If you wish to fly with North-Wright Airways, then you would need to book a flight out of Yellowknife because the airline does not fly out of Los Angeles. If you still prefer to fly out of Los Angeles, then there are other airlines to choose from, such as Canadian North.
Aklavik, Inuvik/Mike Zubko, and Norman Wells are the most popular airports North-Wright Airways uses on a routine basis throughout the year.
