Sure, yes. Thanks for the question, Savi. I think an area that I get pretty excited about is in terms of helping improve -- or a tailwind to our unit costs, as I mentioned earlier, was on the ownership side. Just some of the deals that we're seeing or potential aircraft deals we're seeing coming our way as a result of the pandemic could meaningfully help us drive that down. In addition to that, from another tailwind perspective, I get pretty excited of what Sheldon and his team is doing on the ops side of the house, doing things to make sure we're running a good airline. It's expensive when you're running a not-as-good airline, so that's always helpful. We talk about Skywise and the investment in Skywise, which is our predictive maintenance platform. I think, the team today, we have about 25 aircraft that are retrofitted with complete capabilities of Skywise. By the end of the year, we think that will be up to 75% of our fleet, and then next year that'll be about 95%. I mention that, Savi, because that not only helps us run a better airline with dispatch reliability and things of that nature. It also allows us to handle maintenance when we want to, not in an unscheduled-type environment, again saving on costs. That's a really big deal for us. Where we're seeing some headwinds that we're looking at currently, and I don't know if this is here to stay, candidly, Savi, is on the station front given that -- with the pandemic and a few of our airports in which perhaps there was a budget deficit that they're going back and trying to reclaim that for the moment. We're seeing some pressures there, but I think, as industry capacity picks back up, potentially that could help kind of level that back off, all right? But what I'd say ultimately, Savi, is I think, where we're at from a cost perspective, we're in a good spot. We're not here saying we need to be at 5% -- or I'm sorry, on a 5-handle CASM-X. That's a nice to have, but candidly, if that was like our end-all, be-all, we would just increase utilization from 8 hours a day to 12 hours per day. We've been taught to look at this from a profitability perspective, and there's 2 sides to the equation. You have the revenue and the costs side. And so ultimately that's what we're doing, and we're going to focus on maximizing our profitability. And if down the road we need to spend $1 to make $2 or $3, we're willing to do that because that's where we're going to be keenly measured on, but I know that's kind of a lot of information. Maybe I'll pause there if I -- hopefully, I answered or helped answer your question or provide any other detail.
