Americans flock to Taylor Swift's Eras Tour in Europe

• A bonus: Many fans are taking advantage of significantly cheaper ticket prices, thanks to tighter regulations on fees and resales in Europe.
• Americans have already bought up 20% of the tickets for Swift's four sold-out Paris shows, per AP.

The intrigue: The Eras Tour shows in Paris are also attracting five times more luxury travelers from the U.S. than anticipated travelers for this summer's Olympic Games in the French capital, Bloomberg reported.

• About 10,000 Americans are expected to attend the Eras Tour shows in Stockholm alone, per AP.

Tickets for Swift's remaining U.S. shows — in Miami, New Orleans and Indianapolis — have skyrocketed since she dropped her latest album "The Tortured Poets Department" last month.

• The average lowest ticket price is a whopping $2,600 per ticket, Billboard reported, citing data from TicketIQ.
• By comparison, the average lowest ticket price for her Paris kickoff show is $340 per ticket — about 87% cheaper. Tickets are even lower on some of her other stops, like Stockholm and Lisbon, per Billboard.

Zoom in: In many of Swift's planned European stops, hotel and short-term rental prices have spiked and seen increased booking rates well in advance of her arrival, the Guardian reported.

• Stockholm's Chamber of Commerce said in March that it anticipates the Eras Tour shows to pump more than $46 million into the local economy.
• It'll be a "real hit," according to chief economist Carl Bergkvist.
