What airlines do Jews currently use to fly to Jeddah?
I think that’s the point. It is a violation of what passes for “law” in Saudi Arabia that Jews, or any Israeli, excepting Israeli Muslims or Palestinians with an Israeli passport, try to enter Saudi Arabia at all.
So if an airline wishes to fly to Saudi Arabia, they must exclude such people at their destination point.
No particular reason to get excited about this, as Delta can fly Jews and Israelis anywhere else.
I might add that the US no-fly list excludes a lot of Muslims from coming to the US, even though they have only vague association with anything terrorist.
What Jews fly, walk, or otherwise travel to Jeddah?
