The second tip would be to avoid flying altogether if you have a difficult pregnancy. You should probably avoid traveling as well, however there might be some trips that cannot be avoided or delayed. If you must travel by all means, you should consider any other ways of doing so, even if it lasts for longer as to reduce all risks.
All pregnant women should get a final check-up before the departure time. At the same time, they should ask for the name of a good doctor or midwife at the destination point. Leaving for a really small town will reduce all options, and you might have to consult with whoever is available there. It might be best to have another check-up after reaching your destination as well.
Before booking any flight, pregnant women should also check out the airline’s rules regarding this aspect as not all of them have the same restrictions. Additionally, the regulations regarding pregnancies will also contain a set of guidelines that should be considered. If you make it safely on the plane, make sure to seek maximum comfort. Aisle seats are the ones recommended to pregnant ladies. Usually the air in the cabin is dry, therefore drinking a lot of water is indicated and not only to the future mothers.
Additionally, if you’re a flight attendant you might want to discuss about your worries with your superiors. You might want more hours on ground, or even a transfer to a different department until after you give birth and are able to resume work.
The last thing you should do is to research as much as possible on experiences of other women who traveled by air at various stages during their pregnancies. The more of these you read the more prepared you are for your own flight. You will be better prepared and you will be able to stop worrying regarding some aspects.
