I am a US citizen. I will be flying from California to New Zealand and back in March 2018. The return leg has a long layover in Honolulu: it arrivesarrive at 6am, and departsdepart at 9pm. All tickets were booked via Air New Zealand, but the Honolulu to California leg is “operated by United”.
I don’t want to spend all that time in the airport when I could see the city instead. But I’m not sure about practicalities. My understanding from this earlier question is that I will need to clear customs and immigration in Honolulu. So my question is, will I need to keep my bags with me all day in Honolulu, or can I drop them off with United at the airport? It would make navigating the city quite tough if I can’t leave my bags at the airport.
