Glasgow airport achieved its busiest November in six years after almost 514,000 passengers were handled.

The figure was 3.1% up on the same month last year, helped by strong demand for long-haul routes including Emirates flights to Dubai and United Airlines’ Newark service which contributed to a 10.9% increase in international traffic.

The decision by easyJet and KLM to add extra capacity on their respective Amsterdam services for Celtic’s Champions League clash with Ajax also contributed to the marked increase in international traffic.

Airport managing director Amanda McMillan said: “Not only have we been able to report our busiest November in six years, we enjoyed our tenth consecutive month of passenger growth.

“We have been consistently growing passenger numbers over the course of the past three years and much of our recent success has been driven by the performance of our international routes, which is particularly pleasing.

“We are looking forward to what promises to be a busy festive period after which our attention will turn to 2014 and to delivering a successful and memorable Commonwealth Games.”

The second phase of Glasgow airport’s £17 million investment programme, which will transform large areas of the terminal ahead of next year’s Commonwealth Games, is underway. The works include an extension of the international arrivals area, new seating and the landscaping of a new public space at the front of the building.

Other aspects of the refurbishment include new flooring in the airport’s domestic pier, new heating and ventilation systems in terminal two, and general improvements to the airport’s road network and airfield.
