Hubli airport is spread over 369 Acres and has one runway oriented 08/26, 1,670 metres in length. Its apron measures 13,500 square metres while its terminal building measures 368 square feet and can handle 150 passengers. The airport has basic Air Navigation and landing aids like PAPI and a NDB.
The Government of Karnataka signed a Memorandum of Understanding (MoU) with the Airport Authority of India (AAI) in January 2013 to develop Hubli Airport. The AAI will expand it into an all-weather airport at a cost of Rs 1.60 billion. 530 acres (2.1 km2) of agricultural land was acquired by the State Government and handed over to the AAI. The area of the airfield will be increased to 615 acres and the runway will be extended to 7,500 feet. The runway extension work is expected to cost Rs 900 million. A new taxiway, roofing, fire station and a domestic terminal building are also part of the up gradation project that will enable the operation of larger aircraft like the Boeing 737 and the Airbus A-320. The terminal building will be expanded to cater to 300 passengers. A Doppler Very High Frequency Omnidirectional Range (DVOR) will also be installed. The project is expected to be completed by 2014.
On 9th March 2015, A Spicejet Bombardier Dash 8, operating flight SG-1085 from Bangalore with 74 passengers and 4 crew, landed on Hubli's runway in heavy rain, veered off the runway and came to a halt on soft ground with the left main gear collapsed. There were no injuries but the aircraft received substantial damage to left hand main landing gear, propeller and engine.
