When leaving US you are only paying
US September 11th Security Fee (AY) $5.60
On the way back you are paying
US September 11th Security Fee (AY) $5.60 (or more if you have a long layover in USA)
Chile Airport Facility Charge International (ZQ) $30.00
US Customs Fee (YC) $5.50
US Immigration Fee (XY) $7.00
USDA APHIS Fee (XA) $3.96
+ Argentinian taxes (already mentioned) + US International arrival tax (?)
Actually, $91 in taxes is not too bad.
