Both, but I wasn't clear - this is two separate UA flights, not a UA and NZ flight... I'm wondering if at check-in time the bags can be checked through at the first UA check-in?

 

 

 

 

UA could easily do this, but I've never needed to do it so can't offer any advice. UA did clamp down on interlining with non *A carriers a few years ago and are under no real obligation to offer it.

 

Like interlining with NZ if you are *G and ask politely at the Premier Access counter then I guess you'll find out.
