Heathrow Airport in London, UK has resolved the issue with its baggage-handling system, which suffered a failure at Terminals 3 and 5.

The failure prevented bags from being checked in and forced some of the passengers to fly without luggage, reported Reuters.

Passengers were advised to pack their essential items in their hand luggage.

Heathrow Airport said in a tweet: “We recommend that passengers who have already departed on flights this morning without their baggage contact their airline for further updates.”

Passengers travelling with British Airways, Iberia, and American Airlines from Terminal 3 and Terminal 5 were affected by the baggage problem, reported the BBC.

Heathrow has asked its passengers, who were forced to travel without their luggage, to contact their respective airlines to find out when it would be returned to them.
