Not sure how to address this one - I flew Dec 10th on a business flex ticket base value of $1033, which I changed once to a different departure time (same destination) and a second time to a different destination for a refund of $93. Completed the flight. No change fee obviously as it was business flex, however the same locator number. Ticket number (014...) changed each time I changed the ticket. However, now it shows up with a mileage credit in Altitude but does NOT show any AQD (which would theoretically be roughly $1033 minus $93 ?). I suspect they just looked at the last ticket and saw the $93 refund and didn't do the rest of the math.

I do need the credit as I am $288 shy of the $20K needed for SE (have the mileage already).

Do I just write into the missing AQD form with all the history (done) and hope they correct it (that takes some trust in AC...) or do I take a short haul tomorrow to make sure I obtain SE status again.

This sounds pretty straightforward, as though they just haven't gotten around to crediting your flight yet or have made an error. If you've already filled out the form, I wouldn't worry. Generally Audrey and Diana are pretty good with these things.
