Turkish tells me UA cancelled the flight. Surprised they didn’t tell me this directly. Not sure it is even true (would UA cancel a flight and then immediately re-assign the same flight # to a YYC to SFO flight, seems suspicious).

They offered to rebook me (thanks) and gave me one option being a 6 am UA flight, not ideal. And confirmed they could cancel instead but expired miles are expired miles. Didn’t get a clear answer as to whether they would refund taxes but based on prior experience, unlikely.

I am looking at trying to rebook within 30 days. I also lose my star gold status May 31 so extra costs, no lounge access, baggage fees etc.

To add to this they told me they can take up to 48 hours to approve any flight cancellation flight changes and I am running up to that deadline before my flight departure time.

This may not be my first loss of miles and fees due to reasons outside my control. TK Star Gold status was easier to obtain and good while it lasted but miles earned ended up mostly useless.
