The Pacific Ocean is a massive body of water that will require an extremely large amount of fuel to fly across. Rather than flying directly across the Pacific Ocean, most commercial flights take curved routes because they are actually shorter than shooting straight across a distance.

Most of the carriers still overflying Russia, however, are based in Asia and the Middle East — many of which are household names like Qatar Airways, Air China, Etihad Airways, and Emirates. And, some of these routes are even flying to and from the US.

When flying over land, of course it is more likely that there will be more airfields closer to the aircraft at any given time. However, because of lessons learned from its history and the improvements in aircraft and engine reliability, crossing the oceans is deemed as safe as flying over land.

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.

The short answer is, no, it's not illegal to fly over Antarctica. But there are practical considerations that make it challenging for regular airlines to navigate across the land. In many parts of Antarctica, there's limited or no infrastructure, no landing strips, and obviously no refuelling stations for planes.

Dubai-owned Emirates is one of few major airlines to continue its direct flight service to Russia as other carriers cease operations over Moscow's invasion of Ukraine. Still, the United Arab Emirates has been reluctant to take sides in the ongoing war, and has so far resisted sanctioning Moscow.

The US prohibits flights across all North Korean airspace, including the oceanic part of the ZKKP/Pyongyang FIR over the Sea of Japan. Several other countries have airspace warnings in place which advise caution due to the risk posed by unannounced rocket launches.

The planes of European airlines, like KLM and Air France, are therefore not allowed to fly over Russia.

Despite what many people believe, the answer actually has nothing to do with safety. The real answer is because going north may actually provide a shorter route. This is called Great Circle Navigation. Because of the curvature of the Earth, the shortest route between two locations may appear much longer on a flat map.
