I am quite sure that people are being charged a departure fee that they should not be charged. I have been charged additional fees, varying from departure to departure, on leaving Belize.
Here is a quote from an email I just received from Taca. I will be very interested to see what happens when I leave next time.
"Thank you for contacting us Mr. Warren,
We would like to inform you that all taxes are included on your ticket already, so don't worry cause you won't have to pay anything at the moment of your departure from Belize.
Best Regards,
Atte,

I would suggest more of us research this.
