Airports pour millions of dollars to improve wayfinding experience of the passengers. Most airports constructed back in 20th century are not designed to accommodate huge number of passengers at rush hours.

Airports can be stressful environments at the best of times. As well as dealing with potential queues, delays, crowds, and cancellations, passengers need to work out how to navigate an unfamiliar space and board their flight within a narrow time window.

These stresses, while universal to some extent, are magnified for those who don’t speak the local language. If you can’t make sense of the signage, it’s easy to get lost. And if you don’t understand the airport announcements, you may struggle when there’s a delay or change of gate. Flights delayed due to passengers arriving late at the gates can negatively impact the revenue of the airlines.
