Again, the UA agent told me he couldn't put me on the SFO-YVR flight on UA until AC released the record to them.
So I had no reason to believe I was ever on that flight.
I never received email, I wouldn't know the flight number -- probably told me that day but I didn't retain it because until he told me that I was going to be on that flight, I had no reason to know.
He never told me that I was confirmed for that flight.
1K agent thinks he "held" that flight for me, even if he couldn't put it into the record, under the same confirmation number.
Someone on the AC board said AC and UA have different systems which limit what either side can do to these records. Have no idea about that.
But the same confirmation number which was "cancelled" 24 hours ago now shows the BNE-SFO return flight.
