This thesis presents an analysis of signage inside two international airports, public linguistic spaces that should be accessible to both global visitors as well as disabled populations. International airports and their multimodal signage present a rich environment to study global hierarchies and values. The general research question that guides this exploratory case study is: how does signage at two large international airports reflect social hierarchies in these culturally diverse spaces? More specifically, an analysis is presented of the signage visible in airport walkthrough videos of Denver International and the new Beijing Daxing International airport. This thesis found that English was a dominant language on signage in both airports, and that communicative elements such as pictographs and building architecture reflected both local and international values within the spaces.
