Hey, a great company compared to AC and american carriers. BUT they abandoned their low cost structure with entry into the world's most expensive airport (YYZ) and other major airports, going toe to toe with AC. As a pax, check out their ticket costs, on par or more than AC in a lot of cases now, not many deals flying around anymore.
They are a major now and will be under attack by smaller co's that go back to the basic model with reduced costs, a la Enerjet. If you dispute that, your disputing what made WJ so successful in the first place.
I guess I should've said high"er" cost carrier, than it used to be. Apologies.
