Yes, Helene, actually it's none of the above would be the answer to the question. Look in the business of ours from one quarter to another, it's easy to draw a lot of prognostications, which probably aren't there. And as we see it right now, it's a particularly weird time. One, because so many -- so much of the U.S. airline business is still recovering their networks, and the networks that are being recovered are probably never been more divergent, never more different competitively, but also never more different than what was there three or four, certainly five years ago. And so a little bit of what you see is that. And what I would actually say is we, I'll echo the points I made and then Robert made me in the opening bit. As we look forward, actually we see a lot of opportunity. First of all, with our network, you know, as we look out there, we serve 300 cities in North America, in 200 of them, we have a network advantage. And as we bring back more of the regional jets, as we up gauge the mainline fleet, that's a real advantage for us, because so many of our competitors really won't be there. The customers in those cities are about 50% of our customer base, but they produce about 60% of our revenues. They're the ones who are signing up for the program for AAdvantage and enrolling in the card. And then the other big opportunity we have really across our enterprise, but it'll play out most notably in the domestic system, is really with AAdvantage, our travel rewards program. As we see it, our co-branded credit card is the largest co-branded credit card in circulation. Our program is one [Technical Difficulty] maybe travel programs in the business. But if you look at us, we produce probably $400 million less in frequent flyer revenue than what the industry leader does right now. So the quarter-to-quarter trends are just a function of things like the recovery. The real thing that we're seeing is the opportunity in the quarters and years ahead.
