This is what Gary Kelly actually told Wall Street:

(Earnings Call Q2 2018):

Gary C. Kelly - Southwest Airlines Co.

"Well, Duane, I think it's very fair to say that our primary focus is investing in Southwest Airlines. This year in particular we've got a lot of our major strategic initiatives behind us. There's always work to do. But, in particular, here in 2018 and my hope is 2019 and 2020, we're really focused on the quality and the cost-effectiveness of our operation, the hospitality of our customer service, those very basic things. We want to continue to grow the airline. We've got wonderful opportunities to grow. And the tax reform, obviously, is a nice little boost to our sources of financing.

So there's no imperative that we need to be hunting for an acquisition. I think that that's different than where we were in the late 2000s; 2009, 2010. And clearly this is our priority is just to grow organically. Having said that, we've always got to have our eyes open and be thinking about how we can improve shareholder value, and if there is a good opportunity in our view, it's something that we'll take a look at. We're always thinking about that, but admittedly that is not a focus and clearly not a focus right now."

I don't think we are buying anyone anytime soon, unless we got a sweetheart deal...at least not in the near term.
