To add to this, I don't believe that the cabin crew can (under normal circumstances) tell if you are an eUpgrade. The one exception may be if they are short on meals and the gate agent actually knows this in time to note this on the manifest, otherwise they shouldn't know. Somebody correct me if I am wrong, but I don't think they would know. Even short meals have to be communicated -- if the GA doesn't do anything, the cabin crew has no way of knowing. AFAIK.
