A Heathrow Airport spokeswoman said "it will take several days" for all of the passengers affected by a computer glitch to receive their luggage.
We experienced intermittent issues with the T5 baggage system between June 26 and 29 which caused some bags to be processed manually. Passengers can now check in bags as normal.
Manual processing led to some bags not making flights in time. While passengers are receiving bags all the time, it will take several days to reunite all passengers with their bags.
We are very sorry for the disruption passengers have experienced and we are working round the clock with airlines to reunite passengers with their bags as quickly as possible.
