Expedia: Friday Now Cheapest Day to Fly, Book

Expedia's 2026 Air Hacks Report reveals Friday as the new cheapest day to both book and fly, upending old wisdom that midweek or early bookings save the most. Savvy travelers snag up to 8% savings by flying Friday instead of Sunday, with Tuesdays offering the lowest domestic fares at 14% below peak days and fewer crowds. Domestic airfares rise 3% this year, but booking 15-30 days out shaves $130 off compared to six months early, while July and October deliver prime deals.
