Medical documentation after a missed flight

You were ill, you missed the flight, and now the airline's claim form is asking for "suitable medical documentation" — in English, signed by a doctor, within a deadline. The plane is gone, you feel unwell, and the paperwork suddenly matters as much as the illness did.

Take a breath. This page explains what medical documentation after a missed flight can realistically do, who actually decides whether to accept it, and how to get a legitimate document if one is appropriate in your case.

First: who decides whether a note counts

This is the part many travellers discover too late: no doctor can guarantee that a medical note will be accepted. The decision belongs entirely to the airline, the travel insurer, or the booking platform — each has its own requirements.

• Airlines decide whether you qualify for a refund, a rebooking fee waiver, or a voucher. Some require a specific form completed by a doctor; others accept a simple letter.
• Travel insurers decide whether a trip interruption or delay claim is paid. They usually ask for proof that you were medically unfit to travel on that specific date.
• The EU passenger-rights framework (Regulation 261/2004) generally treats denial of boarding on medical grounds differently from ordinary delays — but it is the carrier's assessment that counts, and compensation is not automatic.

So the realistic goal is not "a note that works" but "an honest, well-documented medical record that the airline or insurer can evaluate". A genuine assessment, clearly documented, gives your claim its best chance.

What a doctor can and cannot provide

After a genuine evaluation, a doctor may document what they actually found and, where clinically appropriate, issue a certificate stating that you were unfit to fly at that time. What a responsible doctor will not do is backdate an assessment they never made, state that a specific airline "will accept" the document, or promise an outcome on your claim.

A useful medical note typically states:

• The date and time of the assessment (close to the missed travel date).
• That an evaluation took place and its general findings, in plain terms.
• Whether you were fit to fly on that date — not a diagnosis you did not ask for.

How to get assessed quickly in Spain

If you are a tourist or expat in Spain and cannot face a Spanish-language walk-in clinic while unwell, a video consultation is often the fastest route. You describe what happened, the doctor evaluates you in your own language, and if the clinical picture supports it, documentation can follow the same day in most cases.

Before the consultation, gather:

• Your booking reference and the exact flight details.
• The airline's or insurer's stated documentation requirements, if you have them in writing.
• Any pharmacy receipts or prior consultations related to the illness.

If you are still unwell

Documentation can wait a few hours; your health cannot. Call 112, or go to a local urgent care service or emergency department, if you have chest pain, severe breathing difficulty, signs of dehydration, a high fever that will not come down, or anything that feels like more than the illness that kept you grounded. Emergencies are handled in person, always.

One honest caveat

Some claims are refused even with excellent documentation — because the deadline passed, because the fare rules do not allow it, or because the insurer deems the illness insufficient. A medical certificate is evidence, not a verdict. If a claim is refused, the airline's own complaints procedure and the national enforcement body for air passenger rights are the next steps, not a stronger letter from a doctor.

If you are in Spain and need an assessment after missing a flight, a video consultation with an English-speaking GP can evaluate you and, where clinically appropriate, provide the documentation to support your claim.
