Its half-year results revealed the airport has handled 26.5 million passengers in the six months ending September 30, 2018.
This was only an increase of 100,000 on the previous year, and Gatwick chief executive Stewart Wingate said the limited growth, which equated to 0.5%, was becuase airlines had been building towards full utilisation of slots made available and acquired when Monarch ceased trading.
This also resulted in fewer flights through the airport in the period compared to last year.
However, there was a 21.3% increase in long haul passengers meaning one in six using the airport are now travelling to far-flung destinations
