Rochford Council has approved a 90-metre terminal extension at London Southend Airport.
This expansion will allow the airport to increase the number of check-in desks, baggage reclaim facilities and security screening channels, as well as make the departure lounge more spacious and provide an increased range of shops.
The extension is designed to help the airport cope with increased passenger numbers of two million per year up to 2020.
London Southend Airport managing director Alastair Welch said he was "very pleased" that the council was behind the plans.
"This is also further evidence of the role the redeveloped airport is playing in supporting the regeneration of the wider economy," he added.
It is hoped that construction work on the extension will begin later this year.
The airport has undergone a number of upgrades recently, with a new air traffic control tower opening in March 2011 and a dedicated airport railway station providing links to central London made operational in July 2011.
