Super-Fast Jet Makes Jets To Europe Super-Fast
Posted by Dan Satterfield

Wind flow at 250 millibars pressure level (around 3000 meters,) where jet aircraft cruise) shows a jet stream of around 150 knots over the Atlantic Thursday morning. Click for large version.
Departures were being delayed from the U.S. to the UK to keep aircraft from arriving to early in Europe. You have to feel for the folks flying from Heathrow to Seattle though; add two hours to an already LONG flight! I experienced this once on a flight from Atlanta to London, and arrived an hour early. We sat on the plane though waiting for a gate to open up!
