I can't be bothered to test the timetable to see when they drop LTN~IOM and I doubt that it yet states if it comes back in the Spring ...
It finishes at the end of October and the closure is permanent. It will not be reintroduced in the spring. The rotation is being transferred to LGW which will then have a 4 x daily service. This has been on the cards for months and was expected, especially since Aer Arran began operating the route.
For the winter, Aer Arran will operate a daily, afternoon departure on the IOM-LTN route.
