Hi Everyone,

My father has a flight out of Concourse E (Qatar Airways) from MIA and 2 hours later I have a flight out of Concourse D (American). I would like to accompany my father to his departure gate and then proceed towards my departure gate after he boards. QR 778 usually leaves from E11. Are concourse D and E connected post security? If they are not, can I still clear security at Concourse D with him, then exit and re clear the security at Concourse E?
