After helping boost the US economy with The Eras Tour, her record-breaking series of worldwide shows, Taylor Swift is now spreading her influence across Europe.

A report by online travel booking company eDreams Odigeo says Swift’s fans, known as Swifties, are spurring massive air travel demand to Europe.

Swift is performing multiple stadium tours between May and August, starting with Paris on May 9 and concluding in London on August 20.

Demand for flights to Stockholm between May 17 and 19, when the star is due to perform, has jumped six-fold from the same period a year ago, eDreams says. Meanwhile, demand for flights to Warsaw, Edinburgh, Liverpool and Paris on the days around Swift’s concerts jumped 339 per cent, 176 per cent, 133 per cent and 108 per cent, respectively.

Transatlantic demand has risen the most, the Barcelona-based company says, suggesting strong interest from American Swifties in the European performances.

Besides the top five cities, demand has risen in cities such as Zurich, Lyon, Milan, Amsterdam, Vienna and Madrid, where Taylor will also perform.
