Air travel is more common now than ever before. However, airline rules are changing, and doctors have new advice about flying during pregnancy. Some airlines may require a note from your doctor if you're far along in your pregnancy.

This guide will help you understand everything you need to know about flying while pregnant in 2025. You'll learn about airline rules, how to make your trip more comfortable, when to talk to your doctor, and what health experts recommend.
This guide provides simple, clear information whether you're early in your pregnancy or nearing your due date. That way, you can feel calm and confident when you fly, knowing you’re doing what’s best for you and your baby.
Understanding Pregnancy and Air Travel
Flying during pregnancy is generally safe for most individuals, but understanding what to expect at various stages is crucial. Each part of pregnancy — called a trimester — comes with other changes in the body. Knowing when travel is safest and most comfortable can help you plan better.
Many pregnant women feel tired or sick in the first trimester (weeks 1–12). Some may worry about miscarriage, but flying does not cause it. Still, the early weeks can be tough, and flying might not feel comfortable.
The second trimester (weeks 13–27) is often the best time to fly. Morning sickness usually improves, energy levels increase, and the baby bump isn’t too big yet. This is when most doctors say it’s safe and easiest to travel.
The body prepares for birth during the third trimester (weeks 28–40). It may be harder to sit for long hours, and there’s a slight chance of going into labour early. Some airlines may ask for a letter from your doctor after 28 weeks and might not let you fly after 36 weeks (or 32 weeks if you have twins). Always check the airline’s rules before booking.
There are also some myths about flying while pregnant, like the idea that the air pressure on planes can hurt the baby or cause early labour. These things aren’t true. Plane cabins are pressurised and safe.
But there are real risks to think about. One is blood clots, also known as deep vein thrombosis (DVT). This can happen if you sit still for a long time. You can lower the risk by walking around during the flight, drinking plenty of water, and wearing special socks called compression stockings.
Health experts, such as the World Health Organization (WHO) and the American College of Obstetricians and Gynecologists (ACOG), say that flying during a healthy pregnancy is safe, especially in the second trimester.
Most importantly, always talk to your doctor or midwife before flying. They can tell you if it’s okay for you to travel and give you tips to stay safe and comfortable.
In short, flying while pregnant is usually fine — just plan carefully, know the best time to go, and get advice from your healthcare provider.
Airline Policies in 2025: What You Need to Know
General Airline Rules
If you're pregnant and considering flying in 2025, you should know some essential rules. Most airlines allow pregnant people to fly, but limits depend on how far along you are.
When is it too late to fly?
- Most airlines let you fly for 36 weeks if you have one baby.
- You can usually fly until 32 weeks if you have twins or more.
After that, airlines may not let you fly because there's a higher chance of going into labour.
What is a “fit-to-fly” letter?
Most airlines ask for a letter from your doctor or midwife after 28 weeks of pregnancy. This letter should say:
- You’re healthy and okay to fly
- Your due date
- Your pregnancy has no problems
Short flights vs. long flights:
- Short flights (less than 4 hours) are usually easier and more comfortable.
- Long flights (more than 4 hours) may raise your risk of blood clots, so moving around, drinking water, and wearing special socks is essential.
Travelling in your country vs. going abroad:
- Domestic flights (within your country) often have more straightforward rules.
- International flights can be stricter, and some countries have rules about pregnant travellers.
Some airlines may ask for this letter earlier, like at 24 weeks, so check before you book your flight. Here’s an example from a UK service: MyHealthWorks Fit-to-Fly Letter

- Use compression socks: These help stop your legs from swelling.
- Drink lots of water: Planes are dry, and staying hydrated helps you feel better.
- Bring snacks: Healthy snacks keep your energy up.
- Move around: Walk down the aisle every hour and stretch your legs.
Looking After Your Health
- Nausea: Ginger sweets or wristbands may help.
- Swelling: Don’t cross your legs and try to lift your feet sometimes.
- Tiredness: Get good rest before your flight and bring a neck pillow.
- Tell the flight crew you’re pregnant if you need help.

With good planning and the proper support, flying during pregnancy in 2025 can be safe, calm, and enjoyable. Always talk to your doctor and check airline rules before your trip.
Legal, Insurance & Travel Documents
Travel Insurance While Pregnant
When you're pregnant and planning a trip, travel insurance is essential. This helps cover the cost if something goes wrong while you're away.
What’s usually covered:
- Help if you have an unexpected pregnancy problem (like early contractions or bleeding).
- Emergency medical transport to the hospital.
- Getting money back if you have to cancel your trip because of a pregnancy issue, your doctor warns you about.
What’s usually not covered:
- Regular check-ups or baby scans while on holiday.
- Giving birth during your trip (planned or unplanned).
- Flying after 28–32 weeks (most insurance stops covering you now).
Tip: Always read your insurance policy carefully. In 2025, some companies, like Admiral and Holidaysafe, will offer special insurance just for pregnant travellers.
Countries with Special Rules
Some countries have special rules for pregnant travellers. You might need a doctor’s letter saying you’re healthy and fit to travel — especially if you’re over 28 weeks pregnant. Airlines like Emirates and SAS will ask for this.
Even in 2025, some COVID-19 rules are still in place. A few countries may ask for a health form or proof that you’ve had certain vaccines. For example, South Korea requires a " Q-Code " form if you’re coming from some countries. Read more from the US Embassy. Always check the latest rules for the country you visit before you go.
Extra Documents to Bring
To make your trip easier, pack these crucial papers:
- Your pregnancy records: These include your check-up notes. Bring a translated copy if you’re going to a country where people don’t speak English.
- Fit to Fly letter: Many airlines want this after 28 weeks. It says you're safe to fly and gives your due date.
- Your passport and visa: Ensure your passport is still good for at least six more months. Some countries have extra rules if you’re close to giving birth, so check early.
Keep these papers in your carry-on bag so they’re easily accessible at the airport or during your flight.
Being organised with the right insurance and documents means a safer, more leisurely trip, and more time to relax and enjoy your travels before the baby arrives.
