Unable to do SDC from P fare to P fare
I’m booked in P on UA476 SFO-ORD tonight, and UA278 is showing P1. App shows it would cost me $433 to change. 1K line couldn’t find a price to change it and had to call rate desk. They told her it would cost $433 to book me into Z, even though P is available (she could see it), and that the reason there’s a charge is I was originally in economy and bought up to First two weeks ago.
So the SDC feature is effectively nonexistent.
