Headscarves/veil for female CC
This has been answered previous, but for those asking again:
Female ground staff may wear a white veil (same as CC scarf) in place fo hat, with approval
Female cabin crew must wear the hat with veil, without exceptions. Once doors are closed the hat is to be removed until after landing. No Muslim female CC wear hijab during the flight, to maintain consistent image.
If you are not comfortable with not being veiled, suggest you apply for job on ground
Hope this helps answer your questions.
