Look, Guarulhos Airport is crawling with taxi vultures who'll charge you R$250+ for what should be a R$60 ride. The Uber mafia situation isn't much better — They've got the airport sewn up tighter than a politician's expense account. Don't be another tourist sucker.

Take the official Airport Bus Service (Express Airport Bus) from Terminal 2 or 3 to Tietê Bus Terminal. It's R$45, runs every 30-45 minutes from 5:30 AM to midnight, and it's comfortable with air conditioning and WiFi. Journey takes 45-60 minutes depending on traffic. From Tietê, you've got access to the entire metro and CPTM train network for R$4.40 per ride.

Yes, it takes longer than a taxi. Yes, you might have to stand on the metro with your luggage. But you'll save R$200+ that's better spent on actual food and experiences instead of lining some scammer's pocket. That's four excellent meals at proper restaurants, or a week of metro passes, or entry to three museums.

Pro tip from someone who's done this route 50+ times: if you're staying in Vila Madalena, Pinheiros, or anywhere on the Green Line, take the bus to Tietê, then CPTM Line 11-Coral to Luz station, transfer to Metro Blue Line to Santa Cecília, then Green Line to your destination. Sounds complicated but it's actually faster than fighting downtown traffic.
