Last-minute cancellation: obtaining a medical certificate within 24 h

Travel cancellationUpdated 17 June 2026

When a health problem strikes a few days — or a few hours — before departure, every hour counts. Between your insurer's declaration deadlines and your ticket's conditions, reacting quickly and in the right order can make the difference between an accepted claim and lost money. Here is how to obtain a medical cancellation certificate quickly and secure your steps.

Why time works against you

Cancellation insurance contracts almost always require you to report the claim very quickly after the medical event occurs, often within just a few days. The airline, for its part, applies the conditions of your ticket, which become less favourable as the departure date approaches. Acting early gives you the most options.

A medical certificate issued on the date the problem arises is also stronger than a document drafted afterwards. The longer you wait, the harder it becomes to present a consistent and admissible file.

Getting a certificate quickly, step by step

The online process is designed to be fast. You describe your situation, a doctor registered with the medical board carries out the assessment remotely, by phone or WhatsApp, then drafts the certificate factually, without revealing your diagnosis. With Certi-Fly, the certificate is generally issued within 24 h.

If your departure is very close, an express option allows accelerated handling. In all cases, the document includes the wording usually expected by insurers and airlines, which helps your file move forward.

Imminent flight: what to do when only hours remain

If your flight leaves the same day, the priority is to trigger the steps in parallel rather than one after another. Notify your insurer and the airline immediately so you do not miss a deadline, then start the certificate request without delay: the express option is the most suitable when time is short.

Keep a written, time-stamped record of every action: declaration to the insurer, exchange with the airline, certificate request. This evidence matters as much as the certificate itself if the question of deadlines comes up.

What a fast certificate does not change

Obtaining a certificate within hours speeds up your file, but on its own it does not guarantee a refund: the final decision always rests with your airline and your insurer, according to the conditions of your contract. Speed helps you meet the deadlines, not bypass the rules of your policy.

A certificate is issued only if the situation justifies it medically, following the assessment. That is precisely what makes it an admissible document, and not a mere form.

Frequently asked questions

Can I get a certificate at the weekend?

The request is made online at any time, weekends included. The timing depends on completing the remote medical assessment; there is no absolute time guarantee, but handling is generally fast, and an express option exists when departure is imminent.

Is a 24 h certificate valid for all insurers?

A certificate signed by a doctor registered with the medical board is an admissible medical document. But each insurer applies its own conditions, exclusions and deadlines: no service can guarantee acceptance by every policy. Always check your contract's requirements.

What should I do if my flight leaves in 12 hours?

Immediately report the situation to your insurer and the airline so you do not miss a deadline, then start the certificate request in parallel — the express option is the most suitable. Keep a time-stamped record of every step.
