Thankyou Flightwatch. I'd forgotten the Dusseldorf extension to the Amsterdam service. I knew BKS/Northeast had their operational HQ at Newcastle but wasn't aware their Paris service stopped off at LBA. I don't suppose a Trident ever did the honours there on account of the shorter LBA runway back then.
By the way, I believe the present day LBA-LHR service is improving by the day, fog and CAT 1 ILS permitting !
