It’s a long way. Seriously. When you're sitting at O'Hare looking at a flight map, the distance from Chicago to Sao Paulo feels more like a transatlantic voyage than a quick hop down to the Southern Hemisphere. You are looking at over 5,000 miles. That’s roughly ten hours in a pressurized metal tube, depending on whether the jet stream is playing nice or acting like a bully.
Most people think they can just wing it. They book the cheapest ticket with a six-hour layover in Panama City or Miami and wonder why they feel like a zombie by the time they land at GRU. It’s a grind. But if you know how the routes actually work—and which airlines are secretly better for your back—the trip is actually pretty manageable.
The Reality of Flying Chicago to Sao Paulo
United Airlines owns this route. If you want a nonstop flight, they are basically your only option out of O’Hare (ORD). They run a daily service that usually leaves in the evening. This is the "holy grail" for business travelers because you sleep through the bulk of the flight and wake up in Brazil just as the sun is hitting the skyscrapers of Paulista Avenue.
The flight path is weirdly straight. You basically head south-southeast, crossing over the Caribbean and the vastness of the Amazon.
If you aren’t on that United nonstop, you’re looking at a connection. This is where people mess up. They see a cheap fare through American or Delta and jump on it without looking at the total travel time. Connecting through Miami (MIA) is the classic choice, but Miami International is a chaotic maze on a good day. If your layover is less than 90 minutes, you are asking for a panic attack.
A better "secret" move? Look at Copa Airlines through Panama City (PTY). Panama’s airport is basically a giant shopping mall where everyone speaks English, and the transit process is famously smooth. Plus, you’re breaking the trip into two roughly five-hour chunks, which is way easier on the legs than ten hours straight.
The Jet Lag Myth
Here is the good news: Chicago and Sao Paulo are usually only two or three hours apart, depending on daylight saving time shifts. In 2019, Brazil actually got rid of daylight saving time entirely. So, while your body might be tired from the flight, you won't deal with that soul-crushing jet lag you get when flying to Europe or Asia. You can basically hit the ground running.
Well, "running" is a relative term in Sao Paulo traffic.
Surviving Guarulhos (GRU) and the Arrival Chaos
When you finally land from Chicago to Sao Paulo, you’ll arrive at Aeroporto Internacional de Guarulhos. It’s huge. It’s also about 18 to 25 miles from the city center, which doesn't sound bad until you realize Sao Paulo has some of the worst traffic on the planet.

Don't take a random taxi from a guy whispering "taxi" in the terminal. Just don't.
- Uber is your best friend. It’s cheap in Brazil because the Real (BRL) is often weak against the Dollar.
- Guarucoop is the official airport taxi fleet. They have fixed prices, which is great because if you get stuck in two hours of traffic, you aren't watching a meter drain your bank account.
- The Airport Bus Service is actually surprisingly nice if you’re heading to the Tatuapé metro or certain hotel circuits.
The first thing you’ll notice stepping out of the airport is the humidity. Even if it’s winter in Chicago, Sao Paulo is likely hovering in the 70s or 80s. It’s a tropical metropolis, but it feels more like New York City on steroids than a beach town. If you were expecting palm trees and bikinis right at the gate, you’re in the wrong city; you want Rio for that. Sao Paulo is about concrete, world-class food, and a pace of life that makes Chicago’s Loop look sleepy.
Money and Connectivity
Don't change all your money at the airport. The rates are predatory. Use an ATM (Banco do Brasil or Bradesco are usually safe bets for international cards) to get some walking around money.
Honestly, most places in Sampa—that’s what the locals call it—take credit cards. Even the guy selling coconuts on the street likely has a "maquininha" (card reader). Just make sure your card has no foreign transaction fees.
Where to Stay: Forget the Airport Hotels
If you’ve just come from Chicago to Sao Paulo, you might be tempted to crash near the airport. Don’t. Guarulhos is a suburban industrial area. It’s boring.
Get into the city.
Jardins is the place if you want to feel fancy. It’s safe, walkable (by Sao Paulo standards), and filled with high-end boutiques. It’s basically the Gold Coast of Sao Paulo.
Vila Madalena is the move for anyone who likes a bit of grit and a lot of art. It’s the bohemian heart of the city, famous for "Beco do Aprendiz" and "Beco do Batman," which are alleys covered in world-class graffiti. If you want to drink a caipirinha while listening to live samba, this is where you go.

