Worst airport I have ever been to in Europe. It to...

Worst airport I have ever been to in Europe. It took us 3 hours from landing and proceeding to our next gate for the transfer flight. Airport is huge but not well planned out. We had to take two internal trains and one outside shuttle. I m all for security, but this was ridiculous. We had to stand in lines and show boarding pass and passport 5 times before we got on the next flight. Getting off train there was a mass herds of travelers all pushing to get to some type of line which took over an hour. Last time that we needed to show passport and boarding pass was just 10 feet from prior check. Will never travel to to this airport again.
