Actually very buggy. I was looking at flight 9, YYZ-YYC-NRT. For YYC-NRT, it shows as operating until April 25 and on days 4. For YYZ-NRT, it shows as operating until April 27 on days 5 and 6, and until May 29 (except April 28-30) on days 237. So day 4 for the first presumably meant x4. Also the 237 flights after April 27 are missing from the YYC departure. YYZ-YYC is consistent with YYZ-NRT.OTOH, one can still book flight 9 for later dates.
