The only 3 European Oneworld airlines that I see is Finnair, Iberia, and Malev, and all have a
symbol, so how do I know that they don't have a fuel surcharge, when you yourself didn't know. And even if they all don't have a surcharge, am I correct that the cheapest economy ticket with BA miles, is AA-Finnair, AA-Iberia, or AA-Malev, and if so what's the preferred way?
