With the booming tourism industry, more and more people are choosing airplanes as a means of transportation for long-distance travel. Accurate low-price forecasting of air tickets helps the aviation industry to match demand and supply flexibly and make full use of aviation resources. Airline companies use dynamic pricing strategies to determine the price of airline tickets to maximize profits when selling airline tickets. Passengers who choose airplanes as a means of transportation want to purchase tickets at the lowest selling price for the flight of their choice. However, airline tickets are a special commodity that is time-sensitive and scarce, and the price of airline tickets is affected by various factors, such as the departure time of the plane, the number of hours of advance purchase, and the airline flight, so it is difficult for consumers to know the best time to buy a ticket.
