I was one of the last people to fly on this: Mid May 2023. Even though LA had notified me months before that the ticket was cancelled, I went to the airport anyway since my booking never disappeared from the check my flight section on the web site. I had not done anything actively as I really didn't care if I could fly or not. It was just a short trip of a few days for me, no hotels/car booked in advance, not visiting friends or anything, so I figured I'll just take my chances and see how it'll turn out.
Well, I could do OLCI without any issues, and flew this fare in Business as if everything was perfectly normal.
So I guess it was kind of random, and I was just lucky.
