An issue with the air traffic control system has resulted in flights being suspended at Britain's second busiest airport.
Aashna Shroff, personal finance expert at money.co.uk, comments:
"The delays at Gatwick are due to a problem with the air traffic control system and no fault of the airlines, so you're unlikely to be compensated by your airline if your flight is delayed or cancelled.
"But it's still worth checking with your airline what its policy is on delays and cancellations.
"It's likely that delays caused by extraordinary circumstances, will not be covered by your airline.
"Extraordinary circumstances are typically events which are outside of the airline's control, such as extreme weather and bird strikes.
"But delays or cancelled flights might be covered by your travel insurance, so check your policy documents."
