📊 900 data points analyzed HIGH Confidence
Your Flight

We analysed more than 900 data points along your route from Logan International, Boston to Montreal / Pierre Elliott Trudeau International Airport, Montréal.

Your Journey Beta

Your route takes you over the Appalachian Mountains – conditions there can sometimes cause light turbulence.

Smooth Flight

We're expecting smooth conditions throughout your flight. You can sit back and relax.

Takeoff

Takeoff should feel smooth with possible light bumps, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 80 knots.

Landing

Landing should feel smooth with possible light bumps with typical approach conditions.

You're in Safe Hands

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.

🌤️ Afternoon Flight

Afternoon flights may encounter more turbulence due to thermal activity as the sun heats the ground, creating rising air currents.

Regional Jet (Small)

Regional jets are smaller and lighter, so turbulence may be more noticeable to passengers. However, they are fully certified and safe for all weather conditions.
