We analysed more than 15,000 data points along your exact route so you know exactly what to expect today. You are flying from Logan International, Boston to Guarulhos - Governador André Franco Montoro International Airport, São Paulo and the overall conditions look mostly smooth.

There are a couple of short sections with bumps, but nothing out of the ordinary. Turbulence can feel uncomfortable, but it is not dangerous. Aircraft are designed to handle it easily, and pilots deal with it every day.

What to expect during the flight
Around 1 hour into the flight, there may be a bit more intense turbulence. Around 5 hours 30 minutes into the flight, there may be a bit more intense turbulence. The crew may adjust altitude to keep things comfortable. Aside from these brief moments, you can relax and enjoy the rest of the flight.

Takeoff and landing
Takeoff should feel smooth with possible light bumps, with calm conditions around the airport. Landing should feel smooth with possible light bumps with typical approach conditions.

Your journey
Shortly after takeoff, you'll be crossing the Appalachian Mountains. Shortly after takeoff, you'll be flying out over the ocean. About 5 hours and 24 minutes into the flight, you'll reach the coast of Suriname. About 6 hours into the flight, you'll be flying over Brazil. If the skies are clear, you might catch some beautiful views from your window.

Winds aloft
Winds at cruising altitude are about 42 knots. These winds are favorable and may get you there up to 12 minutes early.

If you feel nervous at any point, remember that turbulence is expected, safe, and part of normal flying. The crew is monitoring everything, and the aircraft is built to handle far more than anything you will feel.

Have a safe and calm flight.
