British air passengers are facing delays following a Europe-wide computer problem affecting luggage.
At Heathrow airport, some flights were leaving late, with some passengers facing the possibility of having to fly without their hold luggage.
British Airways was one of the many airlines affected. One passenger, Dan Rivers, took to Twitter to say his BA flight had departed "minus 100 bags".
A BA spokesman said: "We are doing all we can to minimise disruption caused by an IT failure which is affecting the performance of baggage systems at numerous airports.
"We are very sorry if customers have not received their baggage and we will reunite them as quickly as possible."
A spokesman for management at Heathrow said: "We are aware that there is a European issue with the Sita system that manages bags for some airlines.
"We understand that Sita is applying a fix to the problem and we hope that it will be resolved soon. In the meantime airlines that are affected are processing bags manually. The problem is causing some delays but is not currently causing any flight cancellations at Heathrow."
plans worked well and there were no issues with lost baggage or delayed flights."
