Aer Lingus sets its pregnancy rules by route, not by how many babies you carry. In Europe you fly to the end of week 35 with the Expectant Mother Travel Advice Form from week 28; transatlantic, the line falls at week 33 and clearance goes through special assistance.
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.
On a European Aer Lingus flight you need nothing until week 27 ends; from week 28 until 35 weeks + 6 days (the end of week 35) your doctor completes the Expectant Mother Travel Advice Form, shown if asked; from week 36 you cannot fly. Transatlantic, the paperwork stage is weeks 28–33 with special assistance clearance, and from week 34 travel is not permitted.
Most carriers split pregnancy rules by single or multiple pregnancy; Aer Lingus splits them by destination: one timetable for European flights, another for transatlantic. Paperwork starts at week 28 in both, but the last permitted week is 35 in Europe and 33 across the Atlantic, so one passenger can be cleared for Dublin–Paris and refused for Dublin–Boston.
For weeks 28–33 transatlantic, the page sends passengers starting in North America to its North American special assistance team for clearance; flying west from Ireland, ask Aer Lingus which process applies.

| Last week, twins or more | Not published; ask the airline |
| Letter must be issued within | Not published |
| Own form | Yes: Expectant Mother Travel Advice Form, completed by your doctor |

It is Aer Lingus's own document: between weeks 28 and 35 your doctor must complete it, and if asked you must present it at check-in and/or the boarding gate. If asked does not mean optional.
The page neither reproduces its questions nor says how recent it must be; expect the usual ground (due date, an uncomplicated pregnancy, fitness to fly; see the pregnancy fit-to-fly guide), which the UK CAA describes as the standard content after 28 weeks, and have it completed close to departure. Whether a letter is accepted instead is not stated.
Europe first: the form band is weeks 28 to 35 and the refusal line is week 36 or over, so the last day you can board a European Aer Lingus flight is 35 weeks + 6 days; one day later you cannot travel, form or not. Transatlantic: clearance covers weeks 28 to 33, and from week 34 you cannot travel, so the last day is 33 weeks + 6 days.
Each flight is tested on its own date: leave at 34 weeks + 6 days and a seven-day holiday returns you on the last permitted day.
Aer Lingus publishes nothing: its page divides passengers by route and week, never by number of babies, so there is no twins figure and no complications rule. Airlines that publish a multiples limit set it earlier (British Airways and Ryanair 32 weeks, Jet2 33), and the RCOG puts uncomplicated twins' ceiling at 32 weeks. Ask Aer Lingus before booking, use the RCOG figure meanwhile, and tell the doctor completing the form it is a multiple pregnancy; complications are recorded on the form too.
The page says your doctor must complete it; midwives are not mentioned. No airline requires a UK GP, nor does Aer Lingus want an Irish one. Take the form to any antenatal appointment first; otherwise book a video consultation: wherever you are in the EU, a doctor on Mobi Doctor comes on video usually within 15 minutes and, where clinically appropriate, issues a signed pregnancy fit-to-fly certificate confirming the points above, emailed after the consultation. Ask Aer Lingus whether it accepts that in place of its form. Cost: €54 + €10 for the certificate.
Ryanair also demands its own form from week 28, completed by a midwife or doctor, but lets a single pregnancy fly to the end of week 36 and publishes a twins limit of 32. British Airways wants a stamped letter or its own pregnancy form from week 28 and allows travel through week 36, twins through 32. easyJet asks for no paperwork and shares Aer Lingus's week-35 line, twins to 32. Transatlantic, Aer Lingus's week-33 limit is three weeks earlier than BA's. The airline pregnancy rules hub shows all 30.
From week 28, yes: on European flights your doctor completes the Expectant Mother Travel Advice Form, shown at check-in or the gate if asked; transatlantic, weeks 28–33 need special assistance clearance.
In Europe, until 35 weeks + 6 days (the end of week 35); across the Atlantic, until 33 weeks + 6 days. Both apply to each flight, including the return.
No. The page states that at week 36 or over you cannot travel on Aer Lingus flights, and on transatlantic routes the refusal starts at week 34. No form overrides either limit.
Aer Lingus publishes no separate limit for a multiple pregnancy. Ask the airline, treat the RCOG's 32 weeks as your ceiling, and tell the doctor completing the form it is a twin pregnancy.
The page gives no maximum age. Complete it close to departure and check it still fits your situation on the return date; a fresh form for the way home is prudent.
You will not be carried: 36 weeks + 0 days in Europe, 34 weeks + 0 days transatlantic, judged on the day of the flight. Move the return earlier; the form cannot extend the limit.
General information, not medical advice — always confirm with your airline before you travel.
