Checking awards w/o login?
 

Does anyone know which airline sites let you check award availability without requiring a login? Swiss, AA and Continental are some; are there others?
I'm trying to add support to Mileage Monkey (http://jph.bytestacker.com/award.htm) to actually check award availability. I know you can see some availability via ExpertFlyer, but this requires a login.

You can check for award availability on nwa.com without logging in, but elite members give up the potential that their status may increase their access to standard awards compared to base members.
