Do Emirates, Etihad and Qatar fly Israeli citizens?6
In the case of Kuwait Airlines, they refuse to fly anyone with an Israeli passport, does not matter whether Jewish, Druz, Christian or Muslim, they claim this has nothing to do with antisemitism, it is an issue with the state of Israel. This guy is a Muslim Palestinian from a village that was part of Israel from 1948, and they consider him an Israeli.
