JFK Airtrain (2003)
JFK International Airport opened its automated Airtrain in December 2003, connecting terminals and replacing shuttle buses. The new system reduced the need for some ground transportation staff while creating new jobs for station attendants and maintenance workers.
Some shuttle drivers were laid off, but airport authorities hired new staff to operate and maintain the train.
The Airtrain became a model for other U.S. airports, demonstrating that automation can shift job composition over time.
LAX's SkyLink is a similar automated people mover replacing human-operated shuttles, causing a temporary job reduction before new roles emerge.
