I have been calling daily trying to get YYZ-SFO AC business class award seats for over 2 weeks now and none was available. When I do a search on tix availability, the following comes up:

YYZ SFO 1520/1800 AC 755 J9 C9 Y9 M9 B9 H9 V9 Q9 L9 N4 T1 (320)
YYZ SFO 1945/2224 AC 759 J9 C9 Y9 M9 B9 H9 V9 Q9 L9 N9 T1 (320)

Does that mean they have plenty of seats in business but only for revenue pax?
Any idea how often these people release seats for award redemption? Thanks.
