I have an email from 7 Dec that the company has intended to do this all along and because of the way planning works, this would've been a decision months ago to ensure the aircraft are available. In saying that, it is probably a case of being careful what you announce, as even the best intensions to minimise disruptions might not go to plan depending on the nature of it.
I'd say that 1 flight is not a particular indication of the loads around this time. I've taken a look at some flights for the next week and they are full full full.
