With all respect to you and the initial poster, I disagree. You feel like this, only because you are new to this web site. I feel the same way when I visit Delta web site after got familiarised with NW over the last 4 years !
NW reservations do have the option to see all your reservations in one page, you can change seats after reservations etc etc. Spend a little more time, you'll get used to it.
