Usually it's the last 5-6 or so shows released that will show on board. Now, who knows how the Fox movies are going to play into this. So here's the release schedule from Maleficent up through early Feb:
Maleficent 2 Oct 18
Fod v. Ferrari (Fox) Nov 15
Frozen 2 Nov 22
The Last Jedi Dec 20
Spies in Disguise (Fox) Dec 25
Underwater (Fox) Jan 10
The King's Man (Fox) Feb 14
Now, if we toss out all the Fox movies, I would say definitely it would be on board. But I think (not 100% sure) that they are showing the Fox movies onboard (anyone?) so that could muddle things up a bit. I still think your chances are pretty good, even with the Fox movies in there. Other than Spies in Disguise, I can't see them showing those other Fox films non stop.
