Flying while pregnant from Singapore: airline cut-offs, doctor's letters and staying safe in the air

Flying while pregnant is generally safe in an uncomplicated pregnancy, SingHealth says, before 36 weeks with one baby or 32 weeks with twins. Many women find the second trimester the most comfortable time to fly. Airlines set their own limits: Singapore Airlines and Scoot need a doctor's certificate after 28 weeks, dated within 10 days of the first flight after 28 weeks, and won't fly you after 36 weeks. Count the weeks on your return date, not just your departure. On any flight over four hours, SingHealth warns the risk of blood clots goes up, so walk the aisle, flex your ankles, drink plenty of water and wear compression stockings. Check with your doctor before booking, and make sure your travel insurance covers pregnancy problems abroad.

Is it safe to fly while pregnant?

SingHealth's advice is that commercial air travel poses no special risk to an uncomplicated pregnancy. It says air travel before 36 weeks, or 32 weeks if you're carrying twins, is generally considered safe, and that international travel may be cut off after 32 weeks. Flying doesn't cause miscarriage: SingHealth lists travel among the things that do not cause one.

Ask your doctor first if your pregnancy has complications, if you've had bleeding, or if you're at risk of early labour. Your obstetrician knows your history and can tell you if a particular trip is a bad idea.

Airline cut-offs for flights from Changi

These rules are from each airline's own pregnancy page, read on 11 October 2026. Rules change, so check again when you book and a week before you fly.

Jetstar Asia, the Singapore-based Jetstar airline, stopped flying on 31 July 2025, so older lists that mention it are out of date. We couldn't confirm current rules for Malaysia Airlines, Garuda Indonesia, Cebu Pacific, Batik Air or VietJet on their own websites, so check with them directly.

Singapore Airlines and Scoot also say you'll need a certificate for your return flight if it falls after 28 weeks, even if you flew out earlier without one. Singapore Airlines doesn't seat pregnant passengers in emergency exit rows. Several airlines, including Qantas, Cathay Pacific and Emirates, warn that some countries limit entry for pregnant non-nationals, so check your destination's rules too.

The doctor's letter: what it needs to say

Airlines want a recent letter that says you're fit to fly. Singapore Airlines asks for a certificate stating that you're fit to travel, how many weeks pregnant you are and your estimated delivery date. Cathay Pacific wants the same in English, plus whether it's a single or multiple pregnancy. Emirates asks for the latest date your doctor expects you to be fit to travel.

Check how recent the letter must be. Singapore Airlines, Scoot and Cathay want the letter dated within 10 days of the relevant flight, Thai within 7 days, and AirAsia within 30 days. Book the appointment with your gynae or polyclinic for the week before you fly, and ask for two copies if your return also falls after 28 weeks. Our guide to prenatal check-ups and scans shows where a pre-trip review fits into your usual schedule.

Staying safe on the flight

SingHealth's precautions for any flight while pregnant:

• Walk along the aisle regularly. SGH's travel clinic suggests getting up every hour or two, and booking an aisle seat makes this easier.
• If you have to stay seated, flex and stretch your ankles every so often.
• Drink plenty of fluids.
• Wear graduated compression stockings, especially on flights over four hours.

SGH's specialists list pregnancy itself as a risk factor for deep vein thrombosis (DVT), a blood clot in the leg. SingHealth says flights longer than four hours raise the risk of clots in the legs and lungs, so a direct flight to a nearby destination is easier on your body than a long-haul trip. In a car or taxi at either end, SingHealth says to wear a three-point seat belt with one strap above and one below your bump, never across it.

Zika and where you're going

HealthHub says Zika infection in pregnancy can cause microcephaly, an abnormally small head, in a small number of unborn babies, and that pregnant women should take strict precautions against mosquito bites. MOH's advice is that prevention is the best protection for both mother and baby. Check whether your destination has a current Zika or other mosquito-borne disease advisory before you book, and ask your doctor; our guide to Zika and dengue in pregnancy covers safe repellents and testing. HealthHub suggests seeing a doctor four to six weeks before you travel if you might need vaccines.

If you get a fever and rash, red eyes or joint pain after a trip, HealthHub says pregnant women should get medical attention immediately and see their O&G.

Travel insurance and other checks before you book

HealthHub says adequate travel insurance cuts the stress of emergencies, injuries or cancelled flights. For pregnancy, the important line is whether your policy covers pregnancy complications and early labour abroad, and up to which week. Cathay Pacific and Emirates both tell pregnant passengers to get insurance that covers pregnancy problems, and Emirates names preterm labour abroad. Read the policy wording before you buy, since cover often stops at a set number of weeks.

A short checklist:

• Ask your doctor if the trip suits your pregnancy, and when.
• Work out how many weeks pregnant you'll be on the return flight. Our pregnancy week-by-week guide helps.
• Book the doctor's letter for the right dates if you'll be past 28 weeks.
• Pack your antenatal records, any medicines in your hand luggage, and your gynae's contact details.
• Note the nearest hospital with maternity care at your destination.

Frequently asked questions

Until how many weeks can you fly when pregnant?

Most airlines flying from Singapore carry you until the end of 36 weeks with one baby and 32 weeks with twins, as long as you have a doctor's certificate after 28 weeks. Thai Airways stops at 34 weeks on flights over four hours, and Emirates from the 37th week. SingHealth says air travel before 36 weeks is generally considered safe in an uncomplicated pregnancy.

Do I need a doctor's letter to fly while pregnant?

Usually not before 28 weeks. After that, Singapore Airlines, Scoot, Cathay Pacific, Thai, Emirates, AirAsia, Jetstar and Qantas all ask for a certificate, and each has its own validity window, from 7 to 30 days. AirAsia also asks every pregnant passenger to sign a form at check-in.

Is it safe to fly in the first trimester?

SingHealth says air travel poses no special risk to an uncomplicated pregnancy and lists travel among things that don't cause miscarriage. Nausea and tiredness can make flying uncomfortable, so many women prefer to wait for the second trimester.

Do airport scanners harm the baby?

Singapore's health pages don't address airport security scanners. If you're worried, ask for a manual check, and ask your doctor at your next visit.

How do I prevent blood clots when flying pregnant?

Walk the aisle every hour or two, flex your ankles while seated, drink plenty of fluids and wear graduated compression stockings, SingHealth and SGH advise. Book an aisle seat and choose shorter or direct flights where you can.

Can I fly with twins?

Yes, but the cut-off is earlier. SingHealth says air travel is generally considered safe before 32 weeks with twins, and most airlines stop carrying you after the end of 32 weeks.
