Oh, wow. Well, we've been asked several variations of that question, although not that one exactly. And right now, I'll just ask our folks to stay focused. We have a very good plan for 2019. We're not at the point yet where we need to call any material audibles. We're working on -- the MAX is pretty much the audible that is tasking our group right now. I have not asked them to consider contingency Plan B, C, D, E or whatever it might be. So, I just don't have a ready answer to that question. I think all of us are working under a reasonable assumption that the MAX is going to return to service in a reasonable amount of time. And then, whether we're back to normal, sometime during the third quarter or to begin the fourth quarter, in the grand scheme of things, is probably somewhat immaterial. I think what all of us are a little more concerned about is if that goes on too long, we have a -- Tammy referred to this, so we have a retirement program. So, Jamie, I think what we would be -- what we would have to scratch our heads with more is just from an operational perspective, we've already planned retirements. And that would imply that capacity goes down from here. But we certainly don't want that. And it would be a lot of work for us to go in and unwind our retirement plan, and I do not want to do that. That would not be efficient. We've got better things to work on, quite frankly. You've asked a much broader, more strategic question. And that's a pretty -- that's an outlier in terms of a scenario. And I just don't -- I don't think that, that is anything that we'll be spending any time thinking about right now. But clearly, strategically, we're in a growth mode, so is the industry. We need to be growing. And we don't -- we -- clearly, we do not want this stagnation, to use your word, to continue very long. But I just don't have a ready answer on that question. And I don't think that, that is a likely scenario.
