Lost in Translation

I just bought airline tickets at the local EgyptAir agency. As I sat at the desk, waiting for the agents to process my American Express card (I'm pretty sure that no one had ever purchased tickets at that particular venue using an AMEX, but then again, it isn't Egyptian Express), I noticed EgyptAir's English motto: "EgyptAir: The Sky's NOT The Limit." What does that mean? Will I be jetting to Istanbul for the weekend via the International Space Station? Or is it something more...worrisome?
