我找到了一些境外的新闻，写得很清楚：•        the airlines will co-ordinate their schedules where both fly the same route•        the airlines will co-ordinate their schedules in order to match longhaul with connecting shorthaul flights•        the airlines will jointly set pricing on routes between the UK and China•        the airlines will jointly share all revenue on routes between the UK and China, irrespective of which airline carries the passenger•        passengers will be able to mix and match British Airways and China Southern tickets on return trips•        frequent flyer benefits will be fully aligned – this will mean that you will earn an identical number of Avios and tier points if you fly with China Southern or British Airways这样明年飞南航就可以积累到英航得到寰宇一家的会员级别，当然到英航silver还得飞4个英航航班。
