Residents living under Heathrow’s flight paths are being kept awake until after midnight by an increase in late running night flights due to disruption across the aviation sector.
The west London airport apologised to people suffering “greater disturbance” as more aircraft are arriving and departing later than planned.
Heathrow does not have any scheduled departures between 10.50pm and 6am, or scheduled arrivals between 10.55pm and 4.40am, but take-offs and landings occur within those periods when planes are delayed.
On Saturday night three aircraft arrived at Heathrow after midnight.
The latest was a British Airways flight from Kalamata, Greece which touched down at 12.31am, more than two hours behind schedule.
Overflown residents were given little respite, as the first flight scheduled for Sunday morning arrived at 4.33am.
