Is it safe for pregnant woman to travel by air?

It is safe until after 32 weeks.

I have never done it myself, but from what I have heard, a woman can travel until she is in her third trimester, or around 7 months.

Yes, up until 36 weeks.

i cant remember the exact specifications, but i dont think your suppose to fly after your first trimester, but call and confirm that with your doc.

In your first and second trimester, Yes, although if you have pregnancy complications such as spotting, diabetes, high blood pressure or a previous premature delivery check with your doctor before travelling. As long as your pregnancy is normal, it's safe to go ahead and make travel plans as usual. Most expectant mums find that the second trimester -- weeks 14 to 27 -- is a perfect time to travel. With morning sickness behind you, your energy levels high and the chances of miscarriage low, you can enjoy the luxury of relaxing, sleeping in and dining late with your partner. You can also take advantage of travelling light -- with no car seat, buggy, nappies or toys in tow.

In your third trimester, As long as you don't have medical complications, aren't carrying twins or more, and haven't had any prior premature deliveries, you can fly on most airlines until 36 weeks of pregnancy. Travel agents and airlines won't ask if you're pregnant when you book your seat, but you may be challenged at the check-in desk. For this reason, from about 28 weeks of pregnancy you will need a letter from your doctor confirming your due date and stating that you are unlikely to go into labour on the flight! Check your airline's policy on flying in pregnancy before you leave and don't forget that it applies to your return trip, too.

oh and dont worry, cos There is no evidence that recreational flying is harmful to your growing baby. Cabin pressure won't affect your baby; in fact, you're more likely to have problems flying in a small plane that doesn't have cabin pressure. Oxygen gets significantly thinner at high altitudes, which means your body has to work hard to supply you -- and your baby -- with sufficient amounts.
Heavy exposure to atmospheric radiation during flying has been linked with an increased risk of miscarriage and, for this reason, many airlines take the precautionary step of grounding female flight attendants during the first trimester of pregnancy. However, flight attendants make hundreds of flights each year and doctors agree that the risk to women who only fly occasionally is miniscule.

I think you are not allowed in the first 3 months nor the last 3 months, but it is ok for the 3 months in the middle???

Yes. of course

How pregnant? And is she having a normal pregnancy?

Normally, the rule of thumb is that you can fly into your 35th week. But if you're carrying more than one baby, if you're experiencing complications, etc. those rules can change. And remember, she'll have to able to fly BACK before her 35th week is up - so watch not only the departure date, but the return as well.

It's also true that the distance travelled makes a difference - flying can be uncomfortable later in pregnancy when our bodies tend to swell up more easily. So longer flights are tough, and being wedged into those little seats? Not fun. Plus, when you're headed to the doctor every other week - or every week, late in pregnancy - it's practically challenging to travel.

If there's any doubt about safety or possible problems, make two phone calls: first, to the airline you intend to fly and second, to your doctor.

Personally, I like to stick fairly close to home in the third trimester. I did fly (and it was fine) around 30 weeks with baby #1, but this time I'm lucky to be able to stay on terra firma for the last few weeks.

yes until third trimester
