How long in advance is it generally the cheapest to buy a New Year ticket?

About 60-90 days. The cheapest air tickets are usually purchased 60 to 90 days in advance. This time period is usually the starting time for airlines to release tickets, and it is also the time when ticket prices are relatively low. At this time, the airline has not fully determined the demand during the Spring Festival, so it will provide some more favorable air tickets. If you decide to travel during the Spring Festival, you can buy air tickets within 60-90 days. In this way, we can not only get lower fares, but also choose the ideal flight time and seats.
