A friend and I, both American, are flying from Latvia to Moscow VKO on AirBaltic with a 2 hour layover then flying Transaero from VKO to Beijing. We do not have a Russian transit visa so we must remain in the Airport transit zone until boarding the connection for China. I am concerned, however, that we will have an issue boarding a flight with a different airline--say, it flew from a separate terminal or, worse, we needed to exit the transit area to check in with the other airline.
We will not have checked luggage, as I know this could add a further level of complication.
Any insight? Thanks.
