Jakarta. Soekarno-Hatta International Airport, Indonesia's largest and busiest hub near Jakarta, by June will move all international flights to Terminal 3.

The terminal was opened in August, after three years of construction works to expand it, which cost Rp 7 trillion ($516 million). It is now significantly bigger than the other two terminals.

It can serve up to 25 million flights a year, spans 420,000 square meters and is 2.4 kilometers long.

"We're are going to have all international flights moved to Terminal 3 by June," Yado Yarismano, vice president of the airport's operator Angkasa Pura II (AP II), said on Wednesday (14/02).

He added that now, when all expansion works are complete, the terminal needs to be assessed by the Transportation Ministry's directorate general of civil aviation to serve all international flights.

Revamp of Terminal 1 and Terminal 2

The airport's Terminal 1 and Terminal 2 will also be expanded to accommodate together 36 million passengers a year — twice more than before.

Contractors will soon be invited to bid to partake in the Rp 3.2 trillion project.

"The bidding for Terminal 1 starts in March, while for Terminal 2 in May, so construction works at the first one will start sooner," AP II president director Muhammad Awaluddin said.

He added that both terminals will be finished by August 2019.

"The revamp won't disrupt our operations, as it will be done in sections, so the terminals will still serve passengers. We also won't change their architecture, we will just add more room," Awaluddin added.

AP II is now also preparing to build Terminal 4 of the size and capacity of Terminal 3.
