Hundreds of passengers were left in the dark at Gatwick airport, London on Monday morning after departure screens which display live information for flights went blank.
The airport was forced to draft in whiteboards which staff are having to relentlessly update with the latest information.
Hundreds of travellers surrounding the back-up boards desperate to find out where their gates are.
London Gatwick tweeted: “We are sorry, but due to an IT issue our flight information is not displaying correctly.
“Please use the temporary flight boards in the departure lounges or listen for airline flight announcements.
“We are expecting to resolve the issue soon and apologise for the inconvenience.”
