If you’re having a healthy pregnancy, absolutely! And you should — because once baby comes, it’ll be difficult just to make it to the grocery store, at least for a while. Just make sure to get up and walk around during your flight to avoid deep vein thrombosis (DVT) which is the formation of a blood clot deep in the vein. Pregnancy increases the risk of DVT due to your body's natural tendency to prevent excessive bleeding during childbirth. You should also drink plenty of water to combat dehydration. Check with your doctor, but if you’re having a normal pregnancy, most OBs say you can travel until 32-36 weeks. After this point, you run the risk of going into labor while in the air.
