Fit to Fly Letters: What are they and do you need one?

A Fit to Fly letter (or certificate) is a written statement confirming you’re medically cleared to travel. It is an airline's responsibility to ensure that all passengers are fit to fly, so they or the destinations you go to may request a Fit to Fly letter, especially if you have underlying health concerns.

Understanding when you need a Fit to Fly letter can save you time, stress, and unexpected travel disruptions.

Travelling with a medical condition

If you are pregnant, have a chronic illness, have recently experienced illness, hospitalisation, injury or surgery, or if you need to use medical equipment or therapeutic oxygen on-board, airlines may require a Fit to Fly letter (also known as a Fit to Fly certificate) to confirm that you are healthy enough to travel.

Don’t forget about repatriation cover which is important too.

Pregnancy and air travel

Many airlines require pregnant passengers beyond a certain gestational period to provide a Fit to Fly letter from their doctor or midwife. This document confirms the passenger is fit for travel and helps reduce the risk of in-flight complications. Generally, a Fit to Fly letter is needed after 28 weeks of pregnancy, though airline policies can vary, so always check in advance.

Mental Health

Certain mental health conditions may also require a Fit to Fly letter, especially if they could impact your ability to travel safely. Airlines may request medical clearance to ensure the safety and well-being of both the passenger and others on board. If you are unsure whether you need one, speak to your GP or mental health professional before booking your ticket.

Airline-specific requirements

Each airline has its own policies regarding a Fit to Fly letter or certificate. It’s best to contact the airline’s special assistance team before booking. While you can arrange this after booking, there is a risk of being denied boarding if your healthcare provider does not consider you fit to fly or if the correct paperwork is not provided.
