Appears to be correct - from a quick look only the afternoon service is bookable in November.
By coincidence I was on yesterday mornings NCL-DUB flight (we usually fly to BFS, but EZY have dropped the early morning flight for the summer - seems to be back for the winter). Flight was about two thirds full - no idea about the number of transfer pax (though the two lasses in front of me we definitely going to New York...)
The evening RYR flight back was rammed - that might be the story.
