Yes, thanks, Sheila. I'll take that. So, I think overall, you're right. At the current revenue levels, that would equate to about the range of SG&A reduction. I think the way we think about this is that, first and foremost, as we said earlier, we'll always prioritize safety, service delivery, pilots and maintenance, and the member experience, that's always going to be first and foremost. But at the same time, we also think we need to continue to make some investments in technology. We'll continue to do that. But I think as we think about that spending level, our goal is to reduce a lot of the overhead spend, be more focused on our marketing and advertising, and then deliver savings for -- by consolidating a lot of activities that are performed in a more decentralized manner today. We still have a lot of silos out across the organization. And I think there's ways that we can bring that activity together in a more centralized fashion, use systems and technology to automate it, and then that's really going to help us. I would say some of the sequential improvement we've already seen is the result of some of the actions. We've already started hiring and headcount freezes, reduced internal travel, and some headcount reductions. And then, we're going into our cycle right now to work on our 2023 budgets. So, we're doing a lot of work, looking at the organization, the organizational structure, and really developing that quarter-by-quarter cost framework that will execute and use in 2023. You asked about like the fuel, as well. I think in the third quarter, we saw about a $6 million benefit in terms of our cost structure related to fuel. So, we are seeing that fully indexed fuel surcharge now helping us mitigate some of that pressure that we saw earlier in the year. And we effectively look that. Now it's in place and ensuring that we shouldn't have any significant adverse impact from fuel fluctuations going forward.
