Almost three million passengers used Glasgow airport during the peak summer months of June, July and August.
The growth ensures that the airport remains on course to record its busiest year since opening 50 years ago.
More than 943,000 passengers were handled in August, representing a 7.4% increase on the same month last year.
Domestic traffic grew by 8.3% during August with Flybe, easyJet and Ryanair all reporting an increase in demand for UK services.
International traffic was up by 6.3%, helped by extra capacity deployed by Canadian carriers WestJet, Air Canada Rouge and Air Transat.
Scheduled services to Europe increased by 13.5% with Wizz Air, Blue Air and Air France, which joined the airport earlier this year, all showing strong demand.
Amanda McMillan, chief executive of AGS Airports and managing director of Glasgow airport, said: “August was an extremely busy month for the airport. We welcomed Scotland’s first direct service with Seoul which saw more than 1,000 South Korean tourists use Glasgow as a gateway to Scotland and events such as the World Pipe Band Championships also brought thousands of visitors to the city.
“Alongside our efforts in securing new routes for Scotland we have made significant progress with our £27 million investment programme.
“Construction of our dedicated car rental facility is underway and we will open a number of new food outlets in the coming weeks including celebrity chef James Martin’s new café.
“The launch of Ryanair’s Sofia service has helped us make a strong start to September. The airline has also confirmed it will further strengthen our European connectivity with the introduction in 2017 of flights to Lisbon, Valencia, Palanga in Lithuania and to the Croatian city of Zadar.
“The Davis Cup at the Emirates Arena and Celtic’s participation in the Champions League will also contribute to what we expect to be yet another month of growth for the airport.”
Meanwhile, Edinburgh airport achieved August growth of almost 12% year-on-year to almost 1.3 million passengers, helped by growing popularity of the Edinburgh Festival Fringe, according to chief executive Gordon Dewar.
“This summer at Edinburgh Airport we have welcomed more people into Scotland than ever before and people at home have better direct links with the rest of the world, this is great news for inbound tourism, the Scottish economy and jobs,” he said.
“This underlines the ongoing work we are doing at Edinburgh airport to adapt and accommodate the ever increasing number of people wanting to fly in and out of Edinburgh.”
He added: “We are currently holding a public consultation on an airspace change project and seeking views on the potential impact of altering flight paths above Edinburgh and the surrounding areas to allow for maximum operational benefits and to minimise community impact.
“Last week, following the well-publicised loss of some data for which we apologised, we have extended the consultation by an additional week; and I encourage as many people in Edinburgh, West Lothian, Fife, Falkirk and beyond to give us their feedback before the consultation closes on September 19.”
