MEDIF stands for Medical Information Form. It is a form used by many airlines to obtain medical information about a passenger when the airline needs to assess whether they are fit to fly or what medical assistance, equipment or arrangements may be required for the journey.
You might be asked for a MEDIF if you have a recent illness or operation, need oxygen during the flight, require certain medical equipment, need a stretcher or have another medical situation that the airline wants its medical team to review.

Not every disabled passenger needs a MEDIF. Disability assistance and medical clearance are different processes, although they can overlap.
What Does MEDIF Stand For?
MEDIF means Medical Information Form. Airlines use MEDIF documentation to collect relevant medical information before a passenger flies.
The form can help an airline decide whether a passenger is medically fit to travel on a commercial aircraft and whether special medical arrangements are necessary.
There is not one universal passenger form used identically by every airline. Airlines can have their own MEDIF documents, medical-clearance procedures, submission deadlines and approval processes.
Why Do Airlines Use MEDIF Forms?
An aircraft cabin is a different environment from being on the ground. Cabin pressure, lower available oxygen, limited space and restricted access to medical care can affect some passengers with medical conditions.
An airline may therefore need medical information before accepting a passenger for travel or confirming a particular medical service.
The MEDIF process can help the airline understand:
- the passenger’s current medical condition;
- whether the condition is stable;
- whether the passenger is considered fit to fly;
- whether oxygen or other medical support is needed;
- whether medical equipment will be used on board;
- whether a medical escort or companion is required;
- whether a stretcher or special seating arrangement is needed; and
- whether the proposed journey creates a medical concern that needs further assessment.
Who Might Need a MEDIF?
The circumstances vary between airlines. A MEDIF may be requested when a passenger’s health, treatment or required medical service needs assessment before flying.
Examples can include passengers who:
- need supplemental oxygen during the flight;
- have recently had surgery or a significant medical procedure;
- have recently been seriously ill or admitted to hospital;
- need to travel on a stretcher;
- require certain medical equipment during the flight;
- have a condition that could deteriorate in the aircraft environment;
- need medical care or monitoring during the journey; or
- have been specifically referred for medical clearance by the airline.
This is not a complete list. The operating airline decides when its medical-clearance process is required.
Helpful guides to airline codes related to using the MEDIF form:
- Travelling as a medical passanger using the MEDA code
- Using a stretcher when travelling – the STCR airline code
- Travelling with oxygen – the OXYG code and PPOC code
Does Every Disabled Passenger Need a MEDIF?
No. Having a disability does not automatically mean you need medical clearance to fly.
Many disabled passengers travel using ordinary airport and airline special assistance without completing a MEDIF. For example, a passenger who needs wheelchair assistance because they cannot walk long airport distances may need an assistance request but no medical assessment.
Similarly, an autistic passenger may need disability-related assistance without having a medical reason for the airline to assess whether they are fit to fly.
If you only need airport support, my guide to getting help at the airport as a disabled traveller explains the special assistance process.
MEDIF vs Special Assistance: What Is the Difference?
Special assistance is practical disability or reduced-mobility support for the journey. MEDIF is a medical-information and clearance process.
| MEDIF | Special Assistance |
|---|---|
| Medical information and assessment | Practical support during travel |
| May require information from a doctor | Usually requested from the airline or assistance service |
| Used when medical fitness or arrangements need review | Used for disability and reduced-mobility assistance |
| Not required for every disabled passenger | Can be used without needing medical clearance |
A passenger can need both. For example, someone may require wheelchair assistance through the airport and also need a MEDIF because they require oxygen on board.
MEDIF vs MEDA: What Is the Difference?
MEDIF and MEDA are related airline terms but they are not interchangeable.
MEDIF refers to the Medical Information Form or medical-information process used to assess a passenger.
MEDA is an airline Special Service Request code associated with a medical case that has been authorised for travel following medical clearance.
You may therefore encounter MEDIF while submitting information for assessment and MEDA within airline reservation systems after the medical case has been handled.
Who Completes a MEDIF Form?
A MEDIF commonly contains sections for the passenger and sections that need to be completed by a treating doctor or other appropriate medical professional.
The exact format varies by airline. The medical section may ask for information about diagnosis, current condition, treatment, mobility, oxygen requirements and whether the passenger is considered fit to fly.
Read the airline’s instructions before arranging an appointment to do the MEDIF form with your doctor. This helps ensure the correct person completes the form and that it is completed within any validity period set by the airline.
What Information Is Usually on a MEDIF?
Airline forms differ, but information requested may include:
- passenger and booking details;
- medical diagnosis or reason for clearance;
- current symptoms and stability;
- recent operations or hospital treatment;
- medication and treatment information;
- mobility and ability to care for yourself during the flight;
- oxygen requirements;
- medical equipment needed on board;
- whether a medical escort is necessary;
- infectious-disease considerations where relevant; and
- the treating clinician’s assessment of fitness to fly.
Only provide the information requested through the airline’s approved medical process. If you are unsure why information is required, ask the airline’s medical or accessibility team.
Is MEDIF the Same as a Fit-to-Fly Letter?
Not necessarily.
A fit-to-fly letter is usually a statement from a healthcare professional about a passenger’s medical suitability for air travel. A MEDIF is an airline’s structured medical-information form and can ask for considerably more detail.
If an airline specifically asks for its MEDIF, do not assume a general doctor’s letter will be accepted instead. Use the documentation the airline requests.
How Do You Get a MEDIF Form?
Start with the operating airline’s official website or contact its medical assistance, accessibility or special assistance team.
Many airlines provide a downloadable MEDIF or an online medical-clearance process. Others send the required documentation after you explain your circumstances.
