Is it fine if a woman with 2-mo pregnancy air-travels half the hemisphere for about 12 hours long?

You should be fine. If you have any questions you should really talk to your doctor about it. He can give you a better answer.

There is nothing wrong with it. The real risk comes much later in your pregnancy.

Be prepared for some major swelling of your feet and ankles, and if you've been having morning sickness, you're in for a bumpy ride. If you can handle that, you should be fine. Congrats!

yep you can untill you are around 7 months or so

First off, you need to get a check-up from your doctor to make sure you are in fit enough health to fly. Most airlines will not require you to have a medical certificate from your doctor this early on, but you should verify this with your airline.

I will be traveling internationally (24 hour total travel time!) this summer while pregnant as well. I will leave Friday, when I am 13 weeks, and return when I am around 30 weeks. I have also traveled internationally with my first two pregnancies (my children are now 7&5).

Airline regulations state :

Obstetrical patients are free to fly, but pose a significant risk in later stages of precipitating delivery during flight. Pregnancy past 32 weeks should be carefully considered for restriction from flight and must be accompanied with an authorization note from a doctor. Those past 36 weeks should be prohibited from flying unless personally accompanied by their doctor.

Please note that while airline regulations do not prohibit flying while pregnant, and even if you bring a doctors note, the final decision is entirely up to the Captain (who will be informed by the gate crew of your status).

While traveling I advise you to keep your medical records, and the name and number of your doctor. You should also get the name and number of a doctor where you will be staying/visiting in case an emergency comes up.

To keep yourself safe and comfortable on the trip, follow these simple things:

*drink plenty of water
*avoid caffeine
*don't eat food that causes gas for at least one day before you travel (pressure builds up as you ascend through the altitudes and could cause pain)
*walk around as much as you can (up and down the aisles)
*stretch while sitting
*wear loose fitting clothing
*wear slip on shoes (your feet may swell)
*wear maternity support pantyhose or socks
*try to get an aisle seat or a front row seat for more leg room
*eat light foods
*eat small meals or snacks at frequent intervals rather than big heavy meals
*do not eat salt
*ask for a seat belt extender and wear it just under your abdomen
*try to relax

I hope you have a safe (and uneventful) trip. If I can be of any more help or assistance, please feel free to contact me
