The effects of the deregulation of airlines markets and the new technologies that have been introduced into air transportation have been heavily studied. Much of this analysis has been on the impacts on the industry and the immediate welfare implications for passengers and, to a lesser extent, cargo consignors. This study looks at the longer-term

From a planning perspective, a mega‐region can be defined as an extended network of metropolitan centers and their surrounding areas, crossing county and state lines, linked by integrated labor markets, land use systems and transportation and communication infrastructure. From a governance perspective, delimiting the jurisdictional borders of a mega‐region is rather challenging due to the overlap of hierarchy of governance systems. It has been suggested that the effective management of existing transportation infrastructure and the planning and financing of new investments in these areas will need to operate under a regional framework of governance. What such regional framework might look like is still subject to debate. Despite years in the planning, currently no mega‐regional transportation initiative has been implemented in the U.S. This article uses descriptive and interpretative analysis to further the debate in two areas. It first reviews definitional issues in the existing literature as they apply to mega‐regions and transportation. Second, it undertakes a comprehensive survey of regional initiatives, such as the Corridors of the Future Program, to highlight the complexity of multi‐state transportation projects. Lessons from this survey can be useful when developing future transport policy, as policymakers increase their efforts to adopt regional governance initiatives to finance transportation investments worldwide.

The increasing use of Internet booking facilities provides analysts with a rich data source of the profile of airline fares offered for a particular service as the time of departure approaches – "temporal-fares-offered curves." This paper offers a critical assessment of this form of analysis. It also reviews the empirical work that has been done using this type of data and synthesizes the information and insights that it can provide on the operations of an airline market. The subjects covered range from pricing strategies of low-cost and legacy carriers under different degrees of competition, to the extent to which there is price leadership in markets, and to ways in which airlines determine fares-offered when their schedules mean that their own services effectively compete with each other.
