The growth of low-cost carriers (LCCs) is currently focused on the Western European market, where they represent the most deter- mining factor in the evolution of airline networks. In this area, they stand for 18% of the total air transport supply according to seats. Limited to short and medium haul flights, networks are not too concentrated (no hubs). They are North–South, and compete with— when they have not replaced—some charter routes. The use of air freedoms beyond the fourth is still limited, but exclusive routes are a frequent phenomenon linked to the option for secondary (urban or regional) airports and/or niches.
Finally, low-cost carriers give fresh impetus to point-to-point routes by drawing new networks complementing those of full service net-
work carriers (FSNCs). If no hubs as such can be found in these new networks, significant concentrations characterize the major bases.
The geography of low-cost networks is to a large extent the geography of EU air transport liberalization.
