There is a specific thread that covers Contract IDs, and the OP already started the discussion there yesterday:

I am not sure its appropriate to have a separate thread just about one specific Contract ID, but that is something the mods can decide.

As per my response in the other thread, I am still able to use the KLM code for an overseas reservation, but no luck for 2 stations I tried in the US.
