’s boss Yvonne Moynihan pointed out to Sky News it’s the third summer that passengers have been affected by air traffic control problems. Ryanair has called on Rolfe to quit as a result of the chaos, which it said disrupted over 65,000 of its passengers. What are the airports saying? As on the time of writing, the following airports had shared updates on their websites or social media: Aberdeen Airport “A technical issue affecting NATS air traffic control services is causing disruption to some flight departures. As a result, some services operating to and from our airports may experience delays. “We apologise for any inconvenience and advise passengers to check with their airline for the latest flight information before travelling.” Belfast International Airport “Flights are operating to schedule this morning however some delays can be expected as the day goes on. If you are due to travel please check your flight status with your airline.” Bristol Airport “Following yesterday’s nation-wide National Air Traffic Services (NATS) technical issue, flights are mostly back to normal with a small number of delays and cancellations. Customers should check the latest flight information with their airline.” Cardiff Airport “Following technical issues affecting air traffic control services across parts of the UK yesterday, Cardiff Airport is operating as normal today. “NATS has advised that work is continuing to assist airlines and airports with the recovery from yesterday’s disruption, which has created difficulties across the wider aviation network. We encourage passengers to check directly with their airline or travel operator for the latest information on the status of their flight.” Heathrow Airport “Following yesterday’s technical issue affecting NATS air traffic control, Heathrow’s operations are recovering. “Flights are operating today, however some knock-on disruption is expected as airlines reposition aircraft and crew. Passengers are advised to check the latest status of their flight directly with their airline and to only travel to Heathrow if their flight is confirmed as operating today. “We apologise to passengers affected by the disruption. Additional colleagues are available across our terminals to provide support, and we are working closely with NATS and our airline partners to return operations to normal as quickly as possible.” London Luton Airport “Following yesterday’s technical issue affecting NATS air traffic control, London Luton Airport is open and operational today. However, it is likely that there will be a knock-on impact as airlines work hard to recover their schedules. “We advise passengers to check the status of their flight directly with their airline before travelling to the airport. We appreciate how frustrating this situation is and apologise to those affected. We have extra colleagues on hand to support across our terminal.” Manchester Airport “Following yesterday’s NATS air traffic control issue, the airport is operating as normal. Those travelling today should continue with their journey plans and check with their airline for the latest information on their flight, as usual.” Southampton Airport “Following yesterday’s technical issue affecting NATS air traffic control, our airports’ operations are recovering. “Flights continued to operate yesterday and today, but we are expecting ongoing disruption as aircraft and crew reposition. We advise passengers to check with their airline for the latest flight information and to only travel if they have a confirmed flight operating today. “We apologise for the inconvenience caused by this NATs related technical issue and will continue to provide support to our passengers.” London Stansted Airport “Following yesterday’s NATS air traffic control issue, the airport is operating as normal. Those travelling today should continue with their journey plans and check with their airline for the latest information on their flight, as usual.” What are your rights? Heathrow has warned passengers of potential delays on Wednesday as a result of the technical glitch, with Bristol Airport also warning to expect more disruption. Rory Boland, editor of Which? Travel, said passengers have the right to food or a hotel stay depending on the length of their delay – but he urged travellers to “keep the receipts” as you’ll need to claim the costs back from your airline. Anyone due to travel today should check the advice from their airport, tour operator or airline for the most up-to-date advice. ABTA, a trade association for tour operators and travel agents, said it will be supporting passengers who have booked with them to “help make alternative arrangements”. Per ABTA’s advice page, if your flight is cancelled and you’re departing from the UK, your airline must offer you the choice of a replacement flight at the earliest opportunity or a refund. If the flight delay exceeds five hours, your airline must offer you the choice of taking a refund of the flight cost. Luke Petherbridge, director of public affairs at ABTA, said: “While the immediate priority is supporting customers, as this isn’t the first Nats outage to cause widespread disruption, the industry and the public will want answers as to what has gone wrong, what lessons are being learned, and how the system will be made more resilient to avoid this happening again.” Related...
