๐ข Terminal Information
Denver International Airport features a distinctive architectural design with its iconic tent-like roof structure inspired by the snow-capped Rocky Mountains, creating one of the most recognizable airport profiles in the world. The airport operates through a single main terminal building connected to three concourses (A, B, and C) via an efficient underground automated train system that provides reliable service throughout the day.
The main terminal houses all check-in facilities, baggage claim areas, and ground transportation access points on multiple levels, with the train station located on Level 5. Concourse A primarily serves United Airlines and its Star Alliance partners as United's major western hub, Concourse B accommodates various domestic and international carriers including American, Delta, and international airlines, while Concourse C handles additional United operations and other carriers. The underground train system operates with frequent service, typically every 2-3 minutes during peak hours and every 4-6 minutes during off-peak periods, making connections between concourses quick and convenient.
Security checkpoints are positioned on Level 6 of the main terminal, with separate north and south checkpoints serving different concourses, plus dedicated international and United Club security areas. TSA PreCheck and CLEAR lanes are available at all checkpoints, with wait times ranging from 15-25 minutes during standard periods to 45-90 minutes during peak travel times, holiday periods, and weather delays that are common during Colorado's winter months.
International operations are distributed across all concourses with customs and immigration facilities located in the main terminal's Level 5. International arrivals proceed through comprehensive CBP facilities including Global Entry kiosks, while connecting passengers follow marked paths to the train system. Weather-related delays are frequent during winter months due to snow and ice conditions requiring extensive de-icing operations.
The airport offers extensive amenities throughout all areas, including restaurants featuring Colorado cuisine and local breweries, retail shops highlighting Colorado products and outdoor gear, and multiple airline lounges including United Clubs in all concourses, an American Admirals Club, and several independent lounges. The airport is renowned for its art installations throughout the terminal and concourses, free Wi-Fi, abundant charging stations, and family-friendly amenities including nursing rooms, children's play areas, and pet relief facilities.
๐ Connection Tips
DEN is United Airlines' hub. The underground train connects all concourses. Allow extra time during winter weather.

๐ข Terminal Information
Ambler Airport (ABL) in Alaska, USA, functions as a very small, remote regional airport, serving the Native Alaskan village of Ambler and its surrounding isolated communities. It is primarily a lifeline airport for essential services, cargo, and occasional passenger flights, connecting to larger hubs like Kotzebue, with services often provided by Easy Fly Express. Its terminal facilities are extremely rudimentary, often consisting of a single, basic building or a simple shelter that acts as a modest waiting area and a point for cargo handling. The layout is minimalist, with direct access from a small gravel landing strip to the boarding area, often a designated spot on the tarmac. There are no complex multi-terminal configurations or extensive ground facilities; all operations are conducted within this singular, basic setup. Walking times are negligible, typically mere seconds from arrival to aircraft, emphasizing its functional role in providing essential access to remote regions.\n\nSecurity procedures at ABL are minimal, consistent with its classification as a small, remote regional airfield. Formal TSA security checkpoints are typically not present for the limited passenger traffic. Instead, security protocols focus on general aviation safety guidelines and direct coordination with local air carriers or charter operators like Easy Fly Express. There are no significant wait times for any checks. As a domestic airfield, there are no immigration or customs facilities on site; these functions would be handled at larger international airports for any international travel. Passengers should expect a highly informal and direct process, reflecting the very low volume of air traffic and the challenging operational environment of rural Alaska.\n\nAmenities at Ambler Airport are exceptionally sparse. Passengers should not expect any airline lounges, dedicated dining facilities, or retail shops. Any available provisions would be extremely limited, possibly from a very basic local store in the village, and travelers are strongly advised to bring all necessary supplies, including food, water, and personal items. Seating in the waiting area is basic and often outdoors, and very limited. Accessibility features are rudimentary, primarily consisting of ground-level access. Travelers requiring assistance must coordinate thoroughly in advance with their air operator or local contacts. Family facilities, such as play areas or nursing rooms, are entirely absent. The airport's primary purpose is essential logistical support and access for remote communities, not passenger comfort or convenience.
๐ Connection Tips
Connections via OTZ; operations can be weather and daylight dependent.
