Suvarnabhumi's SAT-1 Terminal Opens, Boosting Bangkok Capacity to 60 Million

The Midfield Satellite 1 Terminal (SAT-1) is now fully operational at Suvarnabhumi Airport (BKK) in Bangkok. This major infrastructure project significantly boosts the airport’s capacity. The expansion is a crucial step for Thailand's goal of becoming a premier aviation hub.

Capacity and Operational Boost

The new Midfield Satellite 1 Terminal adds 15 million passengers to the airport's annual capacity. This raises the total annual passenger throughput from 45 million to 60 million. The terminal's soft opening began in September 2023. The official royal inauguration took place in March 2025.

SAT-1 is a key part of the Suvarnabhumi Airport Development Project Phase 2. This project is managed by Airports of Thailand PCL (AOT). The expansion addresses significant overcrowding issues faced before the pandemic.

Key Terminal Features

The four-story SAT-1 terminal covers over 216,000 square meters. It features 28 new aircraft contact gates. Eight of these gates are designed to handle Code F aircraft. This includes large jets like the Airbus A380 and the Boeing 747-8.

• The terminal is connected to the main facility via an Automated People Mover (APM) system.
• This driverless electric train runs along a one-kilometer track.
• The APM allows quick transfers between the main terminal and SAT-1.

Broader Airport Expansion

The SAT-1 opening coincides with other major infrastructure improvements. The airport's third runway also became fully operational in late 2024. This third runway boosts the airport’s flight handling capacity. It increased from 68 to 94 flights per hour. This expansion is vital for managing the rapid growth of international travel into Thailand.

The new terminal is designed to enhance the passenger experience. Its design blends modern architecture with traditional Thai features. The terminal won the prestigious Prix Versailles Prize in 2024. This award recognizes its outstanding exterior architectural design.

Future Outlook for BKK

Airports of Thailand (AOT) is already planning for further growth. The airport's master plan includes a new South Terminal. This future project aims to increase BKK's total capacity to 150 million passengers annually by 2031. The current expansion ensures Suvarnabhumi Airport can meet immediate travel demands. It solidifies its position as one of Southeast Asia's largest aviation hubs.
