Robin, we're not surprised by that. These are small business owners who need to get out to their customers who have to work hard every single day to keep their sales and their business moving. And we do see a meaningful continued improvement in small business traffic, some that we can measure, others that we can't say, they're not under contracts with us, but we know that consuming important part of overall business travel. But I do want to talk about the overall corporate travel results. As you probably know, we extensively survey our corporate customers, our large corporate customers on a quarterly basis, in addition to just being with them on a weekly basis as to their thoughts on the return of travel. And the most recent survey that we conducted, which just ended a couple of weeks ago, indicated that 40% of our big corporate customers expect they will be fully back to 2019 levels by 2022. And another 11% said that they expect to be fully back by 2023. So that's little over 50% of the customers and these are the people everyone's speculating what's going to happen to business travel, these are the customers who make those decisions, 7% said we'll never be back to 2019 levels, only 7%. And 42% said they weren't sure needed more time to figure it out. So with all the dialog and speculation around the depth of business travel, just looking at that survey, it's very interesting. If you take the 51%, that said they'll be fully backed by '23, the majority of which is in '22. And then you consider the second quadrant of 50%, who said they'll never return or they're not sure of their return. And even if you assumed only 50% of their travel returns; that gets you 75% of the way back no later than '23, and I think that's a very pessimistic view on business travel. So what we've been talking about corporate travel, business travel returning, I felt optimistic when I saw those results, we know it's going to be different going forward. As I've said many times, it could be 10% to 20%, lower over a period as it's substituted and complemented, there'll be different types of travelers, different reasons for people traveling. But I think business travel has got a very, very strong opportunity return over the next two years, and we're going to be well positioned to carry.