Use the form supplied by the airline you are actually flying with. Do not download a random MEDIF from another carrier and assume it will be accepted.
When Should You Submit a MEDIF?
Submission deadlines vary by airline and by the type of medical request.
Some medical services need substantial advance notice because the airline must review the case and arrange equipment or operational support. At the same time, a medical form may need to be recent enough to accurately describe your condition.
Check the airline’s instructions as soon as you know you may require medical clearance. Do not rely on a universal deadline.
What Happens After You Submit a MEDIF?
The airline or its medical service reviews the information and decides what happens next.
Possible outcomes include:
- medical clearance for the booked journey;
- a request for additional medical information;
- approval subject to particular arrangements;
- confirmation of oxygen, stretcher or medical-equipment requirements;
- a requirement for an escort or companion in specific circumstances; or
- advice that travel should be postponed or cannot be accepted in the proposed circumstances.
Do not assume that submitting the form means clearance has been granted. Wait for confirmation from the airline.
Do You Need a New MEDIF for Every Flight?
Possibly. MEDIF approval can be specific to an airline, itinerary, date range or medical situation.
If you have connecting flights operated by different airlines, one carrier’s medical clearance may not automatically satisfy another carrier.
Ask each operating airline whether separate documentation is required. This is especially important on codeshare itineraries, where the airline selling the ticket may not operate every flight.
MEDIF and In-Flight Oxygen
Passengers who need supplemental oxygen during a flight are among those who may be asked to complete medical-clearance documentation.
The airline may need information about the prescribed flow rate, when oxygen is required and whether an approved portable oxygen concentrator will be used.
Airlines use SSR codes to communicate these arrangements within reservations and the two you might see for a passenger who needs oxygen are OXYG and PPOC. You can see other medical and disability codes in our guide to airline and airport disability codes.
MEDIF and Medical Equipment
Some medical devices can be carried without a full MEDIF process, while others require advance approval or additional information. The requirements depend on the equipment and airline.
If equipment will be used during the flight, the airline may need technical details such as its make and model, dimensions, power source and battery specifications.
Medical equipment can also affect your baggage planning, you can learn more about this in our guide to medical luggage. Our medical luggage guide for major airlines provides a starting point for checking airline policies, but confirm the current rules directly with your carrier.
MEDIF and Wheelchair Assistance
Needing a wheelchair at the airport does not automatically mean you need a MEDIF.
Airlines use specific SSR codes such as WCHR, WCHS and WCHC to describe different levels of wheelchair assistance. These are separate from medical clearance.
If there is an additional medical issue that the airline needs to assess, you could have wheelchair assistance recorded and also be asked to complete a MEDIF.
Do Autistic Passengers Need a MEDIF?
Autism by itself does not mean a passenger automatically needs a MEDIF.
An autistic traveller may need disability assistance because of sensory, communication, processing or other support needs without requiring medical clearance to fly.
If there is a separate medical issue, the airline may ask for medical information relating to that situation. Explain the practical assistance needed and let the airline distinguish between its accessibility and medical-clearance processes.
Can an Airline Refuse Medical Clearance?
An airline can decide that it cannot safely accommodate a particular medical situation on a specific flight, or that further information or arrangements are needed before travel.
Commercial aircraft are not hospitals, and the medical resources available on board are limited. Operational factors can also affect what an airline can provide.
If clearance is not granted, ask the airline what information or change in circumstances would be needed for the journey to be reconsidered. Discuss any medical implications with your treating healthcare professional.
What to Do Before Travelling With a MEDIF
- Contact the operating airline as early as possible.
- Use the airline’s current MEDIF form or medical-clearance system.
- Check which sections must be completed by a healthcare professional.
- Follow the airline’s submission and validity deadlines.
- Provide accurate information about medical equipment and oxygen requirements.
- Wait for written confirmation of medical clearance.
- Confirm any separate airport special assistance you need.
- Keep relevant medical and airline documentation accessible during the journey.
- Recheck arrangements if your medical condition changes before departure.
If your condition changes significantly after the airline has approved travel, contact the airline rather than assuming the original clearance remains valid.
Frequently Asked Questions About MEDIF
What does MEDIF mean?
MEDIF stands for Medical Information Form. Airlines use it to obtain medical information when a passenger’s fitness to fly or medical arrangements need assessment.
Is a MEDIF a fit-to-fly certificate?
Not exactly. A MEDIF is an airline medical-information form, while a fit-to-fly certificate or letter is usually produced by a healthcare professional. If the airline asks for its MEDIF, use the form it specifies.
Does a doctor have to complete MEDIF?
MEDIF forms commonly include a section that must be completed by a treating doctor or other appropriate healthcare professional. Follow the instructions on your airline’s form.
Do wheelchair users need MEDIF?
Not simply because they use a wheelchair. Wheelchair assistance and medical clearance are separate. A MEDIF may only be needed if there is an additional medical reason for assessment.
Do autistic passengers need MEDIF?
Not automatically. An autistic passenger can request disability-related assistance without requiring medical clearance. A MEDIF may be relevant if there is a separate medical issue the airline needs to assess.
How long does MEDIF approval last?
There is no universal validity period. Approval can depend on the airline, itinerary, dates and passenger’s medical circumstances. Check the confirmation provided by your airline.
The simplest way to understand the MEDIF form is that it gives an airline the medical information it needs to assess a passenger or arrange medical support before flying. It is not a general requirement for every disabled traveller.
If an airline asks you to complete a MEDIF form, use that airline’s current form, follow its deadlines and wait for confirmation that medical clearance has been granted. Arrange any separate airport assistance at the same time so both the medical and practical parts of your journey are covered.
