London's Stansted Airport hit by IT problems, delaying flights

LONDON (Reuters) - London's Stansted Airport was hit by IT problems on Sunday that left hundreds of passengers stuck in long queues outside and inside the terminal building and caused delays to flights.

The technical problems, which affected check-in, baggage and security operations, were later resolved, but flights continued to run behind schedule, the airport said in a statement.

Images posted on social media showed people queuing outside the airport. A reporter for television channel ITV, Anne Alexander, said on the X platform that she had missed her flight along with other travellers.

Stansted is the capital's third-biggest airport by passenger numbers.

London's Heathrow Airport, the busiest in Europe, shut down for almost a day in March due to a fire at an electricity substation. On Friday, Manchester Airport in northwest England was hit by a power supply problem which caused delays to arriving passengers at immigration control.
