When I flew Transaero on London-Moscow route three years ago, we had a stop at Riga (capital of Luthiania). The advantage of this, apart from extra duty-free shopping, is double-meals
My pal flew Moscow - London a month ago and they flew non-stop. He couldn't tell the aircraft type (he's ignorant to aviation, grr...) - but I assumed from his descriptions it's an NG 737.
The B737-200s they operate seemed clean but could've been better. But what do I know about 737-200s... flown the same type with AF and still thought they could've been clearner. Maybe it's age that affects the aircraft's interior impression.
