Hair today, gone tomorrow. As the airline restarts service to Tehran, it’s stirred controversy with an internal memo asking female flight attendants to wear head scarves and loose-fitting clothing in Iran as a nod to cultural norms. In France, full-face veils worn publicly for religious purposes are illegal. While flight attendants already don abayas on Saudi Arabian stopovers, crew members protested the latest request, leading to a union fight. Air France finally conceded that staff can opt out of the Paris-to-Tehran route when it launches April 17.
