The twice-weekly Krakow service and four-per-week Mardrid route will both take off this October.
Amanda McMillan, managing director of Glasgow Airport, said: “This is extremely welcome news from Ryanair which has continued to respond to demand since the launch of its Glasgow base in 2014. Madrid and Krakow are two of Europe’s most popular city-break destinations and both routes have huge potential to generate significant in-bound tourism for Glasgow and Scotland.
"Madrid and Glasgow enjoy strong economic ties with companies such as Santander, Gamesa and Scottish Power all having headquarters in Glasgow so there will undoubtedly be strong demand for this service from within the business community.
"The introduction of Krakow brings the total number of Polish routes available from Glasgow to nine. As one of the oldest cities in Poland, it is often described as the country’s cultural capital so it will no doubt prove a huge draw for leisure travellers."
