SD Flyer,
Thanks for the advice. I tried entering the segments, however Lowestfare has changed their web-based reservation system so you can't do this anymore. I talked to their customer service people and asked when this functionality would be restored and they said; "maybe soon". They do have a customer service number so I may have to use that. FYI, they charge 5% more to book over the phone.
I'm not quite ready to use Bestfares because I thing there is a travel agent (in Las Vegas I believe) that handles those Ichan tickets.
