Checked with United and the ticket is invalid and needs to be reissued. No such flight from Toronto, it leaves from Calgary instead.

Looking to see what options there may be but I have found in the past that although Air Canada will show availability on Turkish’s star alliance award booking site the handover always fails when you actually go to book it. During Covid I was rebooking a cancelled flight through an agent and he too could see the AC flight but could not book it. On that one he ended up trying to find me a replacement flight as far out in the schedule as he could look for any date and nothing was available. So I had a cancelled flight with points that had expired and no option to rebook. I don’t think I even got my taxes back.

The Turkish site is so wonky, sometimes I see flights available and then they disappear for awhile. I have tried different browsers and sometimes one is better than another. It was actually working better on my iphone but I found if you wanted the 27th date for the flight date you had to select the 26th as your option in the radio button and that was not comforting, made we wonder if this was a translation problem.
