The airport recorded its 30th consecutive month of passenger growth in September with a 15.6% increase compared with the same period last year. In total, a record 1.4 million passengers chose to fly from LLA last month.
Nick Barton, CEO of LLA, said: "Reaching this huge milestone is a fantastic endorsement from our passengers as they continue to choose to fly with us.
"Demand for air travel at LLA is at an all-time high which is an indicator of the timely nature of our transformation project.
"We’re working hard to deliver our £110m redevelopment and create an airport that exceeds our passengers’ expectations."
To meet this continued demand LLA is currently undertaking a £110m redevelopment project which will increase annual capacity by 50% to 18 million passengers by 2020.
