A very convenient way to get to the city from the airport and back. It is much cheaper than a taxi…read moreor Uber and not much slower. You can only pay with certain credit cards, which is not ideal.
Note that this company (conexão aeroporto) operates two main lines, both to/from Confins (CNF) airport. One leaves from the location listed in the business details. This is a luxury bus that makes no stops. The other goes to/from the main bus station (Rodoviaria) on the north part of downtown, located on Avenida do Contorno. This bus makes a few stops (but doesn't take much longer) and is significantly cheaper (about 1/3 of the price).
The rodoviária is closer to where I live so that's the one I usually take. Never had any issues. The buses ave space for luggage.
