Does Mapless work in Airplane Mode?

Sometimes you're traveling, you don't have Internet access. Mapless needs Internet access when you're searching for a destination. Once you add the destination to your history, Mapless won't need Internet access to point to it. 

Let's say you're traveling internationally. When you're in an Internet cafe, you can add a number of destinations to your history. Then when you're out and about, an no longer connected to the Internet, you can tap on any of the locations you just added and walk towards them.
