Taylor Swift's era-defining "Eras" tour is flying like a jet stream, high above the music scene — by billions of dollars. The tour could gross $2.2 billion in North American ticket sales alone, according to August survey data from research firm QuestionPro provided to CNN exclusively. That unprecedented total represents primary ticket sales for the US shows that Swift just concluded in Los Angeles, plus a second North American leg coming next year. The estimated totals are the latest example of the incredible demand for entertainment and experiences that has helped boost the economy, and is more specifically, a staggering show of Swift's star power and influence on local US economies.
