Hi There,
no didn't flew it yet. Will be End of January. I am in serious trouble anyway with tons of schedule changes, sending back and forth between Saudia, my travel agency and the airline which issued the ticket (which is different than SV). Plus in Frankfurt SV staff all say me I will never able to travel with a two stop connection in KSA anyway...
Alone with this experience I would not recommend you to a) book a two stop connection in SV and b) even less on two tickets, especially with all the schedule changes I received which will cause you serious headache if you receive similar things.
