Low cruise altitude?
Was just tracking my friend's flight today from SVO to LAX on Aeroflot (SU 106), and notice the flight plan that was filed has the cruising altitude of only 29,000 ft. Does that seem a bit low for such a flight. I've flown a lot of flights between Europe and the US West Coast, and seem to recall they all flew at between 36,000 and 42,000 feet. Is there some advantage to the lower altitude? Equipment on this SU 106 flight is 777-300ER.
