Of these on-board passengers, many are flying to Denver as their final destination. Because
Denver functions as a hub for United and Frontier, however, a significant fraction will connect
through DEN to points beyond. These connecting passengers may make expenditures in the
terminal, as was assumed in Section I: Direct Impact. However, they will not contribute to
visitor expenditures in the Denver area and so are removed from consideration of the indirect
economic impact.
The percentage of international traffic connecting through Denver was determined with on-board
international passenger information, as well as itinerary-level origin-and-destination passenger
data. The analysis showed that on-board traffic from Mexico had the lowest connecting
percentage at Denver. Only 15% of on-board passengers from Mexico were connecting through
Denver, while 85% ended their journey there. 20% of traffic from Europe connected through
Denver, while 80% was local or non-connecting.
Because there is currently no passenger traffic coming directly from Asia to Denver, a
connecting percentage had to be estimated by comparing Denver to San Francisco, another
United hub that has a similar annual passenger volume. SFO’s connecting percentage of Asian
traffic was 45%, a plurality of which was bound for Las Vegas. Denver’s connecting percentage
of Asian traffic was estimated to be 30%, somewhat lower than SFO. Asian traffic will prefer
not to connect to Las Vegas through Denver, which require back-hauling. With 30% connecting
traffic, the local percentage of on-board traffic is therefore 70%.

O&D Psgrs
Of these passengers ending their journey at Denver, a portion represents Denver residents
returning from abroad, and the rest consists of visitors to the area. Only the visitors contribute to
visitor spending and the indirect economic impact of the new daily flight. Travel ‘directionality,’
that is, the percentage of Denver residents versus visitors among the Denver O&D passengers,
was calculated with point of sale information from the US DOT’s O&D passenger ticket survey.
With this data it is possible to determine the airport at which roundtrip passengers began their
journeys.
Among O&D passengers between Denver and Mexico in 2000, only 24% were found to be
Mexican visitors to Denver, while 76% were Denver residents visiting Mexico. The O&D travel
between Denver and Europe was more balanced, with 48% originating in Denver and 52% in
Europe. O&D travel between DEN and Asia was weighed toward visitors, with 39% Denver
residents and 61% Asian visitors.

Applying these directional percentages to estimated DEN O&D traffic yields the visitor figures
shown in Figure 14. Figure 15 below recapitulates the calculation of estimated annual visitors to
Denver brought by additional flights from Mexico, Europe, and Asia.
