Relatively speaking, the round-trip ticket price from South China City to Sanya is relatively cheap, and the round-trip ticket price from low-cost airlines to Sanya is relatively cheap; Because the north of China is far away from Sanya, the round-trip air ticket to Sanya is more expensive, and the round-trip air ticket of non-budget airlines or five-star airlines is more expensive.
There are many factors that affect the price of air tickets, and the relationship between supply and demand is familiar to everyone. The price in the tourist season will be cheaper than in the peak season; Airlines will also release low-priced seats first, and when the low-priced seats are sold out, the remaining prices will naturally rise. But in the near future, airlines may "tailor-made" different prices according to their own conditions.
Simple dynamic prices, you can take Uber, Raffles, or Didi as examples: in rainy and snowy days or during rush hours, prices will rise, but the car is still the same car, and the only change is the relationship between supply and demand.
