Cancelling a Trip Because of a Relative's or Companion's Illness

Travel cancellationUpdated 17 June 2026

A trip is not always cancelled because of your own health. The illness of a loved one, a family member, or the person you were due to travel with can also prevent you from flying. In these situations, travel cancellation insurance may, depending on your policy, cover the costs, and a medical certificate issued by a doctor often plays a central role in the claim.

When Insurance May Cover a Cancellation Linked to a Relative

Most travel cancellation policies provide for situations where the illness of someone other than the insured can justify cancelling. The conditions, however, vary widely depending on the insurer, the policy, and the relationship with the person concerned. It is essential to read your insurance policy to know exactly which cases are covered and what exclusions may apply.

In practice, policies often define who counts as a relative and which events trigger coverage. The illness generally has to be sudden, unforeseeable at the time of booking, and genuinely prevent the trip from going ahead as planned.

The Role of the Medical Certificate in the Claim

When a cancellation is linked to someone's state of health, the insurer almost always requests medical evidence. A certificate issued by a doctor registered with the medical board objectively attests that a medical situation incompatible with going ahead with the trip exists, while respecting medical confidentiality.

The certificate alone does not guarantee compensation: the decision rests with the insurer, who assesses the claim against your policy. It is, however, the central document that ties the cancellation to an admissible medical cause. Certi-Fly issues this certificate after a medical assessment carried out by phone or WhatsApp, with video as an option, and usually delivers it within 24 hours.

The Case of a Companion Who Can No Longer Travel Alone

A common situation involves a traveller who is in good health themselves, but whose companion falls ill and can no longer go. Many policies provide for this case, particularly when the people are travelling together on the same booking and continuing the trip alone would be difficult or even impossible.

This is especially true when the remaining person cannot reasonably travel alone because of their age, a dependency, or because the trip was designed for two. Here again, the rules depend on the policy: some insurers cover all the travellers on a single booking, while others limit coverage. Check your general terms to find out how the cancellation of a companion is handled.

Good Habits for Building Your Claim

The more complete and consistent the claim, the more smoothly the insurer can process it. Act quickly as soon as the medical event occurs: most policies impose a deadline for reporting the cancellation, often very shortly after the event takes place.

Gather your travel documents and the medical certificate, then follow the procedure indicated by your insurer. Certi-Fly focuses solely on issuing the medical cancellation certificate after an assessment by phone or WhatsApp; the decision to compensate remains the insurer's.

Frequently asked questions

Does insurance automatically refund me if a relative falls ill?

No. A refund is never automatic. Coverage depends on your policy, the relationship with the person concerned, whether the illness was unforeseeable, and the supporting documents provided. The insurer assesses the claim. Consult your insurance policy to see which cases are covered.

Is a medical certificate required for this type of cancellation?

In the vast majority of cases, the insurer requests medical evidence when the cancellation is linked to someone's health. A certificate issued by a doctor registered with the medical board after an assessment is the document that ties the cancellation to a medical cause, without disclosing information protected by confidentiality.

My companion is ill but I am in good health: am I covered?

It depends on your policy. Many insurers provide for this case, especially when you were travelling together on a single booking or when you cannot reasonably travel alone. Check your general terms to find out how the cancellation of a companion is handled.

How does Certi-Fly issue the certificate?

Certi-Fly carries out a medical assessment by phone or WhatsApp, with video as an option, then a doctor registered with the medical board issues and signs the certificate, usually delivered within 24 hours. The document is never a template you fill in yourself: it is written and signed by the doctor after the assessment.
