The E-Trade ad in the current issue of Hemispheres (the UA in-flight magazine) says you need to respond by May 31, 1999 so my guess is that is the real (latest) end date.
And yes, I finally got my ClickReward points from the Holiday bonus promo with E-Trade (although it did take two additional e-mails to ClickRewards to straighten everything out)!
