Should be ok if incoming flight is on time. It’s about a 15 min walk from the H to D gates. The D concourse is huge, so use the free train on the upper level once you get to the D concourse, if necessary depending on your departure gate. (There is no train between H and D, walking is the best way). And, you will have to clear security once you get to D.Edited: May 13, 2021, 11:58 pm
Thank you so much! Just wanted to be sure we weren’t going to be sprinting from one to the other.
