New flights to Berlin and Copenhagen are being added by Ryanair from its Scottish bases next year.
The route between Glasgow and the German capital and Edinburgh and Denmark will both operate four times a week from next summer.
There will also be extra flights to destinations including London, Barcelona and Krakow, the airline announced.
There will be 10 routes from Glasgow, 16 from Prestwick and 33 from Edinburgh in Ryanair’s summer 2016 schedule.
The growth in flights across the airports will support around 3,000 jobs and cater for four million customers, Ryanair said.
Chief executive Michael O’Leary said: “Ryanair is pleased to launch our summer 2016 Glasgow schedule, with a new route to Berlin and four daily flights to London, and 26 routes in total which will deliver 1.7 million customers per annum and support 1,275 ‘on-site’ jobs at Glasgow International and Glasgow Prestwick.
“With a new route to Copenhagen, and more flights on nine other routes including our Edinburgh to London route to five times daily, we will deliver 2.3 million customers per annum and support 1,725 ‘on-site’ jobs at Edinburgh Airport.
“To celebrate the launch of our summer 2016 schedule, we are releasing 100,000 seats for sale across our European network at fares starting from just £19.99, which are available for booking until midnight Thursday.”
