Hi Guys I'm a longhaul flight attendant flying anytime during pregnancy is fine up until 36wks, after 28wks you may need a Drs letter depending on airline. I had to be grounded as soon as the company found out I was pregnant and now work on the ground.I found out at 4 1/2 weeks but did 2 more flights before I let them know. Many girls work up to the 12wks then let the company know and all have been fine. The risk of radiation is so small, higher the closer to the equator you go, and if you fly on a regular basis as cabin crew and business pax do. I flew to barcelona at 5wks returned at 6wks and going again to germany tomo 1owks returning at 11wks. i am not too concerned.If it was that bad the wouldnt allow you to fly at all! honestly the risks are so small, you would have to fly daily for it to be risky. At the end of the day the choice is yours, but the reason cabin crew are grounded is because of health and safety, very small rediation factor, the amount they fly, the tiring effect of time zones and physical aspects of the job ie moving heavy carts around, having to open shut heavy doors, emergancy evacuations and carrying suitcases about not practical if you are pregnant. hope this helps. I am possibly planning a sun holiday to Dubai or caribbean around 5-6 mths too if all is well. Dusty x
