Had MX issue a couple of weeks ago, got switched from a DTW routing to an ATL routing, sent in ORC request via twitter (which has worked in the past), agent says no prob, I've sent it to skymiles team.

Two weeks go by with no response, skymiles still shows the flown credit instead of the ORC.

I send another twitter DM, next agent tells me "I see your ticket and it was credited" and I'm like "yeah I see it's credited but it's credited as flown, not as originally ticketed." Then they say "you can only receive credit for the flights​ you have traveled. Our system doesn't allow us to issue credit on the original routing."

two minutes on the phone and the issue is fixed.
