A largely trouble-free day is predicted for Gatwick, Heathrow and Stansted airports but there may be further disruption at other airports after yesterday's glitch with air traffic control.
Flights were cancelled or delayed after problems with a telephone system at the National Air Traffic Service.
The problem was resolved at about 7.30pm yesterday. The disruption is likely to have a knock-on affect at some airports today but London's three main airports say their flights should run relatively smoothly.
