| Prague to Hong Kong via Moscow. After 2 yrs again on this route. Web check-in did not work properly, so I had to queue in PRG, but processed fast. Outbound PRG-SVO leg with slight (30 mins) delay, usual drink + tasty dark bread sandwich. Only issue with Russian pax who always rush out of plane even before parked and push over the rows ahead (this is where crew should manage order), which causes stuck and safety issues. Swift transfer to terminal F (some 20 mins walk + passport check) in Moscow. SVO-HKG on the same plane like in the past, however not much worn and clean, good meal presentantion - tasty and filling - both dinner and breakfast. Drinks refilled upon request, bottled water + amenity pack distributed (no earplugs). Young and attentative FA´s. On the inbound, used again HKG express city check-in, no upgrade to C for HKG-SVO available (sold out). Flight again ok, relaxing and on time. First drink service before takeoff, hot towels before meals. I wonder why the crew did not offer paid uprage to Premium from Economy class in plane, as the PE load was some 30-40 % both ways on long hauls and this may bring additional gains. After almost 3 hrs delay in SVO due to heavy snow finally, the flight to PRG (last on evening) took off - we were not provided any meal vouchers or other assistance. Also the delay announcement was made some 5 mins before original boarding start when the plane at gate was directed elsewhere. Boarding by bus on remote stand to snow covered plane (another 1 hour waited for ATC clearance), in the A321 the phone charger (USB) did not work. Also the pax behind me caught all the time heavily without covering his mouth or being asked by the crew to do so - naturally I caught flu could not change the seat while packed economy class. When asked repeatedly and politely in SVO at the counter for C upgrade, I was just responded "No" without any other excuse or so (it wasn´t full though, I was in business suite, FF flyer, PE full flex ticket paid). Despite the last points, I´ll recommend to anyone from central/eastern Europe for Far East connections.
