Powerful Atlantic Jet Stream Accelerates Eastbound Flights, Cutting Travel Times by up to an Hour

Jet stream advantages include faster arrival times for eastbound flights, but potential downsides involve turbulence and delays on the ground upon early arrival.

• The Atlantic Jet Stream, blowing from west to east, has accelerated certain transatlantic flights, reducing their travel times by up to an hour, with some planes reaching speeds of up to 778 mph.
• This phenomenon has been particularly beneficial for flights traveling from the United States and Canada to Europe and further east, with several airlines such as British Airways, United, and Emirates reporting significantly early landing times.
• The jet stream is a band of strong winds that behaves similar to a fluid, with its currents capable of pushing along a plane at a faster speed, likening a boat being pushed by a strong water current.
• While an accelerated speed can lead to early arrivals, not all effects of the jet stream are positive. There are potential downsides including flight turbulence and possible ground delays at the arrival airport if a gate is not available for an early arrival.
• The jet stream's impact is also directional. While it accelerates eastbound flights, flights traveling west, like from London to New York, can be slowed down by the same phenomena, akin to a boat battling a strong upstream current.
