Gatwick Airport is warning passengers an ongoing issue with some self-service bag drop machines could lead to delays today (27 March).
Passengers flying over the weekend complained of long queues, with some taking to social media to highlight the problem.
The technical issues have now entered a third day.
The airport said a third party, who manufactured the self-service check-in kiosks, experienced a global technical issue over the weekend.
An airport spokesperson said: “Passengers may experience delays today at Gatwick Airport, due to a continuing issue with a small number of self-service bag drop machines.
“The machines are manufactured by a third party, who experienced a global technical issue over the weekend.”
But the spokesperson added: “The majority of the machines have been checked and restarted under a different operating system.”
The airport said it was not expecting any flight delays and travellers should come to the airport as usual.
Elaine MacDonald, who travelled on Sunday, called scenes ‘absolute carnage’.
“If anyone is travelling from Gatwick Airport today, BA bag drop is currently taking about an hour to an hour and a half because of technical issues earlier,” she tweeted.
“Absolute carnage, bag has (hopefully) made my flight by the skin of its teeth.”
On Sunday, Sarah Mo from London told the BBC that ‘hundreds of people’ were getting ‘really stressed about missing their flights’.
Another passenger said queues were ‘out of the door’, adding she had waited for 90 minutes.
