Can someone please help me check my math?
If I have a flight at 1300 MST on 04 Jan, assuming NF>0, my upgrade should clear by 0900 MST on 31 Dec, correct?
My math equates 100 hours (1K UDU window) to 4 days (96 hours) and 4 hours.
4 days from 04 Jan should be 31 Dec. And four hours from 1300 should be 0900.
Upgrade changed from "pending" to "waitlisted" on website. However, NF>0 so it should have cleared at 0900. I just got off the phone with two UA agents who said that I'm a "few hours too early."
