The Airport Authority is celebrating the 15th anniversary of the first Westjet flight into Thunder Bay. Airport manager Scott McFadden says having the airline here has helped to make flying more affordable for many people. He says when inflation is taken into account, the cost of flying is still a fraction of what it was before the air carrier arrived here. And while Westjet isn't offering the same deals it used to, McFadden says they still contribute to a competitive climate.
