Never having flown SU, never trasferred at SVO and never having flown economy cabin for trips longer than 6 hours I would like some advice from you guys: I just stumbled upon a great fare AMS - SVO -NRT of Euro 430. This includes a transfer of two or 5 hours at SVO which I think will be doable (not a big fan of SVO but ok-ish I guess) and a 9hr stretch on SU in economy. Any experiences? Will I be broken on arrival? Any thought on comfort, service and what to expect regarding fellow passengers? Any info welcome. Thanks!
