The article is referencing the (delayed) new site. In fact, the photograph printed with the article captures a good bit of the flight search function. Looks similar to AA in that restricted, flexible, full and premium fares are displayed concurrently with each flight option, along with amenity icons like DL.

I am interested to see how the expert mode and search-by-fare-basis functionality translates to the new website. If those two features are lost, then I don't care how slick the new 'flat' site looks, it will be a negative for me.
