First of all, why does it sound like you're on a plane? But anyways... How long to talk to someone? Well, it sort of depends on the person that you're talking to. Whether it's a guy, a girl, whether you like them or not. If they like you, then they're probably the one. If they don't like you and they've given off so many different red flags, then they're not the one for you, in my opinion.
