This is a new one for me, but then again I can't recall the last time I cancelled a ticketed PNR. Anyway, my flight to PSP was cancelled multiple times with the recent storm, so I ended up cancelling the ticket for a refund with no viable options left. The reservation is no longer anywhere to be seen, and I got an email confirmation of the refund a few hours after I cancelled. However, today about 3pm CDT would have been the check-in time for my return flight, had I taken it, and the APP sent two push notifications that it was time to check-in for my PSP-PSP (NOT PSP-xxx) trip. (For valid notifications, I also get an email, which did not occur.) Just wondering if anyone else has seen this odd behavior?
