I'm flying YVR-LAX-ATL Sunday night with only 1.5 hrs in LAX for the connection. When booking I didn't take into consideration that this is an international flight. I am now worried that I haven't left myself enough time to clear immigrations and customs, recheck bags, and switch terminals from Alaska to DL - all in 1.5 hours. I've never transited through LAX so would be grateful for any advice about this. Should I try to reschedule my flights?
