Andy,
What are the demand figures HUY-CDG or ORY? I'm interested to know if the figures that you have really do justify the use of an Embraer 145 - 3 times a day, say - as well as maintaining a 3 or 4 daily KLM service (whether it be F50, F70 or a mix thereof). The demand analysis surely take account of that.
