My partner (Australian) and I (American) are visiting Canada and the US in October. Our last flight back home involves either a 4.5-hour layover in LAX or a 1.5-hour layover in SFO. Both options are single ticket through either Delta (LAX) or United (SFO), United being the flight with a 1.5 hr layover.
I am more than sure that the 4.5-hour layover will be overkill, as I will go through immigration quickly and he should be a bit quicker, as he will be able to use those kiosks for non-residents who have visited the US in the last 5 years (we will have just spent 2 weeks there prior). Still, 1.5 hours ins't a lot of time. My questions are:
- Are we required to go through immigration/customs for an international to international flight?
- Is 1.5 hours enough time?
