Storm in a tea pot , Tehran policy for trousers ( no skirt) and head scarf for CC is as old as the Iranian revolution and was followed without problems until 7 years ago when AF stopped flying to Tehran. Now they will restart OPS there and AF management just reminded both cabin and Flight crew of old regulations. A CC union picked it up and wanting to make the Buzz raised an issue..
Media picked it up, politicians in presidential campaign took it on board , etc..
This morning AF announced that Crewing to THR will be on voluntary basis only but following the local rules, that CC Union seem to be happy. End of story.
An for those who have been in THR in the last 5 years you can see that covering your hair is in fact today only covering 1/2 of it on the back , every year the women gain 1 cm as the local joke goes.
