On April 6, Istanbul Ataturk Airport — which was considered one of the busiest airports in the world with 70 million annual passengers — officially ceased operations. All commercial flights were transferred to Turkey's new flagship international airport, which means Istanbul New Airport is open for business.

The first flight at Istanbul New Airport took place October 2018, and now the airport's first phase of construction, which includes three runways and 15 million square feet of terminal space, is finished. There are four phases to be completed by 2025, with a total cost of about $12 billion.
