I too have had DM agents mention that I have used SDC "a lot". And, almost every time it is a battle to get it done. Being told that my fare class is not available. I fly all first class fares, so moot point. Me having to tell them to check their KM or ask a supervisor for help.

But hearing a lot of others are having these issues (I thought I'd just had a lot of uninformed agents) makes me wonder if DL will be limiting the number of times we can SDC. Or just get rid of it completely.
