In 2017, it was considered by the company OAG the second best in punctuality in the world and first in Latin America, a position above that achieved in the previous year.

[citation needed] As part of the conclusions of these studies, because of their location, strategic importance, and security issues, new passenger facilities would be constructed in the areas of the Galeão Air Force Base in Rio de Janeiro and the São Paulo Air Force Base in São Paulo.

[citation needed] In relation to São Paulo, the initial planning of the airport involved three runways and four passenger terminals.

The new numbering reflects the order by which terminals are reached when one arrives at the airport by the access road, and is expected to be less confusing in the long term.

[29] On October 28, 2015, the National Civil Aviation Agency of Brazil (Anac) authorised Airbus A380 operations at Guarulhos Airport, effective four days later.

The Bonsucesso very high frequency omnidirectional range with distance measuring equipment (VOR-DME) is located 9.1 kilometres; 5.6 miles (4.9 nmi) to the east of GRU.

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 large Airbus A380 and Boeing 747-8, operated by Emirates and Lufthansa respectively, and several other improvements in the existing terminals and parking area.

[40] The American Airlines one is capable of performing line maintenance on two wide-body aircraft at the same time, of the types commonly used by the U.S. company on routes between São Paulo and the United States and the LATAM one is capable of performing line maintenance of one wide-body aircraft.

Taxi stands are located outside each of the two terminals on the Arrivals level; inside there are car rental agency representatives.

This service provides transportation connecting Guarulhos to Congonhas airport; to Tietê Bus Terminal; to Palmeiras-Barra Funda Intermodal Terminal, to Faria Lima Ave; To Republica Square (Praça da República); To Berrini Ave., Itaim Bibi district; and to the circuit of hotels along Paulista Avenue and Rua Augusta.

Gol Airlines and LATAM offer for their passengers free bus transfers between Guarulhos and Congonhas airports at regular times.

[60][61] Viação Cometa offers daily departures to and from the airport and the cities of Santos, Sorocaba, São Vicente, and Praia Grande.

Pássaro Marron offers bus services to São José dos Campos with departures every two hours.

Line 13-Jade of the São Paulo commuter rail system, operated by CPTM, connects with the airport through Aeroporto-Guarulhos Station.

[63] The line was opened initially on a trial phase and operates only on Saturdays and Sundays from 10 a.m. to 3 p.m., with trains every 30 minutes to the suburban station of Engenheiro Goulart in eastern São Paulo city, from where a further connection with CPTM's line 12 and at least another one by subway will be necessary to reach downtown and the main business areas.

The GRU Airport company reportedly vetoed a station closer to much busier Terminals 2 and 3 because it intended to build a shopping mall at the proposed location.

[66] The excessive number of train changes through crowded commuter rail and subway lines, and the added inconvenience of the requirement for a shuttle bus, has attracted criticism to the São Paulo state government, responsible for São Paulo's subway and commuter rail systems, which has been accused of flawed planning and overindulgence with the airport's private concessionaire.

[66] To solve this situation, Governor João Doria and State Secretary of Metropolitan Transports Alexandre Baldy proposed a people mover to connect the CPTM station directly to the airport, estimated to be opened in May 2021.

[69] In December 2020 it was announced that Brazilian firm Aerom, which owns the Aeromovel technology, had been selected to install the system.