Itaim Bibi is the corporate hub. If you’re here on business—which, let's face it, many people flying from Chicago are—this is where the glass towers and the "Faria Limers" (the Brazilian equivalent of Wall Street types) hang out. The food here is incredible.
The Food Scene: Why Your Chicago Steaks Have Competition
Chicagoans are picky about meat. We have the stockyards history. We have Gibson's. But Sao Paulo is the only city that can actually give Chicago a run for its money in the steak department.
You have to go to a Churrascaria.
This isn't Fogo de Chão in Rosemont. This is the real deal. Places like Fogo de Chão (the original branches), Barbacoa, or Vento Haragano offer an endless parade of Picanha. Picanha is the "sirloin cap," and it is the king of Brazilian cuts. It has a thick layer of fat that melts into the meat. It’s life-changing.
But it’s not just beef. Sao Paulo has the largest Japanese population outside of Japan. The sushi in the Liberdade district is mind-blowing. It’s a weird, beautiful fusion. You’ll see Temaki (hand rolls) being sold like fast food, and they are better than almost anything you’ll find in the Midwest.
Navigating the Cultural Shift
People in Sao Paulo are warm, but they are "big city" warm. They are moving fast.
One thing that trips up Americans: the "thumbs up." In Brazil, a thumbs up (joinha) is the universal language for "thank you," "you're welcome," "okay," or "I understand." You will see people doing it constantly.
Also, get used to the noise. Sao Paulo is loud. Helicopters are everywhere—it actually has one of the highest densities of private helicopters in the world because the rich would rather fly over the traffic than sit in it.

Safety is Nuanced
Is it safe? This is the question everyone asks before flying Chicago to Sao Paulo.
It’s not as dangerous as the "doom-scrolling" news makes it out to be, but it’s not Naperville either. You have to be "city smart."
- Don't walk around with your phone out. This is the number one way people get robbed. "Bike thieves" are common; they snatch the phone right out of your hand and pedal away before you can blink.
- Use Uber at night. Even if it’s only four blocks.
- Keep your jewelry simple. Leave the Rolex in the Chicago safe.
Logistics for the Return Trip
Heading back to O’Hare is usually a night flight as well. Most flights leave GRU between 8:00 PM and 11:00 PM.
Give yourself at least four hours to get to the airport. I’m not joking. The Dutra highway, which connects the city to the airport, can turn into a parking lot at any moment. There have been stories of people missing flights because a single truck broke down three miles away.
The United lounge in Terminal 3 is actually quite good if you have access. It’s a great place to shower and change before that long haul back to the 312.
Essential Packing List for the 10-Hour Flight
Don't just pack for the destination; pack for the journey. The air on those 787 Dreamliners or 777s is incredibly dry.
- A heavy-duty moisturizer. Your skin will thank you.
- Noise-canceling headphones. Essential for blocking out the engine hum and the inevitable crying baby.
- Compression socks. For a ten-hour flight, these aren't just for old people; they prevent your ankles from turning into balloons.
- A universal power adapter. Brazil uses a unique "Type N" plug (three pins in a flat triangle), though many modern hotels have universal outlets.
Making the Most of the Connection
If you find yourself with a long layover in a city like Bogota or Panama City on your way down, don't just sit at the gate. If you have more than six hours in Panama City, you can actually take a quick Uber to see the Miraflores Locks at the Canal. It beats staring at a departure board.
Actionable Steps for Your Trip
To make this journey work, you need a plan that starts before you even buy the ticket.
- Check your Visa status. For US citizens, the visa requirements for Brazil have been in a state of flux. As of 2025/2026, always check the official Brazilian Consulate website because the e-visa requirement was recently reinstated after a period of being waived. Don't get turned away at O'Hare because you forgot a piece of digital paper.
- Book the "extra legroom" seats early. On the United nonstop, the "Economy Plus" section fills up fast. Those extra few inches are the difference between sleeping and spending ten hours staring at the seatback in front of you.
- Download WhatsApp. Everyone in Brazil uses it. You will use it to talk to your Uber driver, make restaurant reservations, and even message your hotel. If you don't have it, you're invisible.
- Notify your bank. Brazilian ATMs are notorious for triggering fraud alerts. Let them know you’ll be in Sao Paulo so you aren't stuck without cash at 6:00 AM.
- Learn five words in Portuguese. "Obrigado" (thank you), "Por favor" (please), and "Bom dia" (good morning) go a very long way. Most Paulistanos speak some English, but showing effort changes the vibe of every interaction.
