I’ll take that Fadi. I think -- but we don’t have a number for it. But if you think in the initial course, for example, on the supply and aircraft, typically, you might spend, if you look at your business aircraft, you take, say, three, four weeks at the training center. And you’re doing probably the equivalent of two and half weeks of that sitting in classroom, that’s just ballpark, okay, it depends by aircraft. The rest, you’re doing seven, eight rides in the simulator. So -- I mean, that can give you some idea. But when we when we talk about the restructuring savings that we have and achieving permanent cost reductions going forward, the $50 million we talk about. Some of that is basically take advantage of some of what you just talked about. We’ve learned to do a few things virtually during the pandemic. And at the same time, we’ve been investing quite substantially digital over the last couple years. And we announced our project digital intelligence, if you remember, of $1.5 billion invest in R&D a couple years ago we launched in Montreal. That by the way is why that investment is why we can turn ourselves around and go virtual really overnight, because of the ability to do that. But now post COVID everything’s going virtual. Okay. I shouldn’t say that. But the world is obviously going virtual. But definitely, it’s digitization if I multiplied maybe just exaggerating for effect, we did increased tenfold. So, the investments that we make here, the processes, leverage and digital, is going to have substantial impact on how we deploy, train in the classroom, specifically, how we deliver simulators as well. So, all these things that we’re going after getting permanent savings that’s where you’re going to see it.
