Make sure that it is very clear via the flight manifest that the plane is carrying dozens of American citizens besides Snowden and citizens from other countries. Fly the plane to the destination. If the US tries to force it to land, they can simply refuse to comply because there is no way that those leading this witch hunt would go as far as to risk causing a major international incident by shooting down the plane, causing a mid-air collision or causing some other air disaster.
