American Swifties are headed across the pond for the European leg of Taylor Swift's smash-hit Eras tour, which kicked off in Paris this week.
Why it matters: Swift's tour was credited with boosting local economies across the U.S. last year. Many European cities are anticipating the same boom.
By the numbers: Americans have snatched up 20% of the tickets for Swift's four sold-out Paris shows, the Associated Press reports.
About 10,000 Americans are expected to attend her Stockholm shows alone, per the AP.
The intrigue: Many American fans are taking advantage of cheaper tickets thanks to tighter European regulations on fees and resales.
