AKIPRESS.COM - On April 6, Istanbul Atakturk 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, CNBC reports.

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.

The new airport covers 76 million square meters (more than 818 million square feet or 18,780 acres) and can currently handle 90 million passengers a year in phase one. When the entire airport is completed, it will be able to handle 200 million passengers a year. That will make it the world's biggest airport by passenger traffic. In comparison, Hartsfield-Jackson International Airport in Atlanta, currently the world's busiest airport, handles 107 million passengers a year.

The airport also has a Yotel, a 451-room boutique hotel that has both "land-side" and "air-side" access. Those booking air-side (located near Duty Free) don't have to leave the airport after they deplane. Land-side bookings are for passengers who have not yet gone through customs and passport control.

The air traffic control tower at Istanbul New Airport, which is 22 miles from Istanbul, is shaped like a tulip, a popular and symbolic flower in Turkish culture.
