Most international airlines allow uncomplicated singleton pregnancies through 34 to 36 weeks, but the number is not the whole rule. Wizz Air stops after week 34, AirAsia after week 35, and many long-haul carriers after week 36, with Emirates requiring special permission beyond that point.
The paperwork can fail you first: fit-to-fly letters often need to be issued within 6 to 10 days of travel, digital check-in may not accept them, and on code-shares the operating airline’s stricter policy can apply without warning.
Ask a traveler what the cutoff is and they will quote a week number. Ask a gate agent why someone was refused boarding and the answer usually comes down to a document date, an unclear calculation, or a code-share nobody checked.
Take Wizz Air: no singleton past week 34, and from week 28 the Fit-to-Fly form must be issued within six days of the flight. That is tighter than nearly any other major carrier.
Cathay Pacific gives you ten days from the first outbound travel date for certificates between weeks 28 and 36. AirAsia allows certificates dated up to 30 days before travel — a relaxed standard that stops helping the moment your ticket includes a partner with a six-day rule. The week limit is only the top layer.
This guide reads the policies behind the number: where carriers actually diverge, why the same week count can fail at two different airports, and what to do before check-in to avoid arguing with a supervisor at 23:00.
Where each airline draws the line
Most international carriers cluster around a common skeleton: no documentation before week 28 for an uncomplicated single pregnancy, a medical certificate from roughly week 28 or 29, and a hard stop at or near week 36. Multiples and higher-risk pregnancies lose roughly four weeks off the back end.
The exceptions change real itineraries: AirAsia requires a doctor’s certificate between weeks 28 and 34 inclusive, then sets a complete ban at 35 weeks and above. Wizz Air bars singleton travel after 34 weeks and multiples after 32 weeks. Neither carrier defines whether the prohibition starts at the beginning of the final week or at its close.
The full-service network is more predictable but still uneven. Cathay Pacific and Singapore Airlines both need a certificate from week 28 or 29 and stop at 36 weeks. Cathay defines its cutoff as 35 weeks plus seven days.
British Airways accepts singletons through the end of week 36 and multiples through week 32, with its form or an official letter from week 28. Emirates starts earlier — a certificate from week 29 — and bars travel after week 36 without special permission from its medical department.
Flight duration changes the answer on Jetstar and Qantas services. Under four hours, a routine singleton can fly to the end of week 40, but at four hours or more the limit is the end of week 36. Multiples drop to 36 weeks on short sectors and 32 weeks on long ones.
Air India is more conditional: it accepts a healthy singleton up to and including week 35 when normal delivery is anticipated, but stops at week 32 for complicated or multiple pregnancies. One major Indian carrier, IndiGo, could not be verified from an accessible official page, so it stays out of the direct comparison.
Freshness windows are the silent gatekeepers
A certificate that says all the right things is still worthless if it is too old. Wizz Air’s Fit-to-Fly form must be issued within 6 days of the flight date. Cathay Pacific and Singapore Airlines give a 10-day window from the first outbound travel.
AirAsia’s 30-day allowance is the most relaxed of the group, but only on itineraries operated by carriers that accept the same standard. Air India adds another layer: if more than a month passes between booking and departure, the certificate must be dated within three days of travel. The AirAsia India medical form pushes the deadline forward — medical details must be submitted 24 to 48 hours before departure so company doctors can clear the traveler, with no guaranteed review time promised.

Why enforcement stays murky
These rules live in conditions of carriage and special-assistance pages, not on the boarding pass. The wording itself becomes the enforcement tool, and not every airline defines its week the same way. Cathay Pacific spells out that “after the 36th week” is 35 weeks plus seven days, while most others use looser phrases like “after week 34” or “35 weeks and above.”
Digital check-in rarely helps. Jetstar and Qantas require documentation from week 28 but never outline an online upload path, so the certificate has to surface at the airport counter. Code-share itineraries are even looser: no public policy reviewed here states that the operating carrier’s pregnancy rule always overrides the marketing carrier’s.
There is no verified public case of a traveler being denied solely because of a miscalculated week, an expired certificate or a code-share mismatch. The risk sits in the structure of the policies, not in a documented precedent.
How to protect yourself at the gate
The safest strategy is to treat the strictest carrier on your ticket as the one that matters.
- Time the certificate to the tightest deadline. Wizz Air wants six days; Cathay Pacific and Singapore Airlines want ten; Air India may require three days if a month passed between booking and travel.
- Check the airline operating every segment, and assume its pregnancy limit controls even if another airline appears on the ticket.
- Plan for paper. Most airlines will not accept pregnancy documents through a digital check-in upload, so leave extra time for airport verification.
- If you are flying on AirAsia India or need carrier medical clearance, submit forms 24 to 48 hours before departure rather than waiting until the last evening.
- Count conservatively. If an airline says “after week 34” without defining the day, treat the entire final week as closed.
For a singleton pregnancy on a standard long-haul route, the realistic window is a certificate obtained inside the freshness window and a flight that boards before the end of week 36 — or earlier if Wizz Air, AirAsia or a multiple birth is involved.
Questions? Answers.
How many weeks pregnant can you fly internationally
Most international airlines let women with uncomplicated singleton pregnancies fly through 34 to 36 weeks, but exceptions matter: Wizz Air stops after 34 weeks, AirAsia at 35, Emirates at 36 unless medical permission is granted, and Qantas or Jetstar can allow up to 40 weeks on short sectors under four hours. A fit-to-fly certificate is usually required from week 28 or 29.
Can you fly at 8 months pregnant internationally
Eight months is roughly weeks 32 to 35, so many carriers will still accept a singleton pregnancy with a valid certificate. Wizz Air stops after 34 weeks and AirAsia at 35, while Air India permits week 35 only when a normal delivery is anticipated. Multiple or complicated pregnancies are often barred after week 32.
Can you fly at 7 months pregnant internationally
Yes, but this is when documentation usually starts. Most carriers require the first fit-to-fly certificate somewhere between week 28 and week 29; Wizz Air demands its form issued within six days of the flight. Cathay Pacific and Singapore Airlines allow ten days from first outbound travel.
Can I still fly at 32 weeks pregnant
For a singleton pregnancy, yes on most carriers — Wizz Air allows singletons until after week 34, AirAsia until 35, and full-service carriers until around 36. If you are carrying multiples or have a complicated pregnancy, the picture tightens sharply: Air India and many others stop boarding after week 32.
Can you fly at 9 months pregnant
Generally no. Wizz Air stops singleton travel after week 34, AirAsia at 35, and Cathay Pacific, Singapore Airlines, British Airways and Emirates bar it at or after week 36 unless special permission is granted. The main exception is a Qantas or Jetstar flight under four hours, which can allow a singleton through the end of week 40.
How many weeks pregnant can you fly internationally Emirates
Emirates requires a medical certificate signed by a doctor or midwife for any travel during or after the 29th week of pregnancy. Travel after the 36th week is generally not allowed unless you obtain special permission from Emirates’ Medical Department.
