The largest airports in the Europe

In present, almost all of larger towns in the Europe own airfield. The same is in USA, Canada or Australia. Buying flight tickets is a lot more usual for everyone, then it was fifteen years earlier. But there are few big airfields in the world, scales of it are sometimes larger then size of a little town. Airports like that are capable to send tourists to antipodes with one tour! They are so big, that sometimes you may need a map to avoid getting lost.
