Gatwick says its runway is currently available - and a limited number of planes are scheduled for departure and arrival.
A drone which has forced the airport to shut down since Wednesday night hasn't been seen since late yesterday evening. The travel plans of more than 120-thousand people have been affected by the chaos.
Ryanair says that its flights through Gatwick today will instead operate via Stansted.
Aer Lingus has also confirmed it will increase capacity on flights to Heathrow and other London airports.
The operator of the drone could face up to 5 years in jail when they're found.
