This synthesis study is intended to inform airport operators, stakeholders, and policy makers about common use technology that enables an airport operator to take space that has previously been exclusive to a single airline and make it available for use by multiple airlines and their passengers. Common use is a fundamental shift in the philosophy of airport space utilization. It allows the airport operator to use existing space more efficiently, thus increasing the capacity of the airport without constructing new gates, concourses, terminals, or check-in counters. This synthesis was prepared to help airport operators, airlines, and other interested parties gain an understanding of the progressive path of implementing common use, noted as the common use continuum. It identifies advantages and disadvantages to airports and airlines, and touches on the effects of common use on the passenger. The information for the synthesis was gathered through a search of existing literature, results from surveys sent to airport operators and airlines, and through interviews conducted with airport operators and airlines.

The aviation industry has seen dramatic changes in the past two decades with significant growth during the 1990s; a significant industry disruptive event on September 11, 2001; and an economic decline resulting in a sharp rise in fuel prices that has substantially changed the economics of airline operations and a decline in growth. During this period, airlines have adapted to the changes in various ways, many of which have resulted in adaptability issues for airport operators, thus raising the question of "is there a better way" to be more flexible and responsive to airline service changes in good and bad times. From an airline perspective, cost reduction since September 11 has been a prominent focus. From an airport operator perspective, adapting to and accommodating changing flight services by incumbent carriers as well as new entrant services has been a key focus. In recent years, offering more cost-effective solutions to retain or encourage new services in the face of service reductions has become a key focus. Airport operator interests in common use have been heightened by the potential for achieving a reasonable balance between airline and airport operator interests. The implications of transitioning from a traditional model (of airline facility use and leasing focused on dedicated facilities) to common use has elicited varying and, often, conflicting perceptions of benefit and cost.

TRB's Airport Cooperative Research Program (ACRP) Report 25, Airport Passenger Terminal Planning and Design comprises a guidebook, spreadsheet models, and a user's guide in two volumes and a CD-ROM intended to provide guidance in planning and developing airport passenger terminals and to assist users in analyzing common issues related to airport terminal planning and design. Volume 1 of ACRP Report 25 explores the passenger terminal planning process and provides, in a single reference document, the important criteria and requirements needed to help address emerging trends and develop potential solutions for airport passenger terminals. Volume 1 addresses the airside, terminal building, and landside components of the terminal complex. Volume 2 of ACRP Report 25 consists of a CD-ROM containing 11 spreadsheet models, which include practical learning exercises and several airport-specific sample data sets to assist users in determining appropriate model inputs for their situations, and a user's guide to assist the user in the correct use of each model. The models on the CD-ROM include such aspects of terminal planning as design hour determination, gate demand, check-in and passenger and baggage screening, which require complex analyses to support planning decisions. The CD-ROM is also available for download from TRB's website as an ISO image.

This report provides a guidebook on how to develop air traffic forecasts in the face of a broad range of uncertainties. It is targeted at airport operators, planners, designers, and other stakeholders involved in planning, managing, and financing of airports, and it provides a systems analysis methodology that augments standard master planning and strategic planning approaches. This methodology includes a set of tools for improving the understanding and application of risk and uncertainty in air traffic forecasts as well as for increasing overall effectiveness of airport planning and decision making. In developing the guidebook, the research team studied existing methods used in traditional master planning as well as methods that directly address risk and uncertainty, and based on that fundamental research, they created a straightforward and transparent systems analysis methodology for expanding and improving traditional planning practices, applicable through a wide range of airport sizes. The methods presented were tested through a series of case study applications that also helped to identify additional opportunities for future research and long-term enhancements.

"TRB's Airport Cooperative Research Program (ACRP) Report 10: Innovations for Airport Terminal Facilities explores worldwide developments in airport landside facilities design, and examines future trends and innovative passenger service/processing concepts. View information about the TRB webinar on ACRP Report 10:Innovations for Airport Terminal Facilities, which was held on Monday, April 26, 2010"--Publisher's description.

TRB's Airport Cooperative Research Program (ACRP) Report 41: Guide to the Decision-Making Tool for Evaluating Passenger Self-Tagging provides the information and tools, included on and accompanying CD-ROM, necessary for an airport or airline to determine the appropriateness of pursuing passenger self-tagging should it be allowed in the United States in the future. The tools, in an Excel Spreadsheet format, allow for the input of airport-specific information, such as facility size and passenger flows, while also providing industry averages to assist those airports and airlines that haven't yet collected their individual information. The decision-making tools provide both qualitative and quantitative information that can then be used to assess if passenger self-tagging meets organizational needs or fits into their strategic plan. Appendix A to ACRP 41 was published online as ACRP Web-Only Document 10: Appendix A: Research Documentation for ACRP Report 41. The CD-ROM included as part of ACRP Report 41 is also available for download from TRB's website as an ISO image.

Air Transport: A Tourism Perspective provides rigorous insights into the current complexities, synergies and conflicts within air transportation and tourism, presenting a balanced, comprehensive, contemporary, and global analysis that thoroughly examines the links between theory and practice. The book offers readers a multi-sector, global perspective on the practical implications of the link between air transport and tourism. By using a novel approach, it systematically explores the successive stages of a tourist's trip-investigating reasons for flying, the airport experience, airline industry structures, competition and regulation, and air transportation and destination interrelationships. In addition, the book explores current and salient debates on such issues as the influence of traveling to visit friends and family, the role of charters versus low cost carriers, public subsidies to support airport development, and much more.

TRB's Airport Cooperative Research Program (ACRP) Report 33: Guidebook for Developing and Managing Airport Contracts is a guidebook of best practices for developing, soliciting, and managing airport agreements and contracts for use by a variety of airports. The agreements referenced in this guidebook range from airline-related agreements to communication and utility service as well as common-use, ground transportation, and concessions agreements for a variety of passenger services. An accompanying CD-ROM provides sample agreements in each of these areas. The CD-ROM included as part of ACRP Report 33 is also available for download from TRB's website as an ISO image. Links to the ISO image and instructions for burning a CD-ROM from an ISO image are provided.
