Soekarno-Hatta International Airport is still the main gate for flights from and to Indonesia. The airport is the world's third busiest airport in 2018, according to OAG Aviation Worldwide Limited. Is it the reason behind the airport’s decision to build Terminal 4? The number of flights in Soekarno-Hatta Airport can answer the question. Angkasa Pura II recorded that the airport received 63 million airline passengers throughout 2017, an 8% increase from the previous year. In the same report, Angkasa Pura II also recorded that international routes experienced growth in passenger numbers by 12%, from 13.1 million in 2016 to 14.7 million in 2017. Meanwhile, the passenger numbers on domestic routes in 2017 rose 7% from 45 million in 2016. The increase was in part due to the opening of Terminal 3 of Soekarno-Hatta Airport in August 2016, adding a capacity for 22 million passengers per year. Currently, the airport is able to accommodate up to 60 million passengers per year. However, the growing capacity is still unable to keep up with the rising passenger numbers in 2017. Therefore, a construction of Terminal 4 is deemed necessary. Angkasa Pura will use the land near the airport to build Terminal 4. The current plan is to use Soewarna Business Park warehouse area. Terminal 4 will have an area of 300.000 m2, or 100.000 m2 less than Terminal 3. Nonetheless, Terminal 4 is expected to have an optimal capacity. "I want Terminal 4’s capacity to be at least the same as Terminal 3’s. If possible, Terminal 4 will have a capacity for 40 million passengers, twice as many as the capacity of Terminal 3," Angkasa Pura II Operation and Engineering Director Djoko Murjatmodjo, as quoted from bandara soekarnohatta.com on Sunday (July 23, 2017). Angkasa Pura seems to have prepared a blueprint of future Soekarno-Hatta International Airport. It is hoped that Indonesia's most renowned airport will be able to accommodate more passengers. In addition to passenger capacity, airport transportation service is another important thing to be considered amid the growing number of passengers. Passengers need the best transportation service from and to the airport to avoid the long wait and queue. TRAC as a subsidiary of PT Serasi Autoraya (SERA) offers airport transfer service at numerous airports in Indonesia. As part of Astra, TRAC provides a transportation solution with professional drivers and various high-quality vehicles. These benefits naturally bring a sense of security and comfort to airline passengers who need a ride from the airport to their destinations.
