When is the cheapest air ticket from Harbin to Haikou?

This ticket is the cheapest in off-season.

Off-season refers to a period when tourism demand is relatively low. In order to attract more passengers, airlines will take some promotional measures, such as reducing the price of air tickets. In addition, the passenger load factor of off-season flights is relatively low, and airlines will fill seats by lowering prices to maintain the operational efficiency of flights. After the National Day holiday and before the arrival of the winter tourist season, the flights departing from Harbin will enter the off-season.
