According to some self-media and video reports, a large number of routes between China and the US have been cancelled. Among them, United Airlines once again cancelled flights to mainland China on a large scale. Starting in March, 161 flights were cut, and nearly 70% were cancelled, including several flights from New York, San Francisco, Los Angeles, Chicago, and Washington to mainland China. After checking United Airlines' official website, it was discovered that the cancelled flight was not a China-US route currently being implemented, but a China-US route that was previously entered into the reservation system but was not approved for execution. Currently, flights between China and the US are still being carried out in accordance with the latest notice between China and the US in November 2023, but it is expected to increase significantly this year.
