There is a clear orange sheet thingy on his headrest. From what I know, this is an EasyJet seat which is a european airline that flies within Europe. You can see the route map here

This image was posted 6 hours after he posted his first airplane image. Assuming that he started in Moscow Russia with the first image, and that he is flying inter-europe using easyjet, we can assume he landed somewhere around Berlin ( MOSCOW -> Berlin flight is 5hr 40m according to google maps). Since he has another flight, we can conclude he is going to some european team probably in britain or france or spain since he wouldnt fly to berlin then fly backward towards russia.
It is very possivle that we see G2 nats
