Yet another MCT worry. I am flying in to MIA on AA and then flying out to LIM on LATAM, which I understand is at the opposite side of the airport. 1:15 connection time. I can certainly run if needed, but what worries me is security at J gates. LATAM does not do PreCheck, but AA will be printing my boarding pass in DEN. Any chance they'll be able to get PreCheck onto my LIM BP even though the flight is marketed and operated by LATAM?
