Using United award miles, can both a stopover and an open jaw be permitted from LAX/SFO to Australia/New Zealand? For example, fly to Melborne on Air New Zealand via Christchurch, do a stop over in Christchurch, then fly on to Melbourne. But, for the return, fly from Sydney to LAX/SFO on either United, or Air New Zealand, via Auckland? Or, vice versa on the itinerary. Therefore, doing this type of routing, it appers to be a combination of an open jaw and a stop over. Is this permitted using United award mileage? Thanks.
