Can an airline really do this?
Yes, the airlines which now no person of good will should ever fly, has admitted that Israelis cannot fly on their planes. How dare they!
This from Wikipedia
"Kuwait Airlines was accused of discriminating against holders of Israeli passports, for refusing in 2013 and 2014 to sell tickets from New York to London to people holding such passports.
In response, Senator Richard Blumenthal, along with five other USA senators, wrote a letter to Transportation Secretary Anthony Foxx in May 2015 urging him to investigate the allegations. In October 2015, at the conclusion of an investigation, the US Department of Transportation issued Kuwait Airways an order to “cease and desist from refusing to transport Israeli citizens between the U.S. and any third country where they are allowed to disembark”
Additionally, New York City Council member Rory Lancman asked the Port Authority of New York, which operates JFK Airport, to "terminate the airline’s lease if it doesn’t immediately change its policy". For its part, the airline said that it is in compliance with Kuwaiti Law which prohibits the company from entering "into an agreement, personally or indirectly, with entities or persons residing in Israel, or with Israeli citizenship.”
I'm disgusted. And shocked. And grateful to my friend Debra in the US who sent me the link. I echo the words of the Jewish prophet Amos: “Let justice roll down like waters and righteousness like an ever-flowing stream." (Amos 5.24)
