DEN took a major leap forward building an iconic hotel plus the addition of the Train to the Plane service but still operates with a dysfunctional outdated terminal. In 22 years technology has driven a change in the processing of passengers through ticketing and security. DEN should be applauded for forward thinking on searching for innovation on the best practices for all the unused space (much of the space on level 6 sits unused because of ticketing kiosk and common use counters). The true leaders in the aviation industry such as DFW, ATL, Schiphol & Changi are all embracing innovation, growth and change.
