Nwa.com won't give you a lot of the choices, too. I noticed that you're also a West Coaster, and for us West Coasters, arguably some of the most convenient routes to Europe won't show up at nwa.com (e.g., in your case LAX-CDG-FRA, LAX-IAH-FRA). The website is pretty good at showing NW stuff, KL stuff, and some DL stuff (sorta). It really doesn't like to show CO without some prodding, and AF, you really gotta force it.

The sad thing is nwa.com is one of the better airline sites out there in terms of reward redemption. UA, for example, can't handle a single partner; CO can handle some, but not a multi-city/open jaw.
