Question to CPYVR.

For E and SEs, the route controller can release economy revenue seats for awards, this can be done for business class seats only for SEs?

Does the route controller release the seats, or can the Aeroplan agent do it himself/herself? Or put it another way, if the Aeroplan agent sees in the screen that there are no award seats, is it possible that the Aeroplan agent may say nothing is available, without going to the route controller?

Finally, is there a route controller for Aeroplan awards on Star Alliance partner airlines?
