Any idea what the cost of an EI J award would be DUB-SFO one way? 25K Avios + ??

Per ITA

USDA APHIS Fee (XA) $5.00
US Immigration Fee (XY) $7.00
US Customs Fee (YC) $5.50
Irish Passenger Charge (UP) $21.10
EI YQ surcharge (YQ) $19.90
Irish Inspection/Pre-Clearance Charge (UQ) $9.30
US International Arrival Tax (US) $17.50

So about $83.93

Trying to see if its wprth flying LHR-DUB (4.5K Avios + $27.50 RFS) + SFO-DUB

vs
LHR-LAX-SFO AA 20K Aadvantage (off peak) +$203.60 USD
