Neila83 - we operate with similar wx/turbulence conditions frequently, especially in the winter.
In the company I used to work for, regularly used to plan us along the jet stream within the turbulent area (inc ocl sevr) to make use of the tail wind & reduce the fuel burn. As there were often others there I guess we were not the only airline. Funny old thing s**d the pax save the money. I hated it but that is what you get when pax want the cheapest fare.
