In all fairness to the airlines, I think there are valid concerns with flying into Tel Aviv, particularly since Hamas has boasted that one of its goals is to take down a passenger liner entering or leaving that airport. I believe El Al flights have anti-missile technology, whereas ours do not, generally.
I notice that a congressman has just introduced a bill to get US airlines to add some kind of anti-missile systems. I don’t know if that means your jolly Delta pilot is going to have to get into shooting them down...but a lot of them are exmilitary, so they could probably handle that!
When Southwest first started up, they were very heavy into military pilots. They probably still are.
