Thank you for that response. I wasn't able to find the answer I was looking for on Delta.com and since I got a low miles award ticket in J, I wanted to try to SDC onto another flight with less connections and possibly onto the AirBus 330!
Do you know where I can find the info that says that I can be SDC'd directly into first in case I talk to someone who doesn't know? That way I can refer them to that info. Or do I just hang up and keep calling back until I get someone that will do it for me?
