Where can I find the planned and flown paths for certain flight routes?

Are there official definitions of air traffic corridor pathing? Specifically European & Mediterranean routes.

I'm working on an application that needs this input data to perform an analysis. I and others in my company have been unable to find anything, and I really don't want to have to derive something approximating it myself if I don't have to.

Edit: Since what I'm asking for doesn't seem to be very clear I'll try a different way.

When an commercial jet starts a flight from one airport to another. I assume it had a generally predetermined path (or options of paths). These are not straight shortest path between two points on an ellipsoid so the data at OpenFlights.org isn't helpful, as it is not accurate enough. Obviously though no one can fully predict exactly where an aircraft will be in the future because that changes in respect to many different unknown variables, but I need something more like this, which was done tracking one commercial jet from one airport to another which includes no amount of variation, and it takes a long time to do this live.

Ideally I could get the general routes that these individual flights tend to follow, but to get an approximation of the actual routes between airports would be a whole lot better than I am know.

In a perfect world there would be lat/lon/alt/ pairings of the paths with some sort of standard deviation on those points. I doubt that exists but anything that could get me closer to that would be excellent.

Paying for something is not necessarily a problem, as long as I can prove it to my boss that it is what we need.

• Are there official definitions of air traffic corridor pathing please try to rephrase this. Are you asking if there are defined paths (routes)? Commented Apr 29, 2016 at 18:26
• What do you need it for? Perhaps if you explained, it would shed some light on what you actually need. Commented Apr 29, 2016 at 18:54
• There are airways (that is the term you should probably be searching for) defined, but they are not always used. Commented Apr 29, 2016 at 18:55
• Here are charts of airways for Eurocontrol. With the availability of GPS navigation aircraft can now fly more direct routes so fewer aircraft are using airways for navigation. Commented Apr 29, 2016 at 19:29
• Just an update: Navigraph told me their data is only for non-professional fligh simulation use and directed me to their supplier Jeppesen, Inc. They also noted a site called skyvector.com which definitely has the data, but I haven't had time to see if I could extract it from there yet. Commented May 13, 2016 at 16:22
