Just like the seasonal decoration we got last December to pretty up the airports, we could have the mainstay of guiding people to where they need to go with rope/ribbon barriers.
Why it should be implemented:
To the flow and guide PAX around the terminal, to separate Arrival and Departing, to build queues where we currently cannot. To enhance the current queue barriers to allow more flexibility. Secure other areas off from others etc. Endless uses.
