Some flights were delayed up to three hours – and the lag may affect other flight timings
London: Heathrow Airport is warning passengers to check their flight status after problems with runway lighting caused disruption.
Europe’s largest airport said on Wednesday that the problem had been resolved by 6.05am GMT (12.05 a.m. EST) and that both runways are now open and operational. But travellers should check, as delays are expected throughout the morning.
Some flights were delayed up to three hours, and the problem left some London-bound travellers stranded on US tarmac.
Heathrow said in a statement that its engineering teams are investigating.
