Indeed, we will. But since you asked if that was going to be one of the routes I figured I'd chime in with my opinion.

Only 8x daily isn't enough to be a true Shuttle service. And as the fourth entrant in the market (I'm pretty sure AA still runs it, too) it would be mighty hard to keep up the numbers on that route. I'm betting they've got their eyes on other markets from each of LGA and DCA rather than just connecting the two.
