Friday Now Cheapest Day to Book and Fly

Expedia's 2026 Air Travel Hacks Report reveals Friday as the cheapest day to both book and fly domestic flights, saving up to 8% compared to Sundays. Booking on Friday beats weekend rushes by 3%, while flying then tops Thursday and Tuesday. This shift challenges old wisdom, as business travelers fill Fridays, leaving deals for leisure seekers starting weekends early. Savvy travelers snag hundreds off trips to Las Vegas or Tokyo by embracing flexibility over rigid advance booking.
