Yes, I want a full F fare. Looks like I will have to call them because each time I select a flight, the web page throws an error. Will try to clear my browser's cache and try one more time...

EDIT: Aaargh. In spite of clearing browser cache and even trying another browser altogether, Delta's web-site continues to throw the same error upon selecting a flight: "Oh no! We're sorry, there was a problem processing your request....If you continue to experience problems, please contact....". The site appears able and fine to do searches (and quickly), but choosing any flight results in the same error. Called Delta and received the expected "delayed waiting times" message owing to the recent storm.
