The direction of this doesn't look good...If premium fares "special offers" are gone, this will take away most of the excitement for being on this fora. Plus, whenever a good discounted fare becomes available (like a $1500-1700 TATL biz fare), we won't know if it will be honored.
Anyway, the DOT temporary ruling should have been "things will stand as they are, until we figure the new guideline out" and not "you don't have to honor fares, until we can figure this out".
