Hartsfield-Jackson International will soon start work on a $6 billion expansion and makeover that will update the domestic terminal and concourses, introduce new features like a hotel and eventually add another concourse and runway to the world's busiest airport.

It’s part of a 20-year plan aimed at maintaining Hartsfield-Jackson’s status as a leading airport, replacing aging facilities and enabling growth.

It won’t be easy on travelers. The plan entails a series of construction projects in different areas of the airport, which could change traffic patterns both inside and out.
