In recent years, Pittsburgh International Airport (PIT) has become an airport to watch regarding the future of commercial aviation, as a modernization project to consolidate its terminals into a more centralized area of the airport is nearing its completion. Beginning in the late 2010s, this large-scale building project was originally scheduled for completion in 2023. However, with COVID-19 throwing a wrench into the renovation plans, the project is now set to be completed in the autumn of this year.
