The Expert Flyer 'Availability' for Flight 34 YVR to YYZ on Sep 19 shows 13 business class seats available, however when I spoke to the call centre agent they indicated there were only 5 seats. Would EF be incorrect? This seems like a big discrepancy. I am not looking at the seat map, but the actual availability for J, C, and D fare class. If there were only those few seats I would look for a different flight for Eupgrade availability, but the other flight I would take also (shows high availability for those fare classes and I am not sure now of the accuracy.
