Hey guys,
Spasiba Bolshoi for all of the input, I really appreciate it. I'm having second thoughts about my plan now...Are you guys sure the 4hrs is cutting it too close? I've heard from a family friend that if I were to take a taxi between the airports it would be between 1 to 1.5 hours depending on the traffic...The reason I mention taxi instead of the trains is because we may have heavy bags with us..So anyway, even assuming that the flight was late by, say, 45 minutes, we should theoretically arrive at VKO 1.5 hrs before the flight...does my reasoning make any sense or am I missing things?

Thanks again!
