We are travelling from Zurich (Switzerland) to Kona (Hawai'i) and have the following flights to choose from:
ZRH-SFO-KOA with 1.5h connection time in SFO, all flights operated by United or ZRH-SFO-KOA with 2h connection time in SFO, first flight operated by Swiss, 2nd by United.
We are wondering if those connection times are enought? We are both swiss citizens and we will have a checked in luggage.
Do we have to go through customs? and do we have to get our luggage in SFO anyway?
Has anyone experience with those flights or would you recomend an other option?
