The -- Ravi, the airline industry, there's always -- it's not for the faint of heart, right? There's all kinds of things in front of you. I don't know that I tend to think of it the same way. We have -- I kind of go into reverse here, and then I'll come to your question. If you look at just the past six months, and where we were. So we've gotten staffing stable. We were on our hiring plans. Obviously, we have work to do with pilots, but we are in so much better shape. We've gotten operationally stable, same thing. We want to do better, but we are in so much better shape. Our cancel rate in May and June was sub 1% better than 2019. We just had a record quarter, record operating revenue. So it's just -- we're hiring 1,500 people. There's so many things to be grateful for in terms of the pace of getting the airline from kind of surviving to being really stable. Now we want to move into the next phase and really move back into operational excellence and other things. But now to really answer your question though, I do think there's no one thing on the horizon. There is -- if you just sort of click through them, there's risk in hiring enough pilots, but we're filling our classes. We have a lot of folks in the pipeline. The SIMs are full, the classrooms are full. We have all our flight instructors, checked, I feel good about that. You have our -- this new delay in deliveries from Boeing, but we're working really closely with Boeing and I feel like we're on top of that. And at the end of the day, we can fly our schedule. So it's not going to force a reduction to the schedule that's been published, which is just terrific for employees and our customers. I guess the biggest thing is just not one thing, but it's just all the uncertainty on the horizon. So you've got a recession potential, and you've got a lot of variability in fuel prices, huge variability and volatility and crack spreads on fuel, you have potential variability in demand because of all those things supply chain issue still. So who knows whether those will materialize or not. The good thing is, we are extremely well positioned. We have the people we need. We have the aircraft we need. We have a $6 billion net cash position. We have 53% leverage and -- so we're well positioned to weather whatever comes our way. So I don't -- I didn't specifically -- I didn't name one thing, but I've just given you a flavor for how I think about it.
