Wiggy,
I have been told that all women, locals and foreigners, are expected to cover their hair when out and about in Iran. This is the same as Saudi Arabia, which AF has served for many years.
AF has said they will permit their cockpit and cabin crews to opt out of Iran flights if they choose.
“In Iran, the law stipulates that all women present in the country have to wear a headscarf covering their hair in public places," Monday’s news release stated. “This obligation does not apply during the flight and is respected by all international airlines serving the Republic of Iran.”
