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
Connecting through Chicago O'Hare International Airport (ORD) requires careful planning, particularly when transferring between the main domestic terminals (Terminals 1, 2, and 3) and the primarily international Terminal 5. After re-checking your bags, take the ATS to your domestic departure terminal and clear TSA security there.
A highly efficient alternative for passengers on a single ticket who do not need to collect their luggage is the Terminal Transfer Bus (TTB). If the TTB is not running, or if you are on separate tickets, you must use the landside ATS and re-clear security at your next terminal. O'Hare is a place where terminal choice and connection timing matter, because the airport is large enough that the wrong assumption can cost real minutes. A minimum connection time of at least three hours is strongly recommended for international-to-domestic transfers to account for potential CBP delays and terminal changes.
Unlike the domestic terminals, Terminal 5 is physically separate and is connected to the rest of the airport via the 24/7 automated Airport Transit System (ATS). This airside shuttle operates daily between approximately 11:30 AM and 9:30 PM, allowing you to move between terminals without exiting the secure area or re-clearing security. Utilizing the Mobile Passport Control (MPC) app can help expedite the immigration process.
For most international arrivals, you must clear immigration and customs at Terminal 5, collect all checked baggage, and then re-check your bags at the dedicated airline counters located just past the customs exit. The TTB can be accessed from Gate M13 in Terminal 5, Gate C18B in Terminal 1, and Gates G17 or K20 in Terminal 3. Travelers should also note that some domestic carriers, such as Delta and JetBlue, now operate out of Terminal 5, so it is essential to verify your departure gate on the information screens before heading to the main terminal core.

๐ข Terminal Information
Ambler Airport (ABL) is a remote, state-owned public-use airport located in the Native Alaskan village of Ambler, within the Northwest Arctic Borough. It serves as an indispensable lifeline for this isolated community, as there are no connecting roads. The airport's infrastructure is extremely basic, reflecting its role as a bush airport. There is no traditional terminal building; instead, operations are conducted from a small, heated shelter or a designated waiting area adjacent to the gravel runway. This single facility serves as the waiting lounge, check-in area, and baggage claim point.
The airport is equipped with two gravel runways, the longest measuring 3,000 feet, operating at an elevation of 334 feet above mean sea level. This design accommodates the small aircraft, typically Twin Otters or Cessnas, that are vital for connecting Ambler to larger regional hubs. Passengers should anticipate a highly informal process, with direct interactions with pilots and airline representatives from operators like Bering Air.
Amenities at Ambler Airport are exceptionally sparse. There are no cafes, restaurants, vending machines, or shops on-site. Travelers are strongly advised to bring all necessary provisions, including food, water, and personal supplies. Security procedures are minimal, consistent with bush flying operations in remote Alaska, focusing on adherence to general aviation safety guidelines.
๐ Connection Tips
Connections at Ambler Airport are exclusively through domestic bush flights, with Bering Air being the primary scheduled carrier. These flights are crucial for linking Ambler with the regional hub of Kotzebue (OTZ) and nearby villages like Shungnak (SHG) and Kobuk (OBU). Kotzebue's Ralph Wien Memorial Airport serves as the main gateway from which most flights to Ambler originate, providing essential connections to Anchorage via Alaska Airlines. Because there are no roads connecting this isolated part of the Northwest Arctic Borough to the rest of the state, these regional air links are the only way to transport supplies, personnel, and medical essentials to the community. Travelers should expect a highly personalized but informal experience, as flights often operate as multi-stop 'milk runs' across the Kobuk River valley.
Travel to and from Ambler is highly dependent on unpredictable Arctic weather conditions and available daylight hours. Flights are frequently subject to significant delays or total cancellations due to adverse weather patterns, including dense fog, heavy snow, or high winds, which are common throughout the year. It is crucial for all travelers to maintain flexible itineraries and to confirm their flight status directly with Bering Air or their charter operator before heading to the airstrip. Unlike major commercial airports, there are no inter-airline baggage transfer services here; all luggage is handled manually by the pilot and ground agents upon arrival and departure. Always prepare for the unexpected and carry essential items in your carry-on, as the challenging environment can lead to extended stays in regional hubs like Kotzebue.
Ground transportation in the village of Ambler is extremely limited and primarily relies on local community members or pre-arranged pickups from your lodging provider. There are no traditional taxi services, Uber, or rental cars readily available at the airport, which is located about 1.5 miles north of the village center. Most residents and visitors use ATVs (four-wheelers) during the summer and snow machines in the winter to navigate the gravel road between the airstrip and the community. Bering Air typically has a local agent who coordinates arrivals and can assist with logistics, but it is vital to have a clear plan for your ground transport well in advance of your touchdown to ensure you are not left stranded at the remote airfield.
Self-sufficiency is paramount when traveling to such an isolated destination, and coordination with local providers like the Kobuk River Lodge is highly recommended. This lodge is the primary provider for both accommodation and meals in Ambler and can often assist with arranging the necessary transport from the airport. During the summer months, travel between Ambler, Shungnak, and Kobuk can also be conducted via small boats on the Kobuk River, though this is a local arrangement and not part of any formal transit system. Having a thorough understanding of your ground logistics, including pre-booked lodging and a confirmed local contact for pickup, is as critical as your flight plan when navigating the unique challenges of the Alaskan bush.
