The third runway at Jakarta's Soekarno-Hatta International airport entered commercial service on 15 August.
The new runway is initially operating to a length of only 2,500m, however that is planned to open up to its full length of 3,000m around November.
With a three-runway system in place, Soekarno-Hatta's movement capacity grows to 114 flights per hour, up significantly from the 80 it has been limited to with its two runways.
Soekarno-Hatta is Indonesia's primary hub airport, but growth has been constrained for several years due to a lack of infrastructure and overcapacity.
In addition to the third runway, operator Angkasa Pura II is building a fourth terminal at the airport and refurbishing Terminals 1 and 2 to raise the capacity of each building to 22 million passengers per annum.
