Dont fly London to Vancouver it is more expensive to get to Alaska from Vancouver. They transfer you from Vancouver down to Seattle then you are on yer way. You can get a flight from Seattle to Fairbanks for $300. Just remember everything gets expensive the further north you go.Good holiday insurance is vital as there isnt a hospital around every st corner
