RR, I sympathise with your problem. The problem is that what appears on our flight plans is not always what the controller has in front of him/her as the filed level. Some controllers in the Swiss sectors have reacted with a little anger at this and leave us at a low level, 290 for example as thats what we are filed at. I believe that some levels are "tactically" planned off optimum to avoid slots. That this new restriction is not reflected in our filed levels is a little dissapointing to us too!
