From week 28, British Airways wants its pregnancy form, or an official letter, completed and stamped by your doctor or midwife and shown at check-in. Fly to the end of week 36 with one baby, week 32 with more. A doctor on Mobi Doctor can complete it during a video consultation, and you usually see one within 15 minutes.
Or plan by dates. Enter your due date and flight dates: the planner works out how pregnant you will be on each flight, whether that flight is allowed, whether a letter is needed for each leg, and the dates a letter must be signed between so it is still valid on the way home.
Copy the flight lines from the airline’s confirmation email (flight number, date, times) and paste them here. It is read in your browser; nothing is sent anywhere.
Enter your flight number and the dates above (or a route), and the planner fills in the airline — the operating carrier on a codeshare — and the flight time from the published schedule.
Or by route: to on the outbound date.
Choose a situation to see whether you need documentation.
Yes, from week 28 you need paperwork for British Airways: either BA's Pregnancy Form or an official letter, completed and stamped by a doctor or midwife, dated close to departure and shown at check-in on the day. It confirms an uncomplicated pregnancy, the weeks of gestation and fitness to travel for the whole journey. The limits: the end of week 36, or week 32 with more than one baby.
Two options. The first is BA's own Pregnancy Form, a PDF (30kb, English only) on its medical conditions page. You fill in your name, estimated date of delivery and every flight you are taking, with date, flight number, origin and destination. Your doctor or midwife then confirms a single or a multiple uncomplicated pregnancy, enters the weeks of gestation and certifies you fit to travel for the entire journey.
The second is an official letter saying the same, completed and stamped by your doctor or midwife.
A doctor or a midwife: BA names both and does not restrict you to a GP, so any licensed doctor or midwife will do. The form has a box for the practitioner's stamp as well as the signature; make sure both are there.
Over video, a doctor on Mobi Doctor can complete and sign the medical section where clinically appropriate, daily 7am–11pm CET: you see a doctor usually within 15 minutes, and the signed document is emailed to you afterwards (more on our fit-to-fly certificate page).
BA gives no number of days; it asks for the document to be dated as close to your travel date as possible: in practice, the week you fly out. That is looser than Jet2, which insists on 7 days, or Wizz Air with its 6.
The upside: one form covers the entire journey, outbound and return, provided you need no medical care during the trip. Two caveats: the week limit still applies on the return date, and after medical care abroad the form no longer covers you, so get a fresh letter before flying home.
To the end of week 36 with one baby: your last possible flight is on the day you are 36 weeks + 6 days pregnant, and from the first day of week 37 you cannot fly, however good the form. With more than one baby, week 32.
BA applies the limit to each flight date, so a return in week 37 is refused even if the outbound was in week 35; the RCOG notes that from 37 weeks you could go into labour at any time.
At the airport, to check-in staff, on the day of travel. The form carries that instruction in capitals and the medical conditions page repeats it, so keep the completed original with your passport, not in hold luggage.
This is a lighter check than Ryanair, whose form can be checked at the boarding gate as well as at bag drop, but forgetting it has the same consequence, because BA requires the paperwork from week 28. A photo of the completed form is a backup, not a substitute.
These are BA's published rules on 24 September 2026. On the same routes, easyJet asks for no paperwork but stops a week earlier at 35, Jet2 wants a certificate signed inside 7 days of departure and also stops at 35, and Ryanair matches BA's week-36 limit with a form of its own. A fixed form, no rigid validity window and one document for both legs make BA's rules among the easier ones. Every airline's limit is in our flying while pregnant guide.

Yes, once you reach week 28. British Airways accepts its own Pregnancy Form or an official letter, either one completed and stamped by a doctor or midwife and presented at check-in. Under 28 weeks there is nothing to bring.
Your name, estimated date of delivery and the dates and flight numbers of every leg. The doctor or midwife confirms a single or multiple uncomplicated pregnancy and the weeks of gestation, certifies fitness to travel for the entire journey, then signs, dates and stamps.
Yes. BA's page and the form both name the doctor or midwife, and the form has a signature line for either; it must also be stamped. BA does not require a GP or a practitioner from any particular country.
Yes, with the form or letter, up to the day you are 36 weeks + 6 days pregnant with one baby. From 37 weeks BA will not carry you; the end of week 32 applies with more than one baby.
No. BA's limit for more than one baby is the end of week 32, which makes 33 weeks too late for any leg. Between weeks 28 and 32 you fly with the completed form or stamped letter.
It will be refused, because the limit applies on the date of each flight, not just the outbound. Rebook the return before the end of week 36 (week 32 with more than one baby) and have the new date put on the form.
