I probably said this before in the flight crew 'Medical and Health' bit, but from what I have read so far, the effects of flying on pregnant mother and the embryo/fetus seem to me to be a little worrying. I would personally not like to fly if I become pregnant, as the risks of miscarriage and other things going wrong seem to be exacerbated by flying. I am aware that JAA regulations allow pregnant flight crew with normal pregnancy (after obstetric evaluation) to fly up to 26 weeks, so I presume the same applies to cabin crew.
However, it is nice to be given a choice of flying or not flying as long as the pregnancy is normal, so that a woman can make her own decision ...
Most of the airlines I have come across (bear in mind I do not work in the industry) or heard about seem to ground the pregnant aircrew on discovering the pregnancy and offer a ground position or unpaid leave.
