I think that this is penny pinching to be honnest. How much does it cost to fly the aircraft to and from Edinburgh?
Eurocharges add about 25% to the DOC.
On the question of going airways if you are paying EC, yes in principal, but I then have to fly further, am subject to slot delays and have less flexibility in weather avoidance.
Quick straw poll. Does anyone here pay EC (themselves) and advocate paying them?
