With only one terminal building at DRT, finding your way around here is a breeze. Have a look at the airport's official website to discover what services and amenities are available in the departures lounge. To play it safe, arrive 1.5-2 hours ahead of your departure time for domestic flights. If you're traveling internationally, get to the airport 2-3 hours in advance. This will leave you enough time to pass through security and customs and then make your way to your gate. Add extra time if you're flying during peak periods, such as Christmas.
