Routing doesn't realize I'm flying

[bmtphoenix]

When flying around in Northrend, and I set a waypoint, Carbonite tries to point me to the various zone borders as if I'm walking and have no flight points.

Other than that, totally flawless so far.

Edit: It's as if Carbonite usually intelligently disables Travel Routing when I'm flying, but either can't tell I'm flying, or isn't making that adjustment.
