๐ข Terminal Information
OโHare International Airport has four terminals: Terminals 1, 2, and 3 form a horseshoe connected by airside walkways, while Terminal 5 handles most international flights and sits across the airfield. The Airport Transit System (ATS) train links all terminals, parking, and the rental car center on a frequent loop.
Walking between concourses inside the domestic complex is straightforwardโConcourses B and C in Terminal 1 are joined by the underground neon tunnel (5โ7 minutes end to end), Terminal 1 to Terminal 2 takes about 8โ10 minutes, and Terminal 3โs farthest gates are 12โ15 minutes from Terminal 1 via secure corridors. Travel to Terminal 5 requires exiting or riding the ATS from the domestic terminals; the train ride is about 8 minutes with another few minutes of platform access.
Each terminal hosts multiple TSA checkpoints with PreCheck and CLEAR lanes; the main checkpoints in Terminals 1 and 3 open earliest for banked morning departures. Typical waits run 15โ25 minutes, but peaks before 7 a.m. or during holiday afternoons can exceed 35 minutes, so the TSA โMyTSAโ feed is useful for live estimates. Re-entry from Terminal 5 to domestic gates requires clearing security again.
Immigration and customs for most international arrivals are handled in Terminal 5โs expansive arrivals hall with Global Entry, Mobile Passport, and baggage re-check desks for onward connections. Certain precleared arrivals from Canada and select international flights on United or American may use facilities in Terminals 1 or 3, but transfer passengers should follow airline-specific signs before boarding the ATS.
Amenities are extensive: United Polaris and United Club lounges populate Terminal 1, Delta Sky Club sits in Terminal 2, and Americanโs Admirals Clubs and Flagship Lounge anchor Terminal 3. Terminal 5 offers lounges for Delta, Air France/KLM, British Airways, and others, plus a large dining court. Nursing rooms are available in every terminal, โKids on the Flyโ play areas sit near Gates F1 and in Terminal 2โs rotunda, and all concourses provide elevators, moving walkways, and adult-changing stations for accessibility.
๐ Connection Tips
ORD is a major hub with extensive domestic and international connections. Terminal 5 transfers require re-security screening. ATS runs every 5 minutes.

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.
