A municipal authority that oversees Pittsburgh International Airport is considering downsizing the facility, which has seen significantly less passenger traffic since US Airways closed its hub there in 2004.
Allegheny County Airport Authority officials say they're considering reducing the number of gates and better promoting the area's economy, culture and innovation.
The authority is considering demolishing parts of the concourses.
Officials say the authority is working on a master plan that should be completed next year.
The airport underwent a $1 billion expansion in the early 1990s. It is designed to serve 35 million passengers annually, but currently serves about 8 million people a year.
Officials say the airport regularly uses only about half of its 75 gates.
