I'm not really surprised, it seems like DEN's new favorite TED boarding procedure is window, middle, isle (WILMA.) In my experience this cuts the boarding time in half. E+ aside, boarding from the back of the plane forward makes sense. From what I've read here, part of the savings UA counts on with TED come from reduced turnaround times. It does stink though since forward bin space is at a premium on the A320's (especially with the crew poaching the fwd overheads!) As long as they let elites board first I'm not complaining
BTW, does anyone know what seating area 4 is? I've had it in the middle of a 757 before.
