IAD - Z gates to D gates?
Is getting into IAD at the Z gates on US and then connecting to an international UA flight in the D gates fairly straightforward?
From what I can gather on the terminal map for Dulles, I can walk to A and get a people mover to D or I can take a train from Z to C and walk to D. Which would be more predictable in terms of time? The itin I have on hold right now has a 2-hr layover. Not sure if carry-ons will need to be gate (valet) checked but if so will have to wait for that too.
