Dude...a $2 "Safety fee?" Are you nuts? That's like a hotel charging a Clean Sheet Fee. That's something that's expected. Besides, the last thing you want is to highlight "safety"--or ANY, repeat ANY perception of a lack thereof.
Do they only have to pay $1.25/hr if the FO has busted checkride in the previous X months. What about a $1.95/hr if he Captain passed, but had to repeat a maneuver? Will NASA reports be public since passengers are being specifically charged for "safe pilots?" Don't they have the right to know that the company isn't fradulently charging the fee?
Don't open this can of worms...
