Blue islands flew the BRS route in their own right for many years. They then went into a franchise agreement with Flybe till Flybe ceased. The BRS route flight numbers went back to Blue islands flying the route till this covid 19 kicked in in a big way. Blue Islands are due to start the BRS route i think in august but not sure on that one.The BRS route has been flown all year round so i would imagine that will happen again when they restart.
