More than two million passengers used Stansted in October as the airport notched up its 19th consecutive month of growth.
The October figure was 8.6% up on the same month last year as school half-term holiday boosted numbers.
It was the sixth consecutive month passenger numbers exceeded the two million mark, the first time this has happened since 2007.
The month also saw a record load factor for any October, with 88% of all seats occupied on each flight.
The total number of passengers using Stansted in the last year rose to 22.3 million, an increase of 15% over the previous 12 months.
Managing director, Andrew Harrison, said: “The significant increase in passenger numbers at Stansted continued during October as we enjoyed our 19th consecutive month of growth and welcomed over two million passengers for the sixth consecutive month.
“The busy half-term school holidays helped boost passenger traffic with an average 88% of all seats on every flight sold during the month. This enabled the airport to serve over two million passengers for the first time during any October since 2007.
“During the month we saw Scandinavian flag carrier, SAS make a welcome return to Stansted after a 14 year break offering new daily flights to Gothenburg from our newly refurbished Satellite One departure area that is undergoing an £8 million upgrade while in the terminal new passenger facilities including additional seating, new toilets and charging points became available.
“A number of new stores have also opened, including Hugo Boss, Superdry and Joules as the departure lounge phase of the £80 million transformation nears its completion.”
