Fit to Fly Certificate Online, Reviewed by a Certified Doctor

A fit to fly certificate is a doctor's statement that a passenger's current health will not put them or the flight at risk in the air. The operative line on the document openly confirms that the traveller is medically able to fly on the dates written there.

A fit to fly certificate does not diagnose an illness or treat one.

The certificate also does not oblige an airline to carry you. The UK Civil Aviation Authority explains that most airlines have medical advisors who clear passengers as fit to fly, and that the final decision on carrying a passenger rests with the airline.

People also call it a fit to travel certificate, a fitness to fly letter or medical clearance for air travel.

Airlines usually expect a fit to fly certificate to name the passenger as shown on the passport, state the travel dates and say plainly that the passenger is fit to fly. Employers and schools arranging overseas trips usually want the same basic details.

Rules differ by airline, employer, institution and country.

One carrier may accept a general fit to fly letter, while another asks for its own medical information form, often called a MEDIF, signed by the treating doctor. Airlines also set their own limits on how recently the certificate must be dated.

Before you apply, ask the recipient whether online medical notes are accepted, whether you must use their own form and how recent the certificate date needs to be. Travellers in Singapore and Thailand can find local details on the country pages.

The doctor will ask about your current health, the condition behind the airline's request and the dates that matter, including your flight date and when any surgery, illness or diagnosis happened. Expect questions about current symptoms and any medicines you take.

Supporting documents help. A hospital discharge letter, a recent note from your treating doctor or the airline's message asking for clearance gives useful context, so mention them or share them when asked.

The doctor may ask follow-up questions in the chat before deciding. Answer them accurately, because inconsistent details are a common reason for a decline.

If the doctor cannot issue your fit to fly certificate, you will not receive one and your payment is not refunded. Doctors decline about 2% of requests, usually when the name and ID do not match or when the symptoms and details shared are inconsistent.

An online review cannot replace an examination. A doctor may decline when your condition is unstable, when tests or an in person check are needed, when you had major surgery very recently, or when the airline wants its own form signed by your treating doctor.

The only refund exception is a verified technical fault reported within 24 hours. For help, email care@drcertificate.com.
