Is it safe to fly while I’m pregnant?
We’ve rounded up all the NHS advice to answer your most asked questions.
Booked a holiday before you knew you were expecting or want to squeeze in a babymoon before your due date? Flying while pregnant is generally considered safe until the 36th week (36+6 week mark). There are a few things to consider before take-off, though, like needing a medical certificate to confirm you’re fit to fly, informing your travel insurance provider and speaking to your doctor or midwife about any vaccinations you might need. To help you travel safely during your pregnancy, we've compiled a list of essential advice from the NHS, including handy tips like booking an extra seat and finding the nearest hospital at your destination. Read on for all the info...
When can I fly?
If you’re feeling well, are low-risk and aren’t facing any complications during your pregnancy, you’ve got some flexibility when it comes to flying.
If you haven’t had any complications during your first 28 weeks of pregnancy, you can fly without a medical certificate.
If you’ve had complications within your first 28 weeks, you’ll need a medical certificate to confirm you’re fit to fly. We’ve listed all the info your medical certificate needs to include below.
Single pregnancies
Multiple pregnancies
Flying with other airlines
If you’re not flying with TUI Airways, please contact the airline you’re flying with as they may have different guidelines on flying while you’re pregnant.

What information must my medical certificate include?
- It must be issued and signed by a doctor or attending midwife
- It needs to have been issued within 14 days of your departure date
- It needs to state if the pregnancy is single or multiple
- It also needs to have the number of weeks of pregnancy and the expected date of delivery
- It must confirm that you’re fit to fly
What about travel insurance?
We recommend getting travel insurance that covers you from the date you book your holiday to the date you arrive home in the UK. Most standard travel insurance policies only cover up to the 28th week of pregnancy, so it's a good idea to double (or triple!) check with your provider. If you find out you’re pregnant after you’ve taken out your insurance, let them know as soon as possible. It’s really important to let them know about any pregnancy-related illnesses or complications.
Should I go on long-haul holidays when pregnant?
Some pregnant people prefer to avoid long-distance travel in the first and third trimesters, purely for their own comfort and peace of mind. Long-distance travel (over 4-5 hours) can also increase the risk of deep vein thrombosis. While the NHS doesn't state that this risk is higher during pregnancy, pregnant people should take extra precautions, such as wearing compression stockings and staying hydrated.
Is there anything I should do on the plane?
Yes. As well as wearing compression stockings, it’s worth thinking about the following:
- Wearing your seatbelt below your bump, rather than above it.
- Drinking plenty of water to stay hydrated, and snacking regularly to keep your energy levels up.
- Getting up as often as you can and doing calf exercises and stretches in your seat.
- Think about reserving your seat in advance so you can make sure you get an aisle seat or one with extra legroom.
- If you’re travelling with a child between 6 months and 2 years, you might want to book them their own seat. A bump and a toddler on your lap might not be a great mix. Plus, if you book them a seat and pop the armrest up, you’ll get some extra space to spread out.
Just so you know, according to policy for all UK-registered aircraft:
- Due to safety regulations, some seats have restrictions for passengers who are pregnant, and you’ll be able to view seat availability and any restrictions on the aircraft seat map when selecting your seat.
- Infants aged under 6 months must sit on an adult’s lap and be secured with an infant lap-strap for the duration of the flight – this will be provided on the plane.
What about airport scanner – could it be harmful to my baby?
Airport scanners use a low-frequency electromagnetic field and are considered safe for everybody, including if you’re pregnant. It’s worth bearing in mind that pregnant people who work airside pass through these scanners every day.
Will an insecticide be sprayed in the cabin during my flight?
The cabin may be sprayed before or after you board, or when you land at certain destinations.

What do I need to know about the Zika virus?
The best place to find out about Zika virus disease and how it affects pregnant people is the Foreign & Commonwealth Office’s official website which explains the precautions you need to take before considering travel. If you’re planning to travel to an area with active Zika virus transmission, you’ll need to talk to your doctor or midwife or obstetrician and may need to postpone your trip.
Can I have vaccinations if I’m pregnant?
If it’s essential that you travel to a destination that requires vaccinations, you’ll need to book an appointment with your midwife or GP to discuss your options. The NHS website has some useful info on the latest recommendations.
Is there anything else I can do to prepare?
Before you go, make sure you know how to get access to help while you’re on holiday. Find out the details of the closest doctor or hospital, confirm your due date and take a copy of your maternity notes or a general medical history with you. This should include your blood type, any medications you’re taking or are allergic to, and your doctor’s details back home. If nothing else, it’ll give you a bit of peace of mind while you’re away.
