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. Getting flight tickets is a lot more common for everyone, then it was 15 years ago. But there are few big airfields in the world, sizes of it are sometimes larger then size of a small town. Airports like that are capable to send people to antipodes with one cruise! They are so big, that sometimes you will need a map to avoid getting lost.
