The paradigm of airport planning and design is changing fundamentally. Low-cost airlines have become significant drivers of airport planning, along with aircraft size and other technical factors. They have different requirements than the "Legacy" carriers. They focus on cost and on alternative ways to handle passengers. Now being sizeable participants in the air transport industry, they are influencing airport design. They are central to the proliferation of secondary airports and metropolitan multi-airport systems. They are catalyzing the development of cheaper airport terminals configured internally much differently than traditional designs.
