Thanks for the suggestions - I just called in (and spent 0 time on hold which was surprising) and they took care of it. There was a bit of a back and forth because I'd changed it and the reissued tickets were showing T but after a bit of work and insistence that I had the intinerary clearly showing it they eventually found the correct info in the fare rules somewhere.

Just wanted to let folks know. This was an easy one to fix..far less effort than I thought it would be (but about as much as it should be..)

Cheers!
