In 2010, a city-owned cable provider was unable to pay the city of Burlington $17 million it owed. As a result, Moody's downrated the debt for the city. Moody's also downrated the credit rating for the airport, as well. Although voters approved a $21.5 million bond for airport expansion, this downgrade made borrowing the money too expensive. The airport therefore borrowed $7.5 million from the city for a $14.5 million garage expansion. In June 2011, the city asked for the money back. The airport was in the process of expanding the parking garage by adding two more levels on the north end. This would have given it a total of 2,700 parking spaces. This project was later completed in early 2012. The airport finished renovating the upper concourses bathrooms in late 2013.
