Red Wing 6,
Those are the only 3 I could find mentioned that offer points for Sprint PCS. There are several other airlines that offer points for Sprint residential long distance as can be seen here.

As for when does the Norhtwest relationship end, I believe it is 3-31-03. I received a notice about this via snail mail approximately a year ago. I don't have any web links that specify this end date, however you can look at my post on this old thread.

I was able to get my bsigned up right before they stopped taking new enrollments. You should have received some notification about the 3-31-03 term date awhile back.
I am waiting til my points for March post to Worldperks and then probably I'll try and get points on United for Sprint PCS. I don't plan to change my cell service so I might as well get points for it w/ some FF program.
