On the one hand, the adjustment of flight time in different seasons takes into account the low season of tourism and the periodicity of people's travel. According to different flight seasons, airlines will adjust existing flights in the new flight season with reference to flight income.
For example, Sanya has fewer flights after changing seasons in spring, because summer is usually the off-season of Hainan tourism and there are few tourists, so airlines reduce flights accordingly. In winter, it is very cold in the north. Sanya has a warm and pleasant climate, which is more popular in winter, and the number of flights will increase accordingly.
On the other hand, according to the actual situation of our country, the weather and air pressure in spring, summer, autumn and winter are very different, which leads to great differences in flight standards. Airlines adjust flights, on the one hand, for safety, on the other hand, for the convenience of passengers.
