The Docklands flight base saw a total of 4,319,521 travellers pass through the departure gates last year compared to 3.6million in 2014.
The 18.38% increase signalled the airport’s fifth consecutive year of growth.
Its popularity has been boosted with British Airways’ busiest ever summer as well as the first full year of services by low-budget airline Flybe.
Meanwhile new destinations including Basel, Bern, Cork, Mykonos and Santorini can now be assessed from Docklands and there have been extra routes to Milan and Luxembourg added.

During the past 12 months Edinburgh, Amsterdam, Dublin, Zurich, and Rotterdam clocked up the most passengers for both business and pleasure.
LCY chief executive officer Declan Collier said: “We are very pleased to have set a new record for passenger numbers which has capped what was a highly successful year for the airport.
“2016 will be an important year with the completion of our West Pier expansion project and the appeal for our City Airport Development Programme (CADP), which will be heard at a public inquiry later in the spring.
“Through simple infrastructure improvements - an extension to our terminal building, additional aircraft parking stands, and a new parallel taxi lane - our airport has the potential to be even more successful, provide 2,000 new jobs, unlock much-needed short-term airport capacity, double our economic impact for London to £1.5bn, drive the regeneration of east London, and improve connectivity within the UK and to Europe.”
The airport also retained its title of Best European Airport under 5 million passengers at the ACI Europe Awards, named Best Airport in London at the London Transport Awards and recognised as the UK’s top business for corporate responsibility when it took the inaugural National Responsible Business Champion title.
