When traveling from Singapore to the states wy do they fly through uk where they can fly through moscow which?

Answer 1

The air routes from the Far East to Europe and North America are covered by "Bilateral agreements" between the Governments of the countries operating the originating flights and receiving the incoming aircraft of other countires. The basic laws states that country "A" has the right to pick up and drop off passengers and mail in country B.

A flight from Singapore would have to be first route cleared by the countries over which it flies. So for exmple an A340 flight or B747 flight would be authorised to pass over the countries along its chosen route to Europe & the USA and flights from the USA by USA airlines go in the opposite direction and generally this takes them through the U.K -London, a stop/drop/pickup/commercial point as opposed to Moscow which isnt really.

Answer 2

Even flying through Moscow is long. A flight from Singapore to New York should take heading 358 which is almost north. So the best route is to pass over Malaysia, Thailand, north Laos, central China, Mongolia, central Russia, North Pole, eastern Canada and then the USA. However, flight routes unfortunately don't go this way. The best route would pass on Malaysia, Thailand, Burma, India, Pakistan, Afghanistan, Tajikstan, Uzbekistan, Kazakhstan, Russia, Estonia, Sweden, Norway, Iceland, Greenland, Canada and then USA. Different circumstances however might affect the choice of certain routes like weather, aeronautical charges, variable routes over the ocean, etc.

Answer 3

It's to cater to the huge volume of people flying SIN-LON as well. the SIN-MOS route is relatively newer and not so popular. Airlines stand to make more money.

Not to forget landing rights as well..
