An IT failure at Gatwick Airport that has caused digital displays to stop working has led staff to write flight information on whiteboards.

Footage filmed today (August 20) at the Sussex airport shows irate passengers huddled around the whiteboard in the South Terminal as staff update information.

The filmer writes: "This is their plan B. It's a mess. Walkie-talkies, a whiteboard and loud voices.

"And a singular flight announcement over PA system... How many people will miss their flights I wonder."

Gatwick Airport tweeted: "Due to an ongoing issue with Vodafone - an IT provider for the airport - our flight information screens are not displaying correctly.

"Please use the temporary flight boards in the departure lounges or listen for airline flight announcements."

Due to an IT issue there are no working boards at London Gatwick. This is their plan B. It's a mess. Walkie talkies, a white board and loud voices. And a singular flight announcement over PA system... How many people will miss their flights I wonder.
