With the increasing number of high speed trains services in Europe, airlines are facing more competition on some routes. A growing number of people are taking into account their own 'carbon footprint' and train companies are keen to promote their 'green' credentials compared to travelling by air to win over passengers. Shown is an Air Berlin Airbus A320.

One of the advantages of travelling by train is that railway stations tend to be located in the centre of a city, whereas airports can be in the suburbs. In addition, some low-fare carriers fly to secondary airports that can be some distance from the main city destination. One such airline is Ryanair that serves a number of this type of airports, such as Brussels South Charleroi and Frankfurt Hahn.
Ryanair has stuck to its business strategy since adopting the no-frills approach and has reported some impressive profits. The airline continues to grow, with an ever-expanding route network and fleet of Boeing 737-800s.
