Following the authors’ previous research on real-time intermodalism, this study proposes a Regional Ground Delay Program (Regional GDP) concept into the Collaborative Decision Making (CDM) system when a hub airport located in a regional airport system encounters a severe airside capacity reduction. It suggests that air traffic flow managers evaluate not only the imbalance of traffic demand and terminal capacity at the hub airport but also excess capacity at other airports in the same region, assuming that airlines could incorporate ground modes into their disruption management and use ground vehicles to transport passengers and crew members between original scheduled and diverted airports. A mathematical programming model is established to help air traffic flow managers make decisions on initiating a Regional GDP advisory. A case study at San Francisco International Airport (SFO) was conducted. Results show that the initiation of a Regional GDP is suggested on a day with severe weather conditions.
