Continued demand for eastern European destinations served by Wizz Air and Ryanair helped push passengers using Glasgow airport up by almost 14% last month.
The Scottish airport handled more than 510,000 passengers in February – its 24th consecutive month of growth.
International traffic was up by almost a quarter over February last year while domestic numbers grew by 6.9% with British Airways, Flybe and Loganair all reporting a strong February.
Ryanair’s three daily services to Stansted also continued to perform well, according to the airport.
Aer Lingus launched flights to Donegal last month and Citywing confirmed an increase in services to the Isle of Man to 11 a week during the summer. Flybe launches a new double daily service to Bournemouth on March 29 and flights to Cardiff in June.
Airport managing director, Amanda McMillan, said: “Our success in securing new routes and attracting airlines to Glasgow has translated into sustained passenger growth and we could not have asked for a better start to the year.
“The next three months will see the launch of a further 13 new routes including direct flights to Las Vegas, Munich, Prague and Halifax, Nova Scotia.
“We are continuing to make improvements to the airport in order to accommodate this growth and are making excellent progress with the £3 million extension of our east pier.
“It is an exciting time for Glasgow airport and there is much to look forward to with major events such as the World Gymnastics and IPC Swimming World Championships still to come.”
