As another example, let's say your flight is delayed or cancelled. You were coming to Ottawa, but another person on that same flight was going to Winnipeg, for example. Part of the APPR, part of the good customer service that airlines will do, is work with the individual passenger to accommodate. If there is an available flight immediately to Winnipeg but there is not an immediate flight to Ottawa, the two have two different circumstances, and therefore the blanket approach that I believe you're speaking to would not necessarily work in that case.
There's also the importance of due diligence. It's why we have a uniquely Canadian approach via the CTA. That due diligence is at the cornerstone of that.
