We have an award ticket issued by United which includes travel on Air New Zealand for the first segment connecting to United for the last three segments. I used to be able to see all of the United segments in Air New Zealand's manage my booking. However, after United changed the final two segments at my request (due to an unacceptable schedule change), those last two segments no longer show on NZ's site (only segments 1 (NZ) and 2 (UA) do, but not segments 3 (UA) and 4 (UA)). Is this an issue I need to have fixed for Air New Zealand to be able to issue boarding passes and check luggage to the final destination? We have a pretty short connection, so if NZ doesn't issue all of the boarding passes, we likely won't make it. I'm just trying to determine if I need to contact United again or if it won't be an issue.

Thanks!
