Sorry if this is an old topic, but

Can anyone explain how BA charges a fuel surcharge when booking AA transpacific flights? especially when the AA web site states:

“Fuel surcharges are assessed on each fare component.
Surcharges do not apply to the following passengers: passengers who are traveling on free tickets, including free AAdvantage tickets; domestic passengers whose ticket does not reflect a broken fare from the surcharge city.”


BA want around $300 round trip. Is it only me who thinks this is unethical?
