Enter your due date, your flights and your airline. You'll see how many weeks pregnant you'll be on each flight, whether the airline will let you board, and whether you need a fit-to-fly letter.
Airline rules decide whether you can board. Your midwife or doctor decides whether it's safe for you. Talk to them first if you've had complications, or if you're flying long-haul. The NHS says the chance of going into labour is naturally higher from 37 weeks (32 weeks with twins).
Check that your travel insurance covers pregnancy, including the birth of a baby abroad. Many policies stop cover at a set week.
Airlines word their limits as "up to the end of week 36". This checker counts 36 weeks + 6 days as the last day. Flights in the final week before a limit are flagged so you can confirm with the airline.
