I'm trying to find the cheapest way to get from Seoul to Barcelona during a very busy time of the year.
I found relatively cheap return tickets from Seoul to Vladivostok. I also found a cheap return ticket from Vladivostok to Barcelona.
Is it possible to transit from one flight to the other without having to go through customs? That is, without Russian visa?
I will have carry-on luggage only.
If not possible through Vladivostok, I could do the same through Beijing, but it will be a bit more expensive and the flight hours are less interesting. And more risky as time between flights is shorter, and I assume I won't be protected if any delay occurs.
