Out of interest, is the whole Oneworld interline concept supposed to be that the service on each airline within the alliance is similar? If so, my recent experiences on AY, IB and QF show great disparities. IB was dire, but what did I expect...but AY and QF were excellent, and the product onboard very different to the BA equivalent. Just wondering as the experiences mean I would not now choose BA to HEL in Y or BA to BKK in J or Y.
