Delta Air Lines announced this week that effective July 15, flight attendants will only be permitted to wear pins of the US flag on their uniforms after a recent incident involving two flight attendants who wore Palestinian flag pins that mislabeled as “Hamas badges.”

On Tuesday, a user on X/Twitter posted two images of Delta Airlines flight attendants wearing Palestinian pin flags and in the caption described them as “Hamas badges” and also referenced 9/11.

“Since 2001 we take off our shoes in every airport because [of] a terrorist attack in US soil,” the post said. “Now imagine getting into a @Delta flight and seeing workers with Hamas badges in the air. What do you do?” The photos in the tweet showed flight attendants on separate flights on different days — a male flight attendant on a Boston to West Palm Beach flight on July 5 and a female flight attendant on an Atlanta to Fort Lauderdale flight that took place days afterward, according to StopAntisemitism.org.

Delta’s official X account replied to the post, saying, “I hear you as I’d be terrified as well, personally. Our employees reflect our culture and we do not take it lightly when our policy is not being followed.”
