Gatwick Airport claimed they were busy but not chaotic.
"The airport is operating normally but will be busy today with over 780 flights and 110,000 passengers," said a spokesperson. "We continue to advise passengers to arrive at the airport as soon as check-in opens for their flight. Typically, this is 3 hours for long-haul and 2-2 ½ for short-haul."
