Iberia does not write its own pregnancy limits. It adopts the IATA Medical Manual's recommendation, no flying from 36 weeks or from 32 with an uncomplicated multiple pregnancy, and adds one requirement of its own: from week 28, a certificate from your doctor, presented when you board.
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.

Before 28 weeks Iberia asks for nothing. From week 28 you must present a certificate from your doctor when you board. Iberia follows the IATA Medical Manual, which recommends not flying from 36 weeks with one baby or from 32 with uncomplicated multiples, so your last Iberia flight falls in week 35 (35 weeks + 6 days) or week 31 (31 weeks + 6 days); no certificate changes that.
Most airlines state pregnancy limits as their own rules. Iberia's page instead says the IATA Medical Manual recommends a certificate after 28 weeks and no flying from 36 weeks of gestation (32 for a multiple pregnancy without complications), and that Iberia applies those recommendations. The effect is identical, but the framing tells you two things: the numbers will not move without an industry-wide change, and Iberia adds nothing stricter beyond its one hard requirement, a doctor's certificate at boarding from week 28.
Not from 36 weeks and to the end of week 35 are the same boundary. The first day you cannot fly is 36 weeks + 0 days, the last you can is 35 weeks + 6 days. With uncomplicated multiples, the first excluded day is 32 weeks + 0 days, so the last flight is at 31 weeks + 6 days.
Count every flight on its own date: an eight-day holiday from 34 weeks + 5 days lands you home at 35 weeks + 6 days; nine days is one too many.
Iberia says only a certificate from your doctor, presented when boarding: no form, contents or age rule. Use the UK CAA's standard: confirmation after 28 weeks that the pregnancy is progressing normally without complications, plus the expected date of delivery and fitness to fly on the dates of both flights. Signed by a licensed doctor close to departure, it satisfies Iberia and its neighbours.
A doctor on Mobi Doctor can issue such a pregnancy fit-to-fly certificate where clinically appropriate: you reach a doctor by video usually within 15 minutes, from wherever you are in the EU, then the signed document is emailed; €54 + €10 for the certificate.

Twins and triplets: the IATA figure Iberia applies is 32 weeks, so your last flight is at 31 weeks + 6 days, with the certificate from week 28 as usual. Note the qualifier, without complications: a complicated pregnancy is outside the figures on the page, and Iberia gives no alternative rule, so contact the airline and let the doctor decide.
After the birth, Iberia's page says you will be able to fly again one week later. That is a minimum; the newborn's ticket is a separate matter for the airline.
Not quite, though both are in the same group and share the week-28 and week-36 (32) boundaries. Iberia's page itself notes that at 36 weeks you cannot travel on Vueling-operated flights, but Vueling is far more specific about the document: it wants the original medical authorisation with a validity period, the doctor's medical board number plus a signature. A certificate written for Iberia may not tick those boxes, so if Vueling operates any leg, write it to Vueling's standard. The pregnancy fit-to-fly guide covers what to include.
Within IAG the three carriers differ on the last week. British Airways takes a single pregnancy through week 36 and twins through week 32, but insists on its own pregnancy form or a stamped letter from week 28. Aer Lingus stops at week 35 for European flights, like Iberia, and at week 33 across the Atlantic, with its own Expectant Mother Travel Advice Form and no twins figure. A connection through London or Dublin follows the strictest of the three; the airline pregnancy rules hub compares all 30.
Yes, from week 28: Iberia requires a certificate from your doctor, presented when you board. Before 28 weeks no authorisation is required. Carry it for every flight, including the return.
Until 35 weeks + 6 days if you are carrying one baby, or 31 weeks + 6 days for uncomplicated multiples; Iberia applies IATA's advice not to fly from 36 weeks (32 for multiples).
No. From 36 weeks + 0 days Iberia, following IATA, will not carry you, and a certificate does not change that. Rebook the flight for 35 weeks + 6 days or earlier.
Iberia gives no expiry. Ask for the most recent date practical, stating fitness to fly on both flight dates; several airlines cap letters at 6 to 14 days, so fresh is safest.
No. Unlike British Airways, Ryanair or Aer Lingus, Iberia publishes no template; any doctor's certificate confirming an uncomplicated pregnancy, giving your due date and stating fitness to fly will do.
Iberia's page says when boarding, so keep it in your hand luggage rather than checked baggage. Staff may also ask at check-in; there is no downside to showing it twice.
General information, not medical advice — always confirm with your airline before you travel.
