"Affectionately known over the years as "the bunker," our 35-level underground facility is more than twice the size of the standard New World Order bunker thanks to DIA's 53-square-mile property. Even after the airport is built out to 12 runways and the capacity for 100 million passengers per year, our bunker still has room to grow! This facility offers secured phone services, sonar-based fingerprint entry technology, on-demand catering and personal services that include water bottle filling stations, free Wi-Fi, information assistance, lost and found, pet services and more. With convenient entrances located in Area 9 (please refer to the map you received at bunker orientation), the bunker is a short walk from the public areas of the Jeppesen Terminal.
