The airport updates on the situation at 11 am Friday 19 July.
A spokesperson said:
‘The global IT problems are continuing to affect some of our airlines this morning. That means some processes like check-in and boarding are being carried out manually and are taking longer than usual for those airlines.
‘The majority of flights operating from the airport are unaffected, but the terminal is slightly busier than usual as a result of the situation.
‘Passengers should continue to check the status of their flights with their airlines before they leave for the airport and should follow their airlines’ advice about the best time to arrive at the airport. We also advise checking up-to-date travel advice as some train services have also been affected by the issues.
”Some of our retailers have also been affected meaning they have been unable to process card payments.
Our customer service colleagues are on hand to assist in the terminal. We thank all our passengers for their patience and understanding.’
Sky News was taken off air by the IT failure, as were thousands of businesses around the world.
