When Can I Fly?

It is normally perfectly safe for women to fly whilst pregnant. However, most Airlines restrict travel in the late stages of pregnancy. The current air travel health guidelines for air travel for pregnant women are:

SINGLE PREGNANCY: after 28 weeks a note from the passenger’s Doctor or Mid-wife to confirm that the pregnancy is normal and to verify the expected due date, but flying is usually permissable up to 36 weeks

MULTIPLE PREGNANCY: after 28 weeks a note from the passenger’s Doctor or Mid-wife to confirm that the pregnancy is normal and to verify the expected due date, but flying is usually permissable up to 32weeks

BABIES: it is not advised that any baby under 7 days old travels by air.

Seek advice from a Doctor should air travel be necessary.

 

 

 

What about the risk of a DVT?

Deep Vein Thrombosis, or DVT as it is commonly known, is caused by long periods of immobility, notably on a long-haul flight.

DVT is when the blood clots deep within the veins of the legs causing swelling, stiffness and discomfort.

In most instances, cases of DVT aren’t severe, and mostly occur in passengers who are not in good-health or have recently undergone major heart surgery, are extremely overweight, suffering from certain forms of cancer or have a family history of blood-clotting abnormalities.

The risk of DVT (deep venous thrombosis) is higher in pregnancy and therefore pregnant women should take additional precautions to reduce the risk of DVT, especially on long haul flights.

Any passengers with additional risk factors should seek medical advice from a Doctor well in advance of travel.

Whilst few passengers ever actually suffer from DVT there are steps and health advice when flying that all air travellers can take to help reduce the chances of suffering from DVT:

Move about the cabin every hour or so.

Whilst seated stretch out the legs, in particular the calf muscles, and rotate the ankles.

Drink plenty of water both before and during the flight.

Avoid alcohol and caffeine before and during the flight.

Wear flight socks, also known as compression stockings, during the flight.



RCOG releases updated guidance on air travel during pregnancy

Evidence suggests there is no reason why women with uncomplicated singleton pregnancies should not travel by air. The Royal College of Obstetrics and Gynaecology advises that these women should avoid air travel at 37 weeks of gestation as birth is usually expected at this stage. For women with uncomplicated multiple pregnancies, it is 34 weeks.

Although cabin pressure can result in dehydration, there has been concern it could also lead to a range of conditions such as preterm labour, preterm rupture of the membranes and placental abruption for women in advanced stages of pregnancy (after 32 weeks of gestation). There is no evidence that air travel can lead to these adverse pregnancy outcomes. To prevent dehydration, women should avoid caffeine and alcohol and maintain a good fluid intake during the flight.

The increase in altitude in the plane could result in some discomfort in the ears and nose. Motion sickness (made worse by morning sickness) may also be experienced.

A particular concern is deep venous thrombosis (DVT). The risk of DVT is increased during air travel because of the long periods of immobility and the cramped seating arrangements during medium to long-haul flights (four hours and more). The current advice is for women to wear properly fitted graduated elastic compression stockings during the flight to reduce the risk of DVT.

To help prevent DVT, pregnant women are encouraged to have some physical movement by walking along the aisles every 30mins where possible and by doing some light stretching to increase their blood circulation.

The common risk factors indicating that pregnant women should not travel by air or will need to take special precautions or treatment include:

  • Severe anaemia
  • Recent development of sickle cell crisis
  • Recent obstetric haemorrhage
  • Nephrotic syndrome (a kidney condition)
  • Wearing a cast from a recent fracture in the leg
  • An ear infection (otitis media) and inflammation of the sinuses (sinusitus)
  • Serious respiratory problems marked by breathlessness
  • Recent gastrointestinal surgery
  • Previous DVT (where treatment to prevent recurrent thrombosis is usually required)
  • Severe obesity
  • Professor Ian Greer, from The Hull York Medical School, who produced the Opinion Paper on behalf of the RCOG said “Women should be reassured that commercial air travel is not associated with specific problems in pregnancy, and that with simple precaution those with an uncomplicated singleton pregnancy can travel safely up to 37 weeks.

    “Pregnant women with the particular conditions, or indeed any medical condition that concerns them, should seek specific medical advice before travelling.”

    Professor Steve Thornton, Chair of the RCOG Scientific Advisory Committee, said “One of the most common questions we get from pregnant women is whether or not it is safe to fly when pregnant. This Opinion Paper addresses many of the issues and makes sensible recommendations.

    “Whilst it is generally safe for women with low risk pregnancies to fly, there are increased risks of deep vein thrombosis (DVT). Women unsure about these risks or other medical conditions are advised to speak to their GP, midwife or obstetrician.”
