Belfast International Airport is using whiteboards to provide customers with information, so severely impacted has it been by the global IT outage.
Affected passenger, Martin McElroy, who took the photograph at the international airport, told Sky News, it was like “the dark ages, but to be fair, they’re making it work, which you have to give them credit for”.
Friday’s crash is also affecting airports and banks across the world, as well as broadcasters, including Sky News, which was not able to go on air on Friday morning.

In its most recent post on the social media platform X (formerly Twitter), a spokesperson said: “The Airport continues to remain operational with passengers being processed as normal.
“The airport is part of a global aviation network that is still experiencing disruption so delays and cancellations can be expected. Please check with your airline for the latest updates.
Earlier on Friday morning, an airport spokesperson told The Irish News a “global IT system outage” was impacting the airport and many other businesses.
They added: “However, flights remain operational. Out IT teams are working hard to resolve the issue but there are longer wait times than usual at the airport and we thank passengers for their patience while the issue is resolved.”
Ryanair, which flies out from Belfast International, advised passengers it was “currently experiencing disruption across the network due to a global third party IT outage which is out of our control”.

The company said: “We advise all passengers to arrive at the airport at least 3 hours before their scheduled departure time.
“If you’re due to travel today and have not already checked-in for your flight, you can do so at the airport. We sincerely apologise for any inconvenience caused as a result of this global third party IT outage.”
