Authorities arrested 36-year-old Aditya Singh after he had spent three months living in the secure side of Chicago's O'Hare international airport, relying on the kindness of strangers for food, sleeping in terminals and using the bathroom facilities. He was caught by an airport employee asking for his ID. Singh is one of many individuals residing in terminals for weeks, months or years. Since 2018 there has been a rise in the number of homeless people in large airports. Officials try to provide aid and crisis intervention teams to connect homeless people to housing and other services. But most would prefer a solution where airports no longer operated as homeless shelters.
