Stansted Airport enjoyed its busiest December in four years after nearly 1.32 million passengers passed through the airport.
It was the fourth consecutive month of growth for the airport and an increase of 7.7% over the same month last year.
The overall number of passengers using Stansted in the past 12 months also increased by 2.2% to just over 17.84 million, the first full year of growth since 2007.
Managing director Andrew Harrison said the future was looking bright.
Mr Harrison said the airport was set to serve more than 30 million passengers a year by 2024 and was on track to reach its current planning limit of 35 million passengers by 2030.
Stansted is now turning its attention to developing long-haul services and is looking to attract airlines to put on flights to the Middle East, North American and Asia.
