Not a dedicated nursing room and not particularly suitable for nursing, but best option available in Terminal C (next proper nursing room apparently available only in Terminal D). Delta information desk staff (or staff at gate C28/security staff nearby) lets nursing moms use the unaccompanied minors room to the left of gate C28 (unmarked white door). The room is less than ideal because it has a lot of large windows. Also, the security staff insisted on leaving the door ajar - she would stand right outside in front of the door and make sure nobody would come in. However, the room is large and it is possible to find a somewhat secluded spot. There are at least two electricity outlets (one next to the fridge), a fridge stocked with bottled water, a lot of chairs, unfortunately no washing facilities.
