Why don't planes often fly across the Pacific Ocean?

Being recognized as the largest ocean on the planet, the Pacific Ocean always contains mysteries that make many people wary.

For passengers who regularly fly back and forth between Asia and the Americas, there is a question, but there is still no clear answer: Why do most flights avoid direct routes? Pacific?

Crossing the Pacific is not a straight line like we see on the map.

Even when flying from the US to Japan or South Korea, the aircraft often flies around to Alaska, but definitely does not go this route.

In fact, the main reason is still because of saving time and fuel. It sounds ridiculous, but the fact that crossing the Pacific is not a straight line like we see on the map.

Since the Earth is spherical, the distance between the two meridians when approaching the parallel is longer than the distance between the two meridians toward the pole.Selecting a roundabout route will help reduce the distance quite a lot.

Another reason is that flight routes must be designed to ensure that aircraft can communicate with radio stations on the ground and be ready for rescue if they are in danger.

Flying over the Pacific is very risky because there will be no airport for aircraft to land quickly before the possibility of an accident, not to mention the weather at sea is difficult to stabilize. than the mainland.
