Fans who came from overseas for the Swift's two dates at San Siro numbered more than 18 thousand, 14% of the total audience. And the induced revenue from the concerts on Milan is 180 million euros. Taylor Swift is the most-listened-to artist in the world, and her origins on her mother's side are in Cilento, Campania. "We are Swifties in Italy."

Flying from the US to Milan for Taylor Swift's concert is not only a pleasure. It is also a financial savings. "Tickets for the U.S. tour cost $800 to $2,000," says Dana Marlowe who arrived in Milan from Washington. She took a selfie in Piazza del Duomo and has a ticket in her pocket to visit Leonardo da Vinci's Last Supper.

"To kill two birds with one stone" is the mantra of the host of fans who preferred to follow Taylor all the way to Italy by taking the opportunity for a vacation. With $2,000 here, one not only attends the concert, but even pays for the plane and hotel. "Even if we had bought the cheapest resale tickets in our U.S., the cost would be close to what we spent to get here to Europe, travel and have a great summer vacation."

According to Airbnb's latest data, globally, bookings made in 2023 and early 2024 to come to Milan during Taylor Swift's tour are up more than 250 percent over the same period last year. Also considering fans from abroad, more than one in four bookings come from the United States, with an increase of nearly 600 percent of U.S. tourists to Milan compared to the same period in July 2023.

But in recent hours the numbers may even be growing. Overseas, fans are mobilizing to make last-minute arrangements. Virtual families have sprung up on social media to exchange information and find last-minute tickets. The Facebook group "Taylor Swift Eras Tour Milan" has more than 4,000 people signed up.
