Pregnancy and Flying
Pregnant women need not be restricted from flying. Most airlines permit pregnant women to fly until the end of the 35th week of pregnancy, whereupon expectant mothers are strictly advised not to fly. Exact stipulations from airline to airline vary, and it is well worth contacting airlines in advance of flying to confirm their regulations. Some airlines may request a medical certificate specifying the expectant date of delivery. Follwing are for your reference only.
Singapore Airlines
Expectant mothers in good health can be accepted for travel under the following conditions:
Normal Pregnancy: Mothers can be accepted up until the 35th week of pregnancy. If pregnancy is up to limiting dates, passenger should hold a certificate of fitness for travel.
Multiple Pregnancies: (twins, triplets etc) Mothers can be accepted up until the 32nd week of pregnancy.
If more than one month elapses between date of booking and date of departure a new doctors certificate is required and must be issued no more than three days outside departure date.
Virgin Blue
Women can fly with Virgin Blue until 35 weeks in their pregnancy without producing any documents. After 36 weeks expectant mothers must have a medical certificate issued for medical clearance before they are able to fly.
Qantas
Medical clearance is only required if you are having complications of pregnancy. International travel is not permitted after the 36th week for routine pregnancies or the 32nd week for routine multiple pregnancies. Some countries place limitations on the entry of non-national pregnant women. It is best to check with the local consulate if in any doubt.
For domestic travel there is no restriction for a normal uncomplicated pregnancy but medical clearance is required if you wish to travel past the 36th week for uncomplicated multiple pregnancy.
Tips for Flying When Pregnant
The risk of DVT is greatly accentuated and DVT preventative in-flight socks should be worn. Flight stockings can be purchased at many pharmacies for around $50. Their manufacturers claim that they can be worn up to 30 times, and are available in several sizes.
Background cosmic radiation levels are also higher at altitude, which can be harmful to the foetus. Expectant mothers are, therefore, recommended to avoid flying during the first three months of pregnancy if possible.
Pregnancy, represents one of the most valid times to splash out on a business or first class ticket, especially if you are making a long haul flight. Leg rests encourage better circulation, and greater leg room will provide greater comfort, then the more cramped economy class.
Seat belts should be worn low around the pelvis.
Avoiding immobility for the duration of the flight is paramount for expectant mothers, as the viscosity of their blood tends to increase. Try walking around the plane at regular intervals.
Consume plenty of water throughout the flight and avoid the consumption of heavy foods which, through prolonged immobility, can lead to stomach cramps and pain.
Do not take sleeping tablets to circumvent jet lag, instead try to realign your sleeping patterns.

孕妇不必禁忌坐飞机，大多数航空公司都允许怀孕35周或以下的孕妇飞行，之后就建议最好不要坐飞机了。不过每个航空公司的规定都不一样，所以最好联系你将要乘坐的航空公司以了解他们的规章制度。一些航空公司可能需要医生开的预产期的证明。以下是一些航空公司的规定，以供参考：
新加坡航空公司：
在以下条件下，身体健康的孕妇可以乘坐飞机:
正常怀孕：怀孕35周或以下的孕妇可以飞行。如果怀孕接近35周，需要医生证明孕妇适合飞行。
多胞胎怀孕（如双胞胎，三胞胎,等等）：怀孕32周或以下的孕妇可以飞行
如果订票和起飞日期超过一个月，孕妇需要一份新的医生证明，并且证明必须在起飞日期3天之内的。
Virgin Blue
怀孕35周或以下的孕妇都可以乘坐virgin blue 的飞机，而且不需要医生证明。36周以后，必须有医生的证明才能飞行。
Qantas
只有怀孕过程复杂的孕妇需要提供医生证明。正常怀孕36周以后，和多胞胎怀孕32周以后将不能乘坐国际航班。不过有些国家对非本国公民孕妇入境有限制，如有疑问的话，最好和入境处查询。对于国内航班，对正常的孕妇没有任何限制，但是36周以上的多胞胎怀孕则需要医生的证明。
孕妇乘坐飞机的小贴士：
孕妇应该知道相对其他人，飞行对胎儿和孕妇的风险要大的多。
深静脉血栓的风险大大的增加。孕妇应该穿上预防深静脉血栓的袜子。这种袜子可以在各大药房里买的到，价钱50元左右。制造商声明这种袜子可以重复使用30次，而且有不用的号码。
飞行高空的辐射比较高，这可能会对胎儿造成伤害。所以孕妇最好在怀孕的前3个月避免飞行。
孕妇最好乘坐商务舱或头等舱，尤其是长途飞行。较大的空间可以让腿得到充分的舒展，也更加舒服。
安全带最好绑在盆腔以下
最好不要一直坐在不动，这样会增加血液的粘性.。要经常站起来走动走动
在飞机是多喝水，少吃东西。吃的太多会导致胃疼或者昏昏欲睡而导致不活动
不要吃安眠药，尽量调整睡眠习惯来适应时常

请问DVT是什么？

DVT - deep vein thrombosis (深静脉血栓)

其实小爱的理解也不错，因为坐飞机的辐射比普通x 光要强很多，这对刚刚受孕的胎儿是不好的，如果因辐射引起胎儿基因突变，是很容易引起畸形儿和流产的。
