Thanks for the insight and confirmation.
It's 15 days out, I'm going to leave it as it is for now and if they'd cancel move it to an earlier flight. I still have 24/26/28 as options, and while I'd rather spend the time in Copenhagen, I can deal with needing to move the time a little earlier if it has to be.
I do see the risk though.
I'm booking KL1126 for my November and December flights just to be on the safe(r) side.
