The best regional airport from Brazil but it’s very expensive to eat or to buy things there. Ah another good tip DON’T FORGET to arrive early coz it’s really busy all time.
To get to the subway: Go down to the taxi stalls at arrival, cross the lane and walk 60m to the right to the last bus stop. Look for the sign 609J/10. It's the bus that goes to the Sao Judas Station.
