I am flying from DFW to IND with a layover in IAD. I am scheduled for my interview at IAD for 4:00 p.m. and my flight to IND is at 5:02 pm. Will that be enough time for me to get to my interview and back to my flight. This will be the first time will be at IAD.

(The next appointment available at DFW isn't until Sept. 15)

Sorry if this has been asked before, search doesn't really work that well. :P
