For these reasons, planes avoid crossing the Pacific Ocean

Long-haul flights usually try to avoid flying too much over the Pacific Ocean, which is the largest ocean in our planet, which occupies a large proportion of the Earth’s surface.

Why do planes avoid the Pacific Ocean?

The “Executive Flyers” website said that flying over the Pacific Ocean takes more time on any flight, which costs planes additional expenses.
In addition to cost considerations, airlines must also consider safety.
Long flights carry with them the risk that if someone on board has a medical emergency, there may not be a safe place to go to in time for help.
In the event of a plane crash, the worst place for this to happen is the Pacific Ocean, because the area is very wide and the chance of finding the passengers is almost non-existent.
In addition to safety concerns, the weather over the Pacific Ocean is actually very unpredictable, and there are many thunderstorms that occur over the ocean that can lead to disturbances.
Most planes avoid flying over the Pacific Ocean as much as possible, because it is like a battlefield in terms of weather.
Additionally, jet streams are an important factor in flight planning because they are essential in reducing fuel costs and time spent in the air. Jet streams are strong winds that blow from west to east across the planet and are formed when warm air masses meet cold air.
Airplanes can fly in these flows and get a boost when flying in the same direction as the flow, and over the Pacific Ocean, it’s the other way around. The plane is flying against the jet stream, so the flight takes longer.
Because of all these reasons, the Sheffield School of Aeronautics writes that the only regularly flown flights across the Pacific Ocean are westbound flights from the US West Coast to Australia, and the duration of such flights can be up to 14 hours.
