I guess, it depends on your definition of 'scamcharges'.
If you are meaning 'YQ' - scamcharge
sensu stricto and seemingly arbitrary per other posts.
But if you are meaning more like the all up extra cash charge for reward tickets, then that can and usually does include some unpleasant, but quite real and set costs such as airport-imposed passenger fees (securtity, landing, airport improvement ...).
Here are some I saw posted in another thread:
$54.20 Swiss Passenger Security and Noise Charge
$39.50 France Domestic & International Airport Tax
$21.30 Spain Departure Charge
$5.80 Spanish Security Tax
$48.40 France International Passenger Service Charge
$23.40 Thailand Domestic Passenger Service
$477.80 Fuel Surcharge
... and Canada has its own verion of many of these of course
