The world's busiest airport has opened four "lactation pods" for nursing mothers on its concourses, and plans to open a nursing room in the domestic terminal.

Hartsfield-Jackson International opened the Mamava lactation pods in the last couple of weeks, according to spokesman Reese McCranie. The pods are on Concourses T, B, D and F, are free to use and are paid for with advertising.

Each lactation unit has a locked door, bench, changing table and electrical outlet for pumps.

Hartsfield-Jackson is opening the units after an online petition started several years ago asked the airport to put in lactation rooms.

The airport in 2013 sought a company to open a free nursing room along with a children's play area and interactive game lounge, but that contracting process was not completed.
