From the moment they picked us up from Yellowknife Airport to our three consecutive nights chasing the Northern Lights, and then dropping us off at the airport again, the entire process was meticulously arranged. What was most appreciated was their proactive assistance after learning our return flight had been cancelled; the travel agency staff had already completed their task by dropping us off at Yellowknife Airport, but they still did their best to help us after learning we were stranded there. We are truly grateful!
