> but I think, at least with Dulles Airport's design, it mostly failed because it was completely incompatible with a single-point bottleneck security line (sadly) required at modern airports. MCI (Kansas City) has separate security areas for each handful of gates. Here's a map showing the general shape of one of the three terminals: https://www.ifly.com/kansas-city-international-airport/MCI-Concourse-A https://www.ifly.com/kansas-city-international-airport/MCI-C... I don't see an online map with the security areas marked, but the way it works is that the outer edge is divided into segments for each few gates, and each segment is separate with its own security. . For a "mobile lounge" setup, I'd assume each docking area for the lounges would have a security entrance and it ought to work about as well as what MCI has.
