I've always known flights originating from Brazil are free of fuel surcharges.
However when I priced out a J award ticket GRU-IST-LIS to my surprise I saw:

Taxes and fees BRL 1,385.76
- Embarkation fee BR 62.86
- Service charge DU 0.00
- Fuel Surcharge YR 1291.06
- Airport Service Charge 31.84

Question to the Brazil M&S members or anyone who knows is this common to see this?
Mistake or legitimate charge?

I understand there is a difference between YR/YQ but anyone know if Brazil also restricts YR charges as well? or just YQ?

YR Insurance and security surcharge
Many airlines have been levying a charge per passenger to cover increased costs of insurance and security. It is usually represented by the tax code YR.

YQ Fuel surcharge
Many airlines have imposed a separate fuel surcharge. It is usually represented by the tax code YQ. The amount of the fuel surcharge varies by airline, route and sometimes cabin of travel.
