British Airways has cancelled all short-haul flights from Heathrow Airport until midday on Saturday.
BA apologised for the cancellations, caused by ongoing technical issues.
All long-haul services at Heathrow and all flights at Gatwick and London City Airport are due to operate as planned, but customers may experience some delays, the company warned.
Anyone due to travel later was advised to check their flight status before travelling to the airport.
