First of all let me just say that I am very glad for this forum. All of you people out here answering all these questions is just wonderful. I for one am very grateful.

Ok, on with my question.
Listening to ATC on my scanner, I sometimes here this: NWA 353 climb and maintain 17,000 and join J21. What is J21? I have heard some people say it has to do with the jet stream. If that is the case, can someone be a little more discriptive about what that means? Thank you in advance.

Minneapolis, MN

a Jet Route... it's a high altitude airway.

They are plotted on high altitude enroute charts for use between FL180 and FL450 and are usually defined using radials between HIGH class VOR's.

Three NOAA high-altitude charts cover the US; they cost $4.10 apiece. You can see a sample (of the Chicago area) at http://acc.nos.noaa.gov/Catalog/EnrouteHigh.html

J21 runs from the Duluth VOR to Gopher to Omaha and on down to Laredo, or maybe beyond.
