Airports are struggling to keep up with record-setting increases in air traffic, with new projects at major hubs aiming to bring outdated infrastructure up to speed.

The number of people getting on flights increased from 689 million in 2008 to 880 million in 2018, a 27% jump. The U.S. has not constructed a new major airport since 1995. A lot has changed since 1995, including increased and enhanced screening and the creation of the Transportation Security Administration.
