Hey guys! My El Salvadoran boyfriend will be traveling to Bulgaria soon, a trip which takes 3 connected flights. He'll be staying for a month at most, maybe two--which doesn't require a Visa, only a passport, under Bulgarian law.

I was curious if anyone has made a similar trip from Latin America to an EU country, and what your experiences were concerning checks at the various airports as well as the destination. Were you asked a lot of questions at any of the connecting airports or when you were arriving? We also want to be sure there'll be no risk of his being denied access to any of his connecting flights because he doesn't have a VISA within the European Union. (His connecting flights may well include USA/Amsterdam/Heathrow, depending on the ticket he buys.)

Thanks a bunch!
