70 Airport Passenger Terminal Planning and Design Figure 85. Passengers and bags at Baggage Claim model. Figure 84 illustrates a typical primary inspection area with the standard dimensions as pub- lished by CBP. Baggage Claim Following the primary processing step, the passengers move to baggage claim to retrieve their checked bags. Because of delays that may occur during primary processing, checked bags are often at the claim unit before the passengers arrive. In Figure 85, the next section in the model uses a probability bag-matching model to estimate the time a claim unit will be in use and how much linear frontage will be required for a specific demand load. The user must input average or specific information in relation to passengers and bags, as well as the likely bag delivery (dump) rate and delays. From these inputs the included bag-match model will estimate the desired outputs and generate a graph to show a possible flow pattern for the passengers and bags. The key outputs are also highlighted on the graph in Figure 86. Figure 86. Chart of passengers and bags at baggage claim.

Federal Inspection Services/U.S. Customs and Border Protection Model 71 After primary inspection, passengers proceed to international baggage claim. The approach in sizing baggage claim for an FIS is similar to that for a domestic baggage claim. However, the time a claim unit is in use is typically longer for two reasons: Checked baggage ratios and the percentage of passengers with checked bags are typically higher than for domestic flights, thus requiring more time to unload. All passengers entering the United States must also have CBP baggage inspection at their first point of entry (except those in-transit). Connecting passengers then re-check bags to their final destination. Passengers must clear CBP primary before entering the baggage claim area, which normally allows bags to accumulate on the claim unit before passengers arrive. This delay can require a claim unit with greater capacity for baggage storage than is required for domestic flights with similar passenger characteristics. Thus, an international claim unit may be sized more for bag- gage storage than for active claim frontage, although both aspects should be considered. If suf- ficient storage isn't available (or passengers are delayed at CBP primary longer than anticipated), airline employees may have to unload bags from the claim unit and place them on the floor for passengers to pick up.
