Scotland's biggest airports welcomed record numbers of passengers in May.

Glasgow Airport had its busiest May on record after more than 910,000 passengers travelled through its doors - an increase of 10% on the same month last year.

International and domestic routes were up 16.5% and 2% respectively because of additional capacity on airlines including Thomson and Thomas Cook.

There was strong demand for European city destinations including Eurowings' Dusseldorf route and Ryanair services to Brussels, Sofia and Valencia.

A recently launched Lisbon route by Ryanair is said to have performed particularly well as hundreds of Celtic fans travelled to the Portuguese capital to celebrate the 50th anniversary of the club's 1967 European Cup win.

Long-haul services were also up by 15% because of an increase in demand for North American flights including Florida and Emirates' double daily service to Dubai.

Amanda McMillan, managing director of Glasgow Airport, said: "May was an extremely successful month which saw the launch of Delta Air Lines' inaugural New York-JFK route and new service to Bergen and the Isle of Man.

"Strengthening our EU connectivity continues to be an area of focus, so Lufthansa's recent decision to expand its current seasonal weekly service to four flights per week all year round was extremely welcome news."
