It's very good question.
The answer is no, not at this time. The only way that we did it pre-pandemic was with overtime, and as I mentioned in my opening remarks, Nav Canada's overtime bill for the previous year was close to $100 million, certainly not all for us, but I would say that the vast majority of that was for air traffic controllers.
The system was running on empty. That's probably the easy way to say it. Now, as we embark on a recovery, we're 18% short, potentially over 20% depending on layoffs or if Nav Canada follows through. I think those numbers pretty much speak for themselves.
