I think about our priorities. I break it into two categories or two buckets if you will and Gary really hit on the first one which is – and we have work to do, to I get the classics retiring, get the Max in, we have work to do to get the new reservation system in and that's all going great. Things like that, the work is in progress now is a category of priorities. From my perspective, the second category is very much focused on bringing our strategy and our vision to life. There's a lot of work going on there. I think about our vision statement which you all know, it's very clearly a statement of our intent. We intend to do this. We know it's going to take time, we're okay with that, the business is very strong. As I said earlier, we have a lot of momentum, I feel very good about that and I think we have time to execute the strategy in a very structured thoughtful way and there are all sorts of things that might kind of work together. Let me just give you an example or two of some of the things and I'll see if I can disclose the strategy, but I'll give you a few examples of things. Very clearly, we could do a better job of enabling our front line employees with the tools and information that they need to do their job. That's a big deal in terms of driving efficiency, it's a big deal in terms of improving their customer experience and to be honest with you, it's a pretty big deal in terms of improving the quality of life of our employees, so we are very focused on that so there's work to do there. I think when we think about our customer experience, you will get tremendous praise and great feedback from our customers on our customer experience, but there are areas there that we can do better at. Just a few examples, I guess one I'd call out is we have a very strong mobile customer experience today which is a big deal for customers. 10 years ago, five years ago, not so much. Today, it's a very big deal. I think ours is good, I think ours is solid, but there's a lot of enrichment, and a lot of function, and a lot of stepping you bring to that. That's an example. One of the things that Mike and I – I've hit Mike on his shoulder here, one of the things that Mike and I are working on together is to continue to build out the operational capabilities and we're driving for obviously reliability. We're driving obviously for efficiency. But the other thing we need to be building for is scale; we need to make sure that the operating processes that we're putting in places scale as we grow and that's a big deal for us. So that's some of the things that I'm focusing on personally.
