Swiss International Airlines - Fares to LX Codeshare Destinations US

I have tried to get Fares to US-Codeshare-Destinations in US (f.e. ABQ,ELP,PHX..) in Summer 2006, which are operated with AA.

There are only displayed fares about 2.800 Euro´s, on swiss-Website and on other reservation-sytems or i get an error-message.

What´s the reason ? It´s because of the ending cooperation LX-AA ?
Why i can´t get fares about 800..1000 Euro´s ?

Does anybody know the reason ? Thank you :-)

Swiss should now be working with United Airlines. If you still can't get anywhere on the Swiss website, I'd go to United's site(ual.com). You'll probably connect through Chicago and then on to your final destination. Your ZRH-ORD flight may be on either Swiss or United.

The problem is, that i would like to have a LX-Metal-Ticket....because of an upgrade on LX for the return flight (that will be from LAX, on LX)

and that´s why i need an LX-Ticket...
