๐ข Terminal Information
John Glenn Columbus International Airport (CMH/KCMH), named in honor of the legendary astronaut and U.S. Senator, is the primary commercial airport serving Columbus, Ohio. As one of the largest and busiest airports in the state, it acts as a significant hub for nationwide domestic travel and offers seasonal international connections to Canada and the Caribbean. The airport is a critical piece of infrastructure for the central Ohio region, supporting the diverse needs of both leisure travelers and business professionals visiting the area's many corporate headquarters and the Ohio State University.
The terminal at CMH is a unified structure featuring a central ticketing and arrivals hall that branches out into three distinct concourses: A, B, and C. Concourse A primarily handles Southwest Airlines, while Concourse B is home to American Airlines and United. Concourse C serves Delta Air Lines and additional regional carriers. Throughout the terminal, passengers have access to a wide array of modern amenities, including diverse dining options ranging from quick-service snack bars to full-service restaurants, a variety of retail shops, and high-quality Wi-Fi. The airport is also known for its extensive public art collection, which is prominently displayed throughout the terminal to enhance the passenger experience.
Operational capacity at John Glenn International is supported by two significant paved runways, with the longest (10L/28R) measuring approximately 3,125 meters in length, capable of handling large wide-body aircraft. Navigating through the terminal is relatively straightforward, as all concourses are connected via a centralized passenger corridor. For ground transportation, the airport is conveniently located just 10 kilometers from downtown Columbus, with a variety of options including official taxi services, frequent shuttle buses, and multiple car rental agencies located in the dedicated car rental center. Travelers are encouraged to use the designated rideshare pick-up zones, which are clearly signed and located just outside the terminal entrance.
๐ Connection Tips
John Glenn Columbus International Airport (CMH) is an easy airport to understand once you know one key detail: the terminal is divided into Concourses A, B, and C, and Fly Columbus publishes separate TSA checkpoint hours for each concourse rather than a single central checkpoint. For a connecting passenger, that matters because your planning should start with the departing concourse, not just the airport name. If you reach the wrong checkpoint area or leave security for food, pickups, or bag issues, you may add unnecessary time to the connection.
CMH is still far simpler than a mega-hub. Distances are short, the terminal is compact, and official guidance recommends arriving at least 90 minutes before domestic departure and two hours before international departure. That is a useful baseline for self-transfers as well. The airport handles most domestic connections smoothly when both flights are on one ticket and use the same general side of the terminal, but separate-ticket itineraries deserve a bigger cushion, especially if checked bags, weather disruption, or late inbound arrivals are involved.
A practical rule at Columbus is to verify your departing concourse before you clear security and again after any gate change. If you are switching airlines, traveling with children, or moving during a morning or holiday rush, give yourself more time than the airport's compact size suggests. CMH rewards passengers who know their checkpoint, monitor gate changes, and avoid treating a three-concourse airport like a single undifferentiated post-security hall.

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.
