The UK’s flagship airline insists a full flight schedule will proceed today after a weekend of flight cancellations which began on Saturday morning.
A global IT failure caused the grounding of British Airways (BA) long-haul and short-haul flights, affecting 75,000 passengers.
A BA spokesperson told Express.co.uk: “Our IT systems are now back up and running and we will be operating a full flight schedule at Heathrow and Gatwick on Tuesday May 30.
“We are extremely sorry for the frustration and inconvenience customers experienced over the Bank Holiday weekend and thank them for their patience and understanding.
“We are continuing to work to get delayed bags to customers as quickly as possible and information on how to track a bag can be found on ba.com.”
There are still a “significant number” of customers without luggage after many were forced to fly without bags to their destinations.
BA said: “We are continuing to make good progress in reuniting bags with customers around the world who were affected by the major IT systems failure on Saturday.
“Although we have already flown many bags to the correct airport, there is still some work to do and we know there are still significant numbers of customers who are yet to receive their luggage.”
The airline has ensured customers it will pay all relevant compensation for the delays and cancellations.
Some reports suggest the total bill could surpass £100 million.
Alex Cruz, chief executive of BA, told Sky News: “On Saturday morning at around 9.30 there was indeed a power surge that had a catastrophic effect over some communications hardware which eventually affected all the messaging across our systems.
“We will have completed an exhaustive investigation on exactly the reasons of why this happened. We will, of course, share those conclusions once we have actually finished them.
“We have no evidence whatsoever that there was any cyber attack of any sort.”
Mr Cruz has disregarded calls for him to quit his post in the wake of the IT shutdown.
He has insisted his “outsourcing” of jobs from Britain to India had nothing to do with the airline’s computer system collapse.
Scenes at London’s airports at the weekend saw hundreds of people forced to sleep on yoga mats spread on the floor.
Shops ran out of food due to the number of travellers stranded at meal times.
Many of those who managed to fly arrived at their destination to find luggage missing, and domestic customers clogged up the rail network as they left to catch trains to their destination.
