As far as I'm aware the routes to the far east take the aircraft north over Turkey, then over the CIS and east towards India (with which Israel has relations). Now I'm sure BKK flights take that route, but HKG flights may take the same route as flights to Beijing, ie across China (always a good way to get to Beijing!!) and down towards Guangzhou and HKG. For a 767 that might be best, as it would be considerably shorter. The delivery of the A330-200 will make life considerably easier for EL AL on this and other Asian routes, as it will have a longer range and better t/o and payload lift performance than the 767.
