There are two points to that.
WestJet currently is operating under exemption for one in 50 in Canada. Actually, one in 50 has been used in Canada under exemption for many years in 50-seat aircraft. Aircraft certified under regulation in Canada are certified to one in 50; that's the international standard.
When we speak of Australia, we looked very closely at all regulatory jurisdictions. Although Australia may have regulations on the books for one in 36, they were the ones, as a regulatory environment, that set the stage for exemptions. Most carriers in Australia are operating under a one-in-50 exemption, which is the international standard.
Going back to safety management systems, the entire intent before you make change.... We have a saying at WestJet, “We do it with our people, not to them”. To the questions about incorporating the front line and their thoughts about it, our flight attendants were actively involved in this adoption of change at WestJet.
When we looked a step further, safety systems required to make decisions based on strong amounts of data, across the world there are only two regulatory jurisdictions not operating under one in 50. That was, to your point, Canada and Australia. We had reams and reams of data and lots of airlines to go to to validate the safety of the change. That's been proven, as we've been operating in Canada at equivalent level of safety, since October 2013, under one in 50.
