Also AC will NOT interline with Oneworld, period. Even on a single PNR!!!!! They will interline with Star on the same PNR, but not on separate PNRs -- far worse policy than QF or AA have, as a point of comparison. I guess they feel it gives Star a competitive advantage; it has kept me from flying AC when they had the most convenient schedule (and they now have some very nice new planes, so it isn't always grim to fly AC).
