So, as we look at it, and this gets into the comments that I had made earlier is, there's a lot of activity taking place relative to just distribution in general, and it does get into how carriers are looking at driving more revenue, really getting into dynamic offers and capabilities that are out there. The one thing that we continue to talk about, and I think it's important to understand, is that making that step, which really gets into more of a direct connect, does not really address the costs associated to how do you actually make that work within an agency, the mid- and back-office capabilities and the costs associated with that. It's why, when I look at the broader opportunity and look at essentially where we're focused, it is much in line with making sure that we're helping enable them to do what they want to do, and it's not only American Airlines but there's other airlines that are out there. And I think what we'll continue to find is that the best way of actually selling products and services is through the GDS, but we need to continue to invest in capabilities to be able to do that. The one thing that we've often talked about is, when you look at ancillary revenues, the vast majority of ancillary revenues are sold through the direct channel, meaning through the airline.com. So now I'm talking probably 90%-plus. This is where we see a real opportunity to continue doing – hence, our selling through the GDS is the enablement of that taking place. But, again, it's working with each of the airlines out there and what they're trying to do. I will add just another comment is, as we look at NDC and what's taking place with NDC, because I know that's top of mind for a number of individuals that are out there, there are a number of conversations that we have as it relates to what carriers want in NDC. And what I will tell you is it is different by each carrier. The other thing that I will share is, if you look at essentially the standards that have been put out there, there's been 17 standard changes in the last four years and this is one thing that we have been focused on, as we have to have specific standards or standards that stay really consistent that we build to. And in doing that, the thing that I – as we look into the future, it's making sure that we're just not building one-off solutions for specific carriers, that there is a more of a prioritization of what needs to be developed and when it's developed.
