Ryanair said: “Affected passengers will be notified and any passengers travelling across the network on Fri 19 July should check their Ryanair app for the latest updates on their flight. We advise passengers to arrive at the airport 3 hours in advance of their flight to avoid any disruptions.
“We regret any inconvenience caused to passengers by this 3rd party IT issue, which is outside of Ryanair’s control and affect all airlines operating across the network.”
Britain’s biggest train company Govia Thameslink Railway (GTR), the parent company of Southern, Thameslink, Gatwick Express and Great Northern, warned passengers to expect rail disruption too.
The message stated: “We are currently experiencing widespread IT issues across our entire network.
“Our IT teams are actively investigating to determine the root cause of the problem.
“We are unable to access driver diagrams at certain locations, leading to potential short-notice cancellations, particularly on the Thameslink and Great Northern networks.
“Additionally, other key systems, including our real-time customer information platforms, are also affected.
“We will provide additional updates when we can. In the meantime, please regularly check your journey before you travel.”
National Rail Enquiries said that “network wide IT issues” were affecting a “number” of train operators across the whole country.
South Western Railway said none of its ticket machines were working this morning and urged travellers to buy their tickets online or from a member of staff.
