When it comes to questions of the largest airlines or busiest airlines, there are different ways in which you can rank them. You could rank them purely in terms of the size of their fleets, for example. You could also list airlines ranked by size based on the number of flights operated or the amount of profits they make. 

For this list, of largest airlines in Europe, we'll focus on one of the most important metrics: the number of passengers per year. Each airline will be ranked from 1 to 10 based on the amount of people they fly. So, without further ado, let's take a look at Europe's busiest airline companies.
