What's that you say, I'm overthinking it? I would have answered you sooner but I was sorting my spare shoelaces by colour.....
I've only done an international-to-domestic connection at one airport (not LAX, the only time I've been to LAX for a connection I overnighted there.)
Thank you for the followup. I shall endeavour to stop worrying and turn my mind to more important things, like aforesaid shoelaces...
