This books provides a fresh and innovative analysis of the evolving space-time structures of global air travel and city accessibility in the information age. The book focuses on the massive consumer/business market for air travel, its airlines, airports, and the global airline network. The authors utilize a suite of novel data sources that include flight itinerary costs, flight duration, distance traveled, connections made, segments flown and a massive database of origin-destination paths for virtually every airline in the global network. It is likely that the information to be used in this study represents the most comprehensive air travel database ever assembled outside the private sector. This book examines the fundamental factors beyond physical distance that shape the global airline network in the information age. This includes a comprehensive look at the role of deregulation in the airline industry, terrorism, and the impact of low-cost carriers on competition and airline pricing structures.
