Almost 7.2 million passengers were handled by Glasgow airport in 2012, making it the busiest year since 2009.
The numbers travelling through the airport represent an annual increase of 4.2%.
Much of the growth can be attributed to the introduction of new routes and services to Amsterdam, Barcelona and Rome.
Domestic and international traffic for 2012 was up 2.1% and 6.4% respectively.
The growth in the annual figure was mirrored in December’s performance which saw passenger numbers rise by 4.3% over the same month in 2011. Glasgow airport handled almost 440,000 passengers in the month, with long-haul services up by 21%.
Managing director Amanda McMillan said: “We worked extremely hard throughout 2012 against a backdrop of continued economic uncertainty, to expand our route network and provide passengers with greater choice.
“We had considerable success in attracting services such as Emirates’ second daily flight to Dubai, which not only encouraged more people to fly to and from Glasgow but helped strengthen Scotland’s connectivity with important global markets.
“Whilst we are extremely encouraged at having exceeded the seven million mark, the current economic outlook is a cause for concern as are the planned increases in Air Passenger Duty, which will come into effect following the budget in March.
“However, we remain committed to working with our city partners throughout 2013 to secure further routes and boost the in-bound tourism potential of Glasgow.”
