Okay. I'll start, and Gerry or Andrew can add. The biggest issue that we have well, first on capacity is we don't have a labor shortage. We've hired 6,000 people this year. We're hiring 200 pilots a month. That's not an issue for us. The biggest issue is 777. That's 10% of our capacity, and they're grounded. The other issue is just we're realizing that the whole infrastructure is not set up to snap back to these rapid growth rates. I mean it's not just us. It's the FAA, TSA, fuel vendors. There's all -- even if we have enough people, which we do, all of those constraints get in the way of a reliable schedule. And we're just not willing -- we made so much progress with customers during the pandemic and really building the United brand. I think that's going to be the most enduring change that we're not willing to sacrifice that customer goodwill for the possibility of short-term profits. And so -- and month-to-date, we're number one in on-time performance, number one in completion factor. So it's paying off for our customers. The pilot shortage, I'll to give you some numbers. So we did a deep dive on pilots because we're trying -- all of our regionals weren't able to hire and are having problems. And I think we've got 150 airplanes grounded right now. They're never going to come back, I assume. And so we did a really deep dive on it. It turns out that the industry over historically produces between 5,000 and 7,000 pilots a year, mostly closer to 5,000, but can produce up to 7,000 pilots per year, got a little lower during COVID. This year, the industry's intent is to hire 13,000 pilots. And given the growth aspirations of other airlines, it's even more next year. But there are only 5,000 to 7,000 available. That was an epiphany for us. And by the way, that probably can't be fixed quick put. You could set up flight schools to get people to $25 you get their first license pretty easily. But they got to get from 25 hours to 1,500 hours, and that just doesn't exist today. So in that 5,000 to 7,000, like over a few years, that 7,000 could probably go up. I don't think it's getting to 13,000 anytime in the next five or six years. When you look at that 5,000, if it's a 5,000, United Airlines is literally going to hire half of them. Half of them are to United Airlines. So this is, I think, underappreciated factor, and it's just not quick to fix.
