CheapAir.com announced the results of its annual airfare study on Wednesday, analyzing 917 million fares from nearly 3 million trips to determine when the best deals are typically available for domestic flights in the U.S.
Based on their data, the best time to buy is roughly 70 days before departure. It’s a pretty significant increase from last year’s study, when the site reported most inexpensive fares could be found 54 days in advance.
