Did some research. There are no direct flights from moscow to either Quito nor Guayaquil. The closest international flight would be via Amsterdam, the netherlands. So i guess he’ll get a special purpose direct flight on either a russian or ecuadorian government airliner.
That would be a bad choice. He'd have to trust the Dutch.
He's probably booked on Aeroflot flight SU 150, a non-stop departing at 14:05 (06:05 Eastern, real soon now) and arriving at 18:45. That will put him in Havana, from which it is easy to reach Ecuador.
As CINC, Zero could order the flight diverted. But there would be risks. Zero doesn't like those.
And, who knows? Maybe I'm wrong, and Snowden's on a different flight!
