. Results Passenger time spent queuing for and proceeding through CBP Primary processes versus the unload time and transportation time to baggage claim dictate whether bags or passengers are ready at the baggage claim carousel.

may proceed directly from CBP Primary to the exit point and will typically avoid the congestion caused by passengers leaving the FIS area with bags. For bag timing from flight arrival to bags ready at sortation, there is also a significant reduction in time for international-to-international connection passengers versus passengers making Figure E-4.

. It appears that the baggage claim process adds a significant amount of time for both passengers in the FIS area and bags to be ready for sortation.

Note that the airline's upstream operations prioritize the international-to-international connection bags so that they are available to be unloaded first and can be inducted into the hub airport's baggage handling before terminating or domestic connecting bags. If internationalto-domestic baggage recheck can be eliminated, bags can similarly be prioritized but would represent a significantly larger volume of bags for the airport and airline to facilitate.

Table E-1 lists risk items that were tested through the bag screening equipment. Simulated contraband or illegal items were approximated with suitable replacements.

Results Of the 84 bags, 26 had substances representing illegal or contraband items placed in them. The remaining 58 bags had no contents presenting an issue to CBP clearance.

. The test team concluded, however, that the review of TSA EDS screening images provides a far superior risk management tool for CBP when compared to the current domestic connections process of viewing the exterior of passenger bags at the Egress Point from the FIS area.

Checked baggage participating in the program will be unloaded from the aircraft and held at the ramp level on an unused carousel for possible delivery to the FIS Hall for CBP Secondary Processing. • Bag process: After a predetermined amount of time, if bags are not requested for retrieval by CBP, they may be transported by Alaska/Horizon ground handlers to the Main terminal to be inducted back into the baggage handling system using the same process as Preclearance connecting bags.

on the same trip from the South Satellite to the Main Terminal • The possibility that bags might be transported to the Main Terminal before passengers are processed through CBP Primary or Egress during times of severe congestion and long wait times in the FIS Hall • Resource requirement to physically deliver bags to CBP Secondary • Congestion for one elevator used for oversize bag route (and personnel movement to/from ramp level to the South Satellite terminal) • Cooperation, training, and action required from participating airlines (i.e., informing passengers and marking bags as connections from origin airport)

is possible and would result in relatively larger gains for air carriers, whereas airports with low minimum connection times would only allow for minor reductions in MCT and smaller benefits to airlines. Simulation Modeling Discrete-event simulation models are useful for evaluating scenarios in which the results are driven by time-dependent interactions of events.

• Wait times at baggage claim Several scenarios were conducted using the simulation; the results are shown in Table E-5. Relevance to Eliminating/Reducing Baggage Recheck While the simulation model provided results of predicted passenger and bag times under each scenario, the specific times themselves are specific to a particular facility and its configuration.

The storage area might be used before bag rescreening or after rescreening and after bag sortation. In terms of an overall decision whether to implement baggage recheck for either international or domestic connections, the simulation model results indicate that a small percentage of connecting passengers not required to recheck bags generally provides greater time benefits.
