Britain's Gatwick Airport reopened on Friday after a rogue drone saboteur wrought travel chaos for hundreds of thousands of Christmas travellers by playing cat-and-mouse with police snipers and the army.

After the biggest disruption at Gatwick, Britain's second busiest, since a volcanic ash cloud in 2010, Gatwick said its runway was open and that a limited number of aircraft were scheduled for departure and arrival.

"Gatwick's runway is currently available and a limited number of aircraft are scheduled for departure and arrival," the airport said.

"Gatwick continues to advise passengers to check the status of their flight with their airline before travelling to the airport as departures and arrivals will be subject to delays and cancellations."
