Due to drones flying over Gatwick Airport in the airspace, nothing has gone into or out of Gatwick Airport for 15 hours since about 9pm last night UK time.
At noon UK time today Gatwick is still closed.
All flights to and from are being cancelled or diverted to other London or UK or European airports with some flights being diverted as far as southwest France.
This not only affects Gatwick flights but flights all around the southern UK as those airports are coping with all the additional flights and passengers.
Strong advice is if you are planning on flying into, from, or within the UK before Christmas to carefully check with your airline.
