Air and wind over the Atlantic is usually calm, providing some of the least turbulent routes. However, if flying in certain areas such as near the equator or north near the jetstream, you may encounter turbulence. However, this turbulence is usually predictable and so avoidable by the pilots.

Transatlantic flights are known for experiencing turbulence, primarily due to the Jet Stream, a high-altitude "river" of fast-moving air that flows from west to east across the Atlantic Ocean. When planes fly through or near the edges of these wind currents, they often encounter "Clear Air Turbulence," which is invisible to the eye and radar but causes the characteristic "bumps" felt in the cabin. Pilots typically attempt to utilize the jet stream when flying toward Europe to save time and fuel, while trying to avoid it when flying toward North America. While the frequency of turbulence has increased due to climate change, it is important to remember that it poses no structural danger to modern aircraft, which are designed to withstand forces far greater than those encountered in flight. For the smoothest ride, many travelers choose to fly in larger wide-body aircraft like the Boeing 787 or Airbus A350, which handle rough air more gracefully, and they always keep their seatbelts fastened even when the sign is off.
