I flew from Kenya to Phoenix at 28 weeks, and it was no picnic! My feet got horribly swollen and my lower back was not happy. Also, my son would kick like crazy during take off and landing! So not fun, but after doing the research I felt it was safe. I would be more concerned at 32-33 weeks. Is there an option where you could go from 27-30 weeks or something similar? If not, assuming your doc says it is safe, etc, I would go. I would be sure to identify resources in your destination country- an OB (get your current doc to send records to a doc in destination country and maintain your appointment schedule while you are gone), a hospital, and the best option for a NICU, since the baby would be early if born then. You don't say where you are going, but in Kenya it was very important to get a malaria test while pregnant (malaria is very hazardous to a fetus). I never would have thought of that, so I would definitely recommend going to a local doc AT LEAST once, even if your insurance won't cover it. If you are going to Europe, you will be pleased at the rates you will pay :)
