Despite its modest size, Araguaina Airport offers passengers the necessary amenities for a comfortable journey. Following modernisation in 2013, the terminal was equipped with modern security systems, check-in counters, and a baggage reclaim belt. Currently, the airport is undergoing a new phase of large-scale renovation under the federal AmpliAR programme, aimed at developing regional aviation. Work is underway to install new navigation equipment, expand the terminal to 2,000 sq. metres, improve the runway, and attract flights using larger aircraft, promising to make the air harbour even more modern and convenient for passengers. The terminal building houses a cafeteria and car rental agency desks, and thanks to its close proximity to the city, you can reach the centre in just 15-20 minutes by taxi or city bus.
