๐ข Terminal Information
Sa Pran Nak Airport (KKM), also identified by its ICAO code VTBH, is a significant military aviation facility serving as the primary headquarters for the Royal Thai Army Aviation Center (RTAAC) in Lopburi, Thailand. Situated within the expansive Fort Princess Srinagarindra complex, the airport acts as the central hub for the Army's aerial training and tactical operations. As of early 2026, the base is undergoing a major modernization phase, including the establishment of a dedicated Unmanned Aerial System (UAS) Warfare Center and the integration of a new UAS Battalion to support integrated drone and rotorcraft operations across the kingdom.
The terminal infrastructure at Sa Pran Nak reflects its role as a strategic military installation rather than a commercial passenger hub. While it lacks a traditional civilian passenger terminal, the facility includes specialized processing zones for military personnel, government officials, and VIP delegations. The layout is organized around a large central apron surrounded by multiple battalion-specific hangars and maintenance facilities for a diverse fleet, including UH-60 Black Hawks, Mil Mi-17s, and AgustaWestland AW139s. The complex also houses the Army Aviation School, featuring dedicated training classrooms and high-tech flight simulator centers for the next generation of Thai army pilots.
Amenities within the Sa Pran Nak base are strictly tailored to military logistics and operational readiness. The airfield provides comprehensive support services, including specialized JP-8 and 100LL refueling stations, extensive aircraft maintenance depots, and a category-standard fire and rescue unit equipped with specialized water and foam trucks. The infrastructure features two primary paved asphalt runways: Runway 06/24, approximately 1,186 meters (3,891 ft) in length, and Runway 01/19, approximately 1,006 meters (3,301 ft) in length. These strips are well-maintained to support both light fixed-wing transport aircraft like the CASA C-212 and heavy-lift rotary-wing assets.
Ground transportation at KKM is highly regulated and integrated into the Fort Princess Srinagarindra security perimeter. There are no public taxi ranks or commercial bus systems permitted directly on the airfield apron. Access to and from the site is restricted to authorized military personnel and government contractors, with transportation typically provided by official army vehicle pools. For authorized visitors, the base is located approximately 10 kilometers from central Lopburi, providing a quick 15-to-20 minute transit to regional administrative offices. Travelers and civilian operators are advised that the facility is strictly 'no-access' for unscheduled commercial aviation, and any non-military landing requires prior permission from both the Royal Thai Army and the Civil Aviation Authority of Thailand (CAAT).
๐ Connection Tips
Connecting at Sa Pran Nak Airport (KKM) is a highly specialized process restricted to authorized military and government personnel. Since there are no scheduled commercial airline services, a 'connection' here typically involves a transition from a tactical military flight to local army ground transport within the Fort Princess Srinagarindra complex. Because the facility is an active strategic headquarters, you will not find civilian transit desks or automated baggage systems. Instead, you should coordinate directly with your battalion dispatcher or mission coordinator regarding the manual offloading of equipment and personnel. It is recommended to allow at least 60 minutes for any transition to account for internal security verification.
Ground transportation is the most critical link for any mission transiting through Sa Pran Nak. Since there are no public transport services permitted within the base perimeter, you must coordinate your arrival with the RTAAC motor pool or your respective unit well in advance. If you are being met by an official vehicle, they will typically wait at the designated VIP or battalion pickup zones near the apron edge. Always have your military identification and travel orders ready for inspection, as mobile data signal can be intermittent or restricted within certain secure zones of the base. If your flight is delayed, the battalion waiting areas provide functional shelter, but most authorized personnel prefer to wait in the central administrative buildings.
Practical preparation for a KKM connection includes utilizing the base's internal digital and logistical infrastructure. Secure military Wi-Fi and communications links are available for authorized personnel throughout the headquarters and training school. While there are banking services and canteens within the wider Fort Princess Srinagarindra complex, the airfield terminal area itself does not maintain public ATMs or retail outlets, so having necessary supplies or local currency (Thai Baht) for off-base expenses is a wise precaution. If you have a short wait between missions, the Army Aviation School offers the most comfortable professional environment. Always double-check your departure time with your unit commander, as flight windows at military airfields can occasionally shift due to tactical requirements or air traffic control priorities.
