What to Expect

Your flight from Syracuse to Anchorage is a long one, and it does cross several areas known for turbulence. Shortly after takeoff, you might encounter some mechanical turbulence as you fly over the Northern Appalachians. This happens when wind hits the mountains and creates choppy air. As you continue northwest, you'll cross the Great Lakes, which can cause lake-effect turbulence, especially when cold air moves over the warmer lake waters. Finally, as you approach the Atlantic seaboard, expect the possibility of clear-air turbulence, or CAT, which is caused by shifting air currents at high altitudes. It’s worth remembering that pilots are very familiar with these patterns, and they constantly monitor weather conditions to navigate the safest and most comfortable route possible. These are not unexpected events, but normal atmospheric conditions that are accounted for.

Between Syracuse and Anchorage, the route crosses the Northern Appalachians from Pennsylvania through New England. While lower than western ranges, the Appalachians still produce mechanical turbulence and low-level wind shear, particularly when strong northwest winds follow cold frontal passages. Flights below 20,000 feet feel this most acutely.

Turbulence Factors on This Route

• Mechanical Turbulence: The Northern Appalachians generate low-level mechanical turbulence during strong post-frontal northwest winds.
• Lake-Effect Turbulence: The Great Lakes produce lake-effect convection and low-level wind shear from land-water temperature contrasts.
• Clear-Air Turbulence (CAT): The Atlantic coast jet stream and land-sea temperature contrasts create frequent clear-air turbulence at cruising altitude.

When Is This Route Bumpiest?

For the smoothest possible flight, aim to travel during the summer or early fall. The weather is generally more stable during these months, minimizing both lake-effect and mechanical turbulence. Winter, late fall, and early winter can be a bit bumpier. This is when the temperature differences around the Great Lakes are most pronounced, leading to increased lake-effect turbulence. Also, the jet stream tends to be stronger and more erratic in the colder months, contributing to a higher chance of clear-air turbulence near the Atlantic seaboard.

Tips for This Flight

If possible, consider booking a morning flight; the atmosphere tends to be more stable earlier in the day. Any turbulence you do experience on this route is most likely to feel like driving on a slightly bumpy road, or perhaps a boat gently rocking on the water. Focus on your breathing to stay relaxed. A window seat can sometimes make things feel less turbulent since you have a visual reference point outside, but an aisle seat gives you more room to stretch your legs. Remember, the crew is well-trained to handle these situations, and they’re there to help you feel comfortable and safe.
