Before the recent bout of problems it was still a route with condsiderable problems. One issue alone was the security and the Uk government requirments for extra security checks and continuous audits. On top of this crew accomodation, passenger visa checks and the arrival searches of the a/c by the religious police that often left the a/c in a compete shambles and used up valuable time. All services are provided by the state owned handlers and costs the earth and there is not much attention to safety. Good luck !
