Identify the terminal setup. The terminals are split into east and west sides, and each of them has three concourses labeled A, B and C. The Jeppesen Terminal is for those traveling internationally.
Understand where the parking and drop-off areas are at the airport. To drop off passengers, go to departures on level 6. To meet passengers, go to arrivals on level 4. To park long term, go to level 5 or choose a lot on the shuttle route.
Know the basics of how to get around. After you check in, go to the lower level to go through security. Then, go one level down to grab the train. You can get to the concourses typically in less than a few minutes.
Ask for assistance if you need it. Information booths are clearly marked at each concourse and at the Jeppesen Terminal.
Go to DIA's site and review the maps. Print the maps of the different concourses to take with you.
