I can understand the disquiet at being economical with the truth over charges. KLM charge an almost flat 99euros on EU destinations. This includes some nebullous details as 'Administration costs'. What are they when the whole thing is done by computer. Then there are reservation costs. How the h@#l do you making a booking in advance without a reservation; again wholly by computer. Then there are the credit card charges. It is the only way to book over the internet. The airport taxes are bundled in with the admin costs, so the whole matter is very opaque! They hasve you by the short & curlies because there is no alternative if you want to travel. Do it all in an agent's shop and it more expensive. Thus, the total price for most EU destinations comes to double the cheapest ticket cost. The whole matter is a con, but I suspect the eurocrats will find out that the bag of worms they are playing with is far too big and difficult to sort out, and let it slide under the stones.
