I believe a big reason commercial airlines don't fly direct over it is due to regulations requiring them to have special safety equipment if they do. It's such a slight difference in distance that it's not worth it to them.

i has seen a youtube vid that had a variation on that - my first question was :
distance to the sun
distance to the moon
distance to polaris
i didnt get to ask the next question - as he obviously realised that he was walking into a trap - delected my comment and blocked me
Jet fuel freeze temperatures range between -40 and -50 °C. These temperatures are frequently encountered at cruise altitude throughout the world with no effect since the fuel retains heat from lower elevations, but the intense cold and extended duration of polar flights may cause fuel temperature to approach its freezing point. Jet A grade with a maximum freeze point of -40 °C is used in the U.S., while Jet A1 grade with a maximum freeze point of -47 °C is used elsewhere. Modern long-distance airliners are equipped to alert flight crew when fuel temperatures reach 3 °C above these levels. The crew must then change altitude, though in some cases due to the low stratosphere over polar regions and its inversion properties the air may actually be somewhat warmer at higher altitudes.
