one related question on fuel surcharge / taxes...what's the situation for codeshare flights ? e.g. for a flight I'm taking BKK-SYD...it's operated by BA but codeshare by QF as well...can I avoid the high BA surcharge by taking the QF codeshare ? (or is QF equally high as well?) Similarly for SYD-SFO, does the fuel surcharge diff between the QF flight # and the AA codeshare # ?
thanks a lot.
