Well, the renovations are far from complete, but when I flew out of D this morning, gates 27 A&B and gates 29 A&B were being used for 328jet flights.
The lower level is open, including a new stairwell in the middle of the stem of concourse D.
There are new bathrooms open on the lower level and a handful of some great looking chairs! Thick cushions, and each with a moveable writing table. There are about 25 of these on the lower level with their backs to the moving walk way, and then on the ends there are 3 or 4 couch style seats, long enough for a person to stretch across (Each one had someone taking a nap this morning!)
The new restaurant near gate D32 had it's menu posted this morning: breakfast items in the morning and soups, salads, sandwiches and appetizers for lunch/dinner.
There is still a lot of touch up/finishing work to be done on D, but so far the improvements look nice.
