However, the former concessionary, Infraero, experienced many legal and bureaucratic difficulties, which prevented most (if any) of these improvements from being completed on schedule. As of April 2013, the new concessionary unveiled a new expansion project, which included the new Terminal 3 (with a different design than the one proposed by Infraero), the widening of the main runway in order to enable operations by the new Airbus A380 and Boeing 747-8, and several other improvements in the existing terminals and parking area.
