If you are viewing Dollars/Points results and want to see Award availability, or vice versa, in a single step, append a fareType parameter to the URL line as follows:
- &fareType=DOLLARS
- &fareType=POINTS
- &fareType=TRANSITION_CERTIFICATE
Sorry it took so long to come up with this one: it's been a long time since I've had much reason to use the web site, especially for comparing Award availability and fares.
UPDATE: Be sure to do this on a "fresh" search results page. If, for example, you have used the calendar tabs to adjust the date for which information is displayed, the base URL may have changed, there may be no parameters, and fareType switching attempts may only produce an error.
