Skyscanner recently analyzed its flight data and the results may not match what you’ve heard in the past.
According to their data, the best time to book a domestic flight is 30 days in advance and the best time to book an international flight is about four months beforehand.
Additionally, it found that the best time to find cheap U.S. tickets is in August. September is the cheapest month for international flights. As for the best time of day. It’s not Tuesday! It’s Saturday for domestic and Sunday for international.
Bonus Tip: Waking up early may save you even more. The best time of day to buy a ticket is 5 am. The earlier the better, if you forget to set your alarm don’t purchase tickets in the evening. 7pm-10pm is the worst time to book.