During the peak training cycles and regional military exercises, the terminal area can see exceptionally high activity from heavy rotorcraft and training jets. If your connection is delayed, stay close to your designated briefing area, as flight notifications are primarily managed through unit-specific radio links and may not be audible across the entire airfield campus. Automated self-service kiosks are not available at this location, and all check-in and manifest procedures are handled manually by duty officers. Always have your digital mission authorization and identification ready, as security protocols at Royal Thai Army bases are extremely thorough. For international travelers transiting through major hubs like Bangkok (BKK), ensure you have cleared all national customs and immigration checks before arriving at this restricted regional facility.

๐ข Terminal Information
Chumphon Airport (CJM), also known by its ICAO code VTSE, is a significant regional aviation facility serving the city of Chumphon and the surrounding province in Southern Thailand. Located approximately 35 kilometers north of the city center in the Pathio District, the airport acts as the definitive gateway for travelers heading to the world-famous diving destination of Koh Tao and the neighboring islands of the Gulf of Thailand. The facility is managed by the Department of Airports and has seen steady growth as an efficient alternative to the more congested hubs in Surat Thani or Samui.
The airport features a modern and functional single passenger terminal building that was specifically designed to handle high-volume domestic tourist traffic. The terminal is organized on a single level, ensuring that check-in counters, security screening, and the departure lounge are all within close proximity. The architectural design emphasizes natural ventilation and a bright, airy atmosphere characteristic of Thai regional airfields. The facility has undergone recent modernization to improve passenger flow and accommodate the larger turboprop and narrow-body aircraft that connect the mainland with the national capital.
Amenities at Chumphon Airport are well-appointed for its size, catering primarily to adventure travelers and island-bound tourists. The terminal houses several cafes and snack bars serving both local Thai refreshments and international coffee. For the convenience of travelers, the main hall features dedicated transport desks for 'Lomprayah' and 'Boonsiri' high-speed ferries, where passengers can purchase combined bus and boat tickets directly upon arrival. Other facilities include several retail shops selling beach gear and regional souvenirs, multiple ATMs, and an information booth. Free Wi-Fi is available throughout the terminal, and the airport provides ample car rental options for those looking to explore the scenic Chumphon coastline.
CJM provides robust connectivity to Bangkok, serving as a key operational point for carriers like Nok Air and Thai AirAsia. Frequent daily flights connect Chumphon with Don Mueang International Airport (DMK), providing a rapid link for both international tourists and local residents. Ground transportation is well-coordinated with flight arrivals, with dedicated shuttle buses waiting to take passengers to the various ferry piers, such as Thung Makham Noi, for their onward journey to Koh Tao. Its role as a strategic transport node is fundamental to the tourism economy of the Gulf of Thailand, offering one of the fastest ways to reach the islands from the mainland.
๐ Connection Tips
Chumphon Airport (CJM) is a strategic transit point for travelers heading from Bangkok to the islands of the Gulf of Thailand, particularly Koh Tao. Most visitors use this airport as a link to the Lomprayah or Boonsiri high-speed ferry services. For the most seamless connection, it is highly recommended to book a 'joint ticket' or 'Island Transfer' directly with Nok Air or AirAsia. These packages bundle the flight from Bangkok (DMK), a 60-minute shuttle bus ride to the pier, and the subsequent ferry crossing. Note that only early morning flights (typically departing DMK around 6:00 AM) align with the afternoon ferry departures; later arrivals will likely require an overnight stay in Chumphon town. Upon arrival at CJM, proceed to the ferry operator counters in the arrivals hall to collect your transfer stickers and boarding documents. The shuttle to Thung Makham Noi Pier (used by Lomprayah) takes about an hour. From the pier, high-speed catamarans reach Koh Tao in approximately 90 to 120 minutes. If you have not pre-booked a bundle, you can purchase shuttle-plus-ferry transfers at the airport desks for roughly 800โ1,100 THB. Sea conditions in the Gulf can be choppy during the monsoon season (November to January), so motion sickness medication is advisable. For your return, ensure your ferry departs Koh Tao at least 5 hours before your flight to account for potential sea delays and the land transfer. The airport itself is a small, quiet facility with basic cafes, so it is best to buy essential supplies in Bangkok or upon reaching the islands.
