There are two Premium lines just like before. If you are coming from United area then it's against the wall. This is probably a bad design if things are busy because you would have fight your way through.

The other area is just above the "other" escalators on the western end. The Premium line is on the right -- if you are coming from the west (parking garage 2) make a sharp right as you pass the British Airways counters.

Basically the whole thing has been reversed. In the past "other" airline passengers would queue along the wall and the UA had the "corral".
