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) features a highly efficient but unique layout that passengers must understand when planning a connection. The airport consists of a single main terminal building connected to three distinct concourses: A, B, and C. The most critical operational detail for travelers is that these concourses are not connected airside. If your connection involves switching between different airlines that operate out of different concoursesโfor example, arriving on Delta in Concourse C and departing on Southwest in Concourse Aโyou must exit the secure area, walk through the main terminal, and re-clear security at your new concourse. Because of this requirement, it is recommended to allow at least 60 to 90 minutes for any connection that involves a change of concourse. Fortunately, the walking distance between concourse entrances in the main terminal is very short, typically taking only 3 to 5 minutes. Each concourse has its own dedicated security checkpoint, and while TSA PreCheck is available at all three, the CLEAR expedited screening service is currently only located at the Concourse B checkpoint. If you are connecting within the same concourse, such as between two American Airlines flights in Concourse B, your transfer will be seamless and won't require re-clearance of security. CMH offers several amenities for those with longer layovers. The Escape Lounge, located in Concourse B, is accessible to most passengers for a fee or through various premium credit card programs. Dining options are plentiful within each concourse, though many close by late evening. For ground connections, the COTA AirConnect bus provides a direct link to downtown Columbus, and the rental car center is a short walk from the baggage claim area. Always check your departure gate and concourse upon arrival to determine if a security re-clearance will be necessary for your onward journey.

๐ข Terminal Information
Lehigh Valley International Airport (ABE), located in Allentown, Pennsylvania, serves as a vital regional gateway to the Lehigh Valley and Eastern Pennsylvania. It offers a less congested and more convenient travel experience compared to larger metropolitan hubs. The airport features a single, modern terminal building spread across two levels, designed for efficient passenger processing and easy navigation. The lower level is dedicated to arrivals, housing baggage claim, car rental counters, and exits to ground transportation. The upper level manages departures, with ticket counters, airline check-in desks, and the Transportation Security Administration (TSA) screening checkpoint.
The airport continually invests in enhancing its passenger facilities. A recent TSA Checkpoint Terminal Connector Project has significantly upgraded the security area, incorporating up to four screening lanes, modern escalators and elevators, and an enhanced air purification system. The terminal is structured with two main concourses: Concourse A on the ground level serves airlines like Allegiant Air, American Airlines, and Delta Air Lines, while Concourse B on the upper level is utilized by United Airlines and Frontier Airlines.
Amenities at ABE are well-appointed for a regional facility, including several cafes and snack bars, shops for essentials and souvenirs, and free Wi-Fi throughout. ABE also offers family-friendly amenities such as a children's play area, a sensory room, and a therapy dog program, along with occasional live music performances, creating a welcoming atmosphere for all travelers.
๐ Connection Tips
Lehigh Valley International Airport (ABE) is primarily a domestic airport, with most connections occurring within the United States. Its compact single-terminal design significantly simplifies the connection process, as there's no need for shuttle buses or trains between terminals, and walking times between gates are typically short. However, all connecting passengers, including those on domestic flights, must pass through a TSA security checkpoint. Travelers should be prepared to place all electronics and liquids (up to 2 liters) in separate trays for X-ray screening, as per TSA regulations.\n\nFor any onward domestic flights, it's recommended to allow at least 1.5 to 2 hours between flights, especially during peak travel times or early morning departures, to ensure ample time for security and gate transfers. While ABE does not handle international immigration or customs directly, passengers connecting from an international flight at a larger gateway (like Philadelphia or Newark) to ABE should account for the time required to clear those formalities at their initial point of entry into the U.S.\n\nABE offers convenient options for expedited security screening, including dedicated lanes for TSA PreCheck and the CLEAR program, which can significantly reduce wait times. Ground transportation to and from the airport is readily available, with taxis, ride-sharing services, and car rental companies all operating on-site. Local LANTA bus services also connect the airport to various points in the Lehigh Valley.
