Tough economic conditions for airlines at the start of the 21st century, the September 11 attacks, and high operating costs at the airport put the US Airways hub in Pittsburgh at a serious disadvantage. By 2003, US Airways reported to be running a $40 million loss per year ($ present day dollars) operating its hub at Pittsburgh, while also paying roughly 80% of the new airport's $673 million debt ($ present day dollars) stemming from its requested construction of the new terminals.
