I got the Air Canada status match, posted on DDMS. It said if we fly a round trip on Air Canada before Jan 15, 2022, the status will extend until end of 2022. I was looking at a flight on Air Canada, and the same flight cost $50 cheaper if I book it through United. (will probably also count as a United booking if I do it through Amex biz plat points, so I could get back 35%).
Would such a flight count to extend my status (if I book on United, is it considered a United flight, or AC)?
