Yes it is on the same ticket. I mentioned about the insurance because if something goes wrong, I won't need to sleep at the airport.

Looks like 75 minutes is pushing it. Based on past 2 weeks, CA112 has a 33% chance of being 30 minutes late, and there is 20% chance that AC32 would depart within 30 minutes of CA112. I guess I will either pick a 3 hour connection, or maybe a 7 hour one so I can wander out for a few hours.

Shortest layover I have done is 35 minutes in Guam, and the first flight was late by over 30 minutes. Essentially rushed to the other gate but at least there was no passport check and Guam airport is small.
