After going through immigration and security, check which terminal your flight is on the dashboard, if you need help identifying you can ask for help from the employee who is usually there. Then just go underground to take the train that will take you to the terminal. The airport is well signposted with signs telling you where to go. Good trip.
How lucky I happened to see your message. Hardly anyone would answer you since you asked in Portuguese on the American airport website. I suggest that next time ask in English to increase the changes of someone respond. Use Google translator if you need to. Well, just take the underground train and go to international terminal F. Good luck
