Looks like FlyBE are scrapping the Jersey service, I was looking on their website to book a trip for May next year and tickets are only bookable until December this year, not sure when this month it stops.
No they are not. It is only stopping for about month, from 6 Jan, and starts again on the 9 Feb. For the summer, it's then daily ex Tu/Th.
Also the Isle of Man Route only seems to be operating one rotation a day, I thought this was operated twice daily
.
Has been a single rotation since Nov 08. It was double daily for S08.
