prior to that. when they were jersey european. pre 2000
from airchive.com
flybe IOM-BHD, IOM-BLK, IOM-LCY spring to mind
edit: correction - got a route wrong. its was IOM-BHD, IOM-BLK, IOM-BRS were previously operated by jersey european. which as you say became british european and more latterly flybe. as you can see it was 1998.
so i would say they have dropped routes.
