Isn't it clear in this news that domestic airlines have done a lot of hedging on jet fuel, so when oil prices fall, they will lose money. In fact, foreign airlines also do hedging, but they also have an insurance that can reduce losses, but there is no such insurance in China. In addition, airlines lose money not only because of oil prices, but also because of many other factors. For example, Olympic Games, exchange rate, economic reasons and so on.
