Traveling to the United States by plane, why do planes prefer to fly around rather than cross the Pacific Ocean directly?

Friends who travel from China to the United States, if they travel by plane, will find that the plane flies north first and then east. This flight mode appears because it is convenient and safe.

Misunderstanding of geography. As we all know, the straight line between two points is the shortest, and it seems that the distance from China across the Pacific Ocean to the United States is also the shortest, but this theory is based on the plan. But the earth is a sphere. If China and the United States are in a straight line on the earth, they will form a semicircle. When expanded, it does not represent the shortest distance.

It's not safe to cross the Pacific Ocean. Our country and the United States are separated by a Pacific Ocean, and we will fly across the Pacific Ocean to the United States. However, there are few countries in the Pacific. Although there are some islands, the infrastructure conditions are not very good. If the plane flies directly over the Pacific Ocean after take-off, when the plane breaks down, the passengers on the plane face the vast sea, and the ground is useless every day, and there is no parking place at all. Once a major flight accident is caused, no airline wants to see this situation.

Can save money. The plane takes off from China and flies north. This route is just in the westerlies, and the flight from China to the United States is just in sail before the wind, which reduces flight resistance, saves a lot of flight costs and reduces flight time. Under this flight route, compared with just seeing the endless sea, you will see all kinds of beautiful scenery such as the North Pole, killing the boredom and loneliness during the flight. In this way, we can not only realize the double benefits of time and money, but also have beautiful scenery. Why not?
