Yesterday (14th) I made some conflicting bookings for tomorrow (16th). I booked a YYC-YKA round trip, YYC-YVR, a YVR-YEG round trip, a YYC-YYJ round trip, and YVR-YYC.

All stayed intact for over 24 hours. I got alerts to check in for all 8 segments. I just went to check in for the flights I decided to take (the YKA and YYJ turns), and I see that the YYJ turn has disappeared, once again without any advance notice or ex post notification. It disappeared somewhere after check-in for the return opened, which was just under 8 hours ago, or somewhere between 21 and 14 hours before departure of the first segment.

What's bizarre is that the system still hasn't cancelled all the conflicting bookings. It's impossible to fly the YKA turn while also doing the YVR and YEG trips, but those are all intact. So it's not even good at the job that it's supposed to do

Bloody ridiculous system, this, and really starting to annoy me.
