Before I answer that I just want to make a little bit of a distinction, because I think it's important.
When we look at our statistics and at our performance in cases of denied boardings, it's important for us to recognize what is truly an oversell, meaning it was a commercial decision for us to oversell a flight as distinct from a case in which we end up overbooked. It may not seem important, but it's an important distinction to make.
Even if a flight wasn't oversold at all and we end up in a situation in which we have more passengers than seats, it might be as a result of irregular operation or because we had a downgauged aircraft. Irrespective of the reason, if we were in a situation in which we didn't have any volunteers on board—and even prior to the incidents in the spring this was in our provisions—we would never, without a volunteer, remove a passenger. By that I mean we would come on board and would ask for volunteers.
At that point in time, truth be told, the compensation level might change to such point in time as we got a volunteer. If we never did, our operations control systems would probably help us in looking to see whether there's an ability to upgauge an aircraft, but we would deal with the situation as events progress.
Generally, I have to tell you, we don't face that kind of situation when we have voluntary programs. We at times know that we have a situation coming, so we pre-move passengers. We contact them, we pay compensation in advance to move them, or we'll buy seats on another airline. A multitude of things can occur. In truth, I don't recall in my experience at Air Canada in revenue management having been through a situation in which we had no alternative. We always have alternatives.
