Airlines have a high proportion of foreign currency liabilities, and the appreciation of RMB will cause one-time exchange gains; At the same time, it also reduced the price of imported jet fuel.

The influence of the change of national income on the exchange rate depends on the reasons for the change of national income. If the national income is increased by increasing the supply of goods, the purchasing power of the country's currency will be strengthened and the foreign exchange rate will decline in a long period of time;
If the national income is increased by expanding government expenditure or total demand, the excess demand must be met by expanding imports under the condition of constant supply, which makes the foreign exchange demand increase and the foreign exchange rate rise.
