Hi
Fly from Manch to Moscow quite often myself and have found the following to be acceptable:
1. Finnair via HEL. Nice airport to change planes at - no stress. Downside is that the connections or flights don't always suit.
2. BA via LHR. Upside is that BA arrive into DME instead of SVO which is a nice modern airport by Russian standards. Downside of course is LHR - 'nuf said.
3. CSA via PRG. A very convenient airport to change planes in and I have to say CSA impress me more every time I use them. fares also very competitive.
4. Lufthansa via FRA. As slick as ever always reliable.
5. Used KLM to RETURN from SVO in May. I can tell you that was excellent but I don't know if the outbound would have worked in connection terms.
All things considered I would recommend Finnair or CSA.
The trouble with flying to Moscow via anywhere is that it takes 'all day' if you count the time difference.
Roll on a non stop service some day!!!!!!!!!!!
