Do any flights go over the Arctic Ocean?
There are flights over the Arctic Circle and North pole between Asia and North America. Pilots adjust their flight route for winds aloft. It's common to deviate south of the arctic circle on an eastbound flight because a plane can take advantage of a trailing jet stream to save fuel and time.
Do any commercial flights go over the Pacific Ocean?
Due to all of these reasons, the Sheffield School of Aeronautics writes that the only flights that regularly fly directly across the Pacific Ocean are westbound flights from the west coast of the United States to Australia — and these flights can be up to 14 hours long.
Can pilots talk to ATC over ocean?
When communicating between a ground-based station like Air Traffic Control and an aircraft, the distance is somewhere in the middle. So, with an aircraft at 36,000 feet and the ATC radio tower at 100 feet, communication will be possible up to 250 nautical miles away.

What planes fly in Class A airspace?
The Class A, or Class Alpha category of controlled airspace is the high-altitude enroute airspace for jet and turboprop aircraft. It is the most restrictive airspace category with numerous entry and operational requirements for both pilots and aircraft.
Why do planes do not fly over the Pacific?
The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.
