Purchased a ticket on the 19th for a flight departing on the 21st, returning on the 24th, connecting in ATL on the return. On the 22nd, I called in and rebooked the return for the 23rd through DTW (this was after the 24 hour cancellation period, but I was given the change for free (both itineraries were in Q, no fare difference) (I mentioned to the agent that I tried calling in over the weekend when there were tons of IROPS and hold times were insane, which may have helped avoid a change fee)).

I boarded the flight to DTW, then deplaned after a DTW ground stop made it obvious that I would miss my connection. I rebooked in the club through ATL. Flights posted as flown, I requested ORC via twitter and nothing happened.

The ticket was reissued when I did the voluntary rebooking on the 22nd, and I got an email with the new return routing and a new ticket number. The return flight posted with a 3rd ticket number (I'm assuming it was reissued again when it was rebooked in IROPs but I didn't get a receipt for that).

Today I called in and was told that since no fare difference was collected, any ORC request would use the original ATL routing (so no credit for the DTW booking is possible). This... seems incorrect but I'm not really sure. I have definitely done SDC to a longer routing then had IROPs to a shorter routing and gotten ORC for the longer routing in the past, but this wasn't a SDC (even though it was confirmed).

I'm not going to spend a lot of time fighting this since it's only 112 MQM difference but would like to know what my expectation should be here.
