Thousands of British Airways passengers have been forced to fly without their bags.
For several hours the baggage system in Heathrow's Terminal 5 has been out of operation because of an IT problem, according to the airline.
The problem is with the belts. Passengers have been able to check-in bags but they have not been able to process them. It means passengers are flying without luggage.
BA says the problem is now "just about" fixed. A spokesman apologised and said flights were not affected. Similar problems marked the opening of Terminal 5.
