Fit-to-fly certificate in Costa Rica
After an admission, a surgery or a serious injury, the airline and the insurer want a physician to confirm you can fly. Here is what the assessment involves and how fast it can be done.
- A fit-to-fly certificate is a physician's written statement, following IATA medical guidance, that a patient can safely take a commercial flight.
- Airlines may also require their own MEDIF form, signed by the treating physician, for passengers with recent illness or special needs.
- Relevium performs the assessment in San José, usually the same day, and coordinates escorts, oxygen or an air ambulance when a commercial flight is not appropriate.
What the certificate is — and is not
A fit-to-fly (or "fit to travel") letter confirms that, in the physician's judgement, the patient can tolerate a commercial flight: reduced cabin pressure equivalent to about 2,000 m of altitude, lower oxygen, prolonged sitting, limited access to care in the air. It is not a guarantee of health and does not replace the airline's own medical clearance when the carrier requires it.
Airlines generally ask for clearance after recent surgery, hospitalization, a heart or lung event, a fracture in a cast, a pneumothorax, late pregnancy, or when the passenger needs oxygen, a stretcher or a medical escort. Insurers ask for it to authorize repatriation.
What the assessment covers
The physician reviews the diagnosis, the treatment, the current examination and — where relevant — oxygen saturation at rest and on exertion, a recent ECG or imaging, and the risk of deterioration in flight. Common thresholds used in practice: uncomplicated heart attack, usually 7–10 days; abdominal or laparoscopic surgery, around 10 days; pneumothorax, at least 7 days after full re-expansion confirmed on imaging; a fresh cast may need to be split for long flights. Each case is individual.
The outcome is one of three: cleared; cleared with special assistance (wheelchair, extra seating for a leg in extension, in-flight oxygen, a nurse or physician escort); or not yet fit, with a date to reassess.
MEDIF and airline forms
Most airlines use the IATA MEDIF form (Medical Information Form), part of which is completed by the passenger and part by the treating physician. Relevium completes the physician section and, on request, communicates with the airline's medical desk directly — in English.
When a commercial flight is not appropriate
Some patients need a stretcher, continuous monitoring or intensive care in transit. Then the options are a commercial flight with a medical escort and equipment, or an air-ambulance repatriation. Relevium provides the clinical recommendation and the documentation the insurer needs, and coordinates the transport through our provider alliances — staying the single medical point of contact throughout.
