Its the same as overflying anywhere........ but more sand!!! If you have a clearance, which is not hard to get, you will be fine. For the first 10 minutes over Saudi, you will controlled by Bahrain, they will hand you over to Riyadh who will do 2 things
!) Ask you for your "OTILA" estimate (border Saudi & Jordan)
2) Tell you to contact Jeddah abeam "RAF" i think
Assuming you dont forget to contact Jeddah....... some 30 minutes later, Jeddah will tell you to call amman on 128.5 at Otila
So you will transit Saudi without really saying much to anyone.
If you are tech stopping, fuel is cheaper in beirut than Larnaca!
Good Luck
