Regarding the other site you listed, as far as I know, it's FAA law that all flights are refundable within 24 hours of purchase (unless the flight itself is departing within 24 hours).

Edited to add: You do say "Fare Basis" and not fare class, as I see now and removed my instructions for forcing specific fare classes.

Reason: Clarifying fare basis versus fare class.
