Awesome, happy to help. I'm only recently getting up to speed on all this stuff. Glad it worked out and you got upgraded!
FT does indicate that if you get the right agent, there is seemingly quite a bit of rule bending for the SDC.
Also need to point out that when asking for any change, it's best to come with a plan to be implemented and not ask them to come up with a plan. I do this all the time and it's a totally different ballgame, especially during IRROPS. While other complain, I walk up knowing which flights I want to get on. All they have to do is put the plan into action. Take that together with a smile and you're golden, unless the agent is having a bad day.
