The airport has said that a number of its systems were affected by the outage this morning (May 11), including check-in, baggage and security.
The issue was resolved by 6am, but passengers have reported long queues hours later.
Posting to X, one passenger said that there were queues outside the airport to get into the terminal.
Stansted Airport right now. IT system issue, the airport says . Some people are queuing outside just to get inside the airport terminal. Some have given up and gone home as they have missed their flights.
