Flying while pregnant

For most people with a straightforward pregnancy, flying is considered safe — so if you’re dreaming of a “babymoon” or need to travel, you can usually go ahead. There are a few sensible precautions and some timing rules to know, but pregnancy doesn’t have to ground you.

The best window. Many people find the second trimester (roughly weeks 14–27) the easiest time to travel: the early nausea and tiredness have often eased, and you’re not yet at the more uncomfortable, higher-risk late stage. If you have a choice, that middle stretch is often the sweet spot.

Airline cut-off dates. Airlines set their own limits on how late in pregnancy you can fly, and they’re stricter than you might expect — often around 36 weeks for a single baby (earlier for twins), and many require a letter from your doctor or midwife after about 28 weeks confirming your due date and that you’re fit to fly. Always check your specific airline’s policy well before booking, as rules vary.

Blood clots — the main precaution. Pregnancy already raises your risk of blood clots (DVT), and long flights add to it. To reduce the risk on longer trips: move around the cabin regularly, flex and circle your ankles in your seat, stay well hydrated, and wear compression stockings if advised. Ask your midwife or GP whether you need any extra precautions for your situation.

Comfort in the air. Book an aisle seat so you can get up easily (and reach the loo), wear loose, comfy clothing, keep your seatbelt fastened low under your bump, and bring snacks and a water bottle to fill after security. Take your maternity notes/records with you, especially for international travel.

When flying may not be advised. Talk to your midwife or doctor first — and flying may be discouraged — if you have pregnancy complications such as pre-eclampsia, a risk of preterm labour, significant anaemia, placenta problems, or if you’re expecting multiples. If you’ve had any bleeding or other concerns, get individual advice before you travel.

Think about where you’re going. Consider the standard of medical care at your destination, whether your travel insurance covers pregnancy and a possible early birth (many don’t — read the fine print), and any health risks like the Zika virus in certain regions, which is serious in pregnancy. Check current travel and health advice before booking.

Airport security is fine. The walk-through scanners at airport security are safe in pregnancy, so there’s no need to worry about those.

For a healthy, low-risk pregnancy, flying is usually absolutely fine with a bit of planning — the main things are to check your airline’s cut-off, protect against clots on longer flights, and sort appropriate insurance. When in doubt about your own situation, a quick chat with your midwife or GP will set you straight. Enjoy the trip.
