I'm happy to answer the question. Thank you.
As it was mentioned earlier on, when we take a look at building toward our peak season, we take a look at the schedule we intend to operate. We take a look at the fleet, we take a look at the crew and we take a look at all aspects. We build resiliency into the operation, so that we have the flex required. We had spare aircraft and we had no shortage of operating crew.
In Calgary, in particular, our primary issue with the weather wasn't what we saw in Vancouver and Toronto. It was the tail end of almost three weeks of extreme cold, and that takes its own toll on the fleet, in particular. From this perspective, we saw higher requirements to use our spare aircraft for recovery, maintenance issues and things like that.
We had strong resiliency built into our network schedule.
