Flight departure delay to US at AKL meant missing the last flight connection at Houston so was moved to the next days flight. A few issues with checking in etc but eventually united sorted.

Issue now is there is no return leg when logging in online at all, and in the app its removed all seat, terminal and manage my booking options. Vaguely remember this happening on a flight years ago and it rectified. Any ideas what's going on? Will call AirNZ later today. United printed a return itinerary which seems in order, mainly concerned about my months in advanced confirmed RU of course!
