Heathrow airport has warned that more flights could be cancelled this summer.
The airport noted that the problem was particularly bad during Easter and the Platinum Jubilee and school half-term holiday.
The government and the aviation regulator wrote to carriers last month telling them to ensure their summer timetables were “deliverable”.
Heathrow has, however, apologised to passengers affected by “long queue times, delays for passengers with reduced mobility, bags not travelling with passengers or arriving late”, at times in recent weeks.
Heathrow Chief Executive, John Holland-Kaye said, “We have already seen times recently when demand exceeds the capacity of the airport, airlines and ground handlers.”
He promised that the airport would review the schedule changes that airlines have submitted in response to the government’s requirement to minimise disruption for passengers this summer. “We will ask them to take further action if necessary,” Holland-Kaye assured travellers.
According to the chief executive, “We want everyone who is travelling through Heathrow to be confident that they will have a safe and reliable journey.”
