NW is touting that they won a comparison done by ZD on airline website usability. The complete story is here:

I'm not sure who the heck did these studies, but I've used NW's, CO's, UA's, AA's, and DL's site to book tickets, and if you ask me the ratings are bogus. I think DL's site is much easier to use than any of the others, yet they're ranked below all of them (except CO which isn't ranked) ...

Am I the only one who finds the DL site the most user friendly? What do you guys/gals think ...
