๐ข Terminal Information
Big Mountain Airport (BMX), originally known as the Big Mountain Air Force Station, is a historic aviation facility located in the remote Lake and Peninsula Borough of Alaska. Established in 1956, the airport was a critical component of the White Alice Communication System (WACS), a Cold War-era defense network designed to provide secure communications and early aircraft warnings across the Alaskan frontier. The station's distinctive tropospheric scatter antennas once dominated the landscape, serving as a silent sentinel in the nationโs northern defense line.
The airport is currently classified as a private-use facility under the ownership of the United States Air Force. Although the primary communications mission was deactivated in 1979 with the advent of satellite technology, the site remains under military jurisdiction. While it is no longer a fully operational base, the airfield is occasionally used for official government business, environmental monitoring, or as an emergency landing site. Civilian pilots seeking to use the facility must navigate a rigorous 30-day prior permission process, as the airport is not open for general public traffic.
Infrastructure at the site is minimalist and reflects its abandoned military status. The airfield features a single gravel-surfaced runway, designated 07/25, which measures approximately 4,200 feet in length. Pilots are warned that the runway is currently unmaintained, and a thorough visual inspection is recommended before any landing attempt due to potential surface deterioration or wildlife presence. The airport sits at an elevation of 1,640 feet, though it is surrounded by much higher peaks that define the challenging approach through the Alaskan mountain ranges.
๐ Connection Tips
Connecting at Big Mountain Airport (BMX) in Alaska is a unique logistical challenge defined by its status as a remote, private-use military airstrip rather than a standard commercial hub. Originally a critical relay for the Cold War-era White Alice Communication System (WACS), the airfield is now owned by the U.S. Air Force and is closed to the general public. If you are 'connecting' hereโtypically for official government business or mission-specific chartersโyou must navigate a rigorous Prior Permission Required (PPR) process at least 30 days in advance. Unauthorized landings are strictly prohibited and can result in significant federal fines.
The facility lacks any form of modern passenger terminal, retail shops, or dining services. Travelers must be entirely self-sufficient, carrying their own food, water, and satellite communication equipment, as local cellular coverage is nonexistent. Navigation is minimalist; 'terminal' functions are handled directly on the 4,200-foot gravel apron or within unstaffed support buildings at the Lower Camp. If you are transiting to a remote research site, your 'connection' will likely involve a direct transfer from a turboprop to a smaller bush plane or 4WD vehicle on the ramp.
Logistically, all operations at BMX are strictly daylight-only under visual flight rules (VFR) and are highly sensitive to the volatile weather of the Aleutian Range. It is essential for pilots to perform a visual inspection of the gravel runway before landing, as the surface is unmonitored and can deteriorate due to frost heaves. Building a 48-hour 'weather buffer' into your itinerary is mandatory, as fog and high winds frequently ground flights for days. Finally, always confirm that your sponsoring agency has pre-arranged all ground logistics and security clearances, as there are no on-site staff to assist with missed connections.

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.
