This is a note especially for those sisters who are nervous about traveling through airports with the new scanners.
I had to travel from JFK to Zurich to Qatar this November, and the minute the security saw me (hijaabed), the female ones took me aside to a private room, where they did a regular scan/manual check. Relatively quick, professional and respectful. It was no worse than before the scanners, which I'm glad I didn't have to go through it at all. It was almost like they *knew* I would refuse it.
That may just be my experience, but it was at more than one airport.
