Pick your situation and your airline — get the answer in seconds, with week-by-week rules verified against official policies (easyJet, Ryanair, British Airways, Wizz Air, Turkish Airlines and more). Need the letter? An EU-licensed doctor can issue it online, usually same-day.
Choose a situation to see whether you need documentation.
Most European airlines require a doctor's or midwife's fit-to-fly letter from week 28 of pregnancy and stop carrying passengers after week 36 (32 for twins) — but policies genuinely differ: easyJet requires no certificate for an uncomplicated pregnancy, Wizz Air wants the letter issued within 6 days of your flight, Turkish Airlines within 10. Outside pregnancy, airlines ask for medical clearance after recent surgery (typically ~10 days for abdominal surgery per CAA guidance), fresh casts, cardiac events and infectious illness. The checker above gives your airline's verified rule with its official source.
See whether your airline requires a certificate for your situation, with the exact week thresholds where published.
A doctor reviews your details and, where clinically appropriate, issues your fit-to-fly letter online — usually the same day.
Your letter states everything airlines ask for, carries a verification reference, and covers outbound and return.

Most European airlines require a doctor's or midwife's letter from week 28 of pregnancy, and stop carrying passengers after the end of week 36 (single) or 32 (multiple). Policies differ — easyJet requires no certificate for uncomplicated pregnancies — so always check your airline's official rule, which this tool links for every verified airline.
Yes, where clinically appropriate. A MobiDoctor doctor assesses you by video, reviews your records (for pregnancy: due date, singleton or multiple, absence of complications) and issues a signed letter with a verification reference that airline staff can check.
As close to travel as practical. Some airlines (e.g. British Airways) explicitly ask for the paperwork to be dated close to the departure date and to cover both legs of the trip.
The tool then shows the typical European pattern (certificate from week 28; last flight at 36/32) and links you to your airline's own medical page. Our letters are written to satisfy standard airline requirements regardless of carrier.
