Apologies if this has been asked before. I'm intrigued by the route taken by many long haul flights, which seem to a novice like me to be taking the "long way round". Example: Air Tahiti Nui A340 flying from Paris CDG to Papeete this morning flew over my house - in Northern England - albeit at 34000ft. I can understand that things like prevailing winds at whatever height, cost of fuel, the earth's rotation maybe, and a preference for flying over land wherever possible are all important factors... but I find the whole subject of long haul route determination to be quite intriguing. I did some googling but couldn't find anything particularly helpful. How do I get myself educated, d'you think?? All suggestions welcome. Thanks, folks.

JFK-HKG regularly flies almost straight north from JFK and approaches HKG from the north, befuddling quite a few of the passengers who only know about Mercator projections. The intial heading is 352 magnetic.
