Fit to Fly Certificate: Medical Clearance for Air Travel
A fit to fly certificate confirms you're medically cleared for air travel, commonly needed after surgery, during pregnancy, or with certain medical conditions. Airlines set their own specific requirements, so it's worth checking with your airline before booking your consult.

Flying With Confidence
Fit-to-fly requests sit within OMC Health's fitness for work certificate pathway, but the airline's current medical-clearance requirements determine what evidence or form is needed. An AHPRA-registered GP can assess what can be clinically supported from the consultation and available information.
Airlines set their own medical clearance policies instead of following one shared passenger-documentation standard, so the exact fit-to-fly requirements depend on your airline, route and why clearance is needed.
This page explains when airlines may request medical clearance, how airline-specific forms work, what the GP assesses and what to check before booking.

What Is a Fit to Fly Certificate?
A fit-to-fly letter records that a registered medical practitioner has assessed the relevant circumstances and considers air travel medically reasonable for the stated period, where that conclusion can be clinically supported.
The letter does not override the airline's own medical-clearance process or guarantee that the carrier will approve travel.
Check Whether the Airline Needs Its Own Medical Form
A fit-to-fly letter is not interchangeable with every airline's medical-clearance process. Some carriers accept a clinician letter for a straightforward temporary condition, while others use a MEDIF or other airline-specific form, especially where in-flight assistance, oxygen, recent surgery or a significant medical condition is involved.
Check the airline's current medical page before booking and upload any required form. For example, Qantas publishes a Travel Clearance Form and medical-clearance criteria, while Virgin Australia publishes its own Medical Clearance Guidelines and Form.

When Airlines Require a Fit to Fly Certificate
Medical clearance may be required after recent surgery, during later pregnancy or where a medical condition, oxygen requirement or need for in-flight assistance falls within the carrier's clearance criteria.
The airline determines whether its medical-clearance process applies, so check the current carrier policy before assuming a general GP letter is sufficient.
OMC Health consultations are conducted by AHPRA-registered GPs. Practitioner registration can be checked on the AHPRA public register.
Late Pregnancy Travel and Gestation Thresholds
Airline documentation and travel limits vary by carrier, route, gestation and whether the pregnancy is single or multiple. Check the airline's current medical policy before booking. RANZCOG provides general pregnancy travel guidance, but the carrier's current rules control its boarding and documentation requirements.
If the airline provides a pregnancy certificate template or asks for specific details such as estimated delivery date, pregnancy type or complications, have those requirements available for the consultation.
See how long a telehealth consultation usually takesPost-Surgery Fit to Fly Assessment
There is no single waiting period that applies to every operation or airline. The procedure, current recovery, complications, mobility, clot risk and the carrier's own clearance rules may all be relevant.
Bring recent discharge information, specialist restrictions and the airline's form where available. If the assessment depends on examination or recent investigations that cannot be adequately reviewed by telehealth, further assessment may be required.
Situations Where a GP Will Not Provide Clearance
A telehealth GP should not be positioned as a substitute for specialist or airline medical review where the condition requires examination, recent investigation results or complex fitness-to-fly assessment. Examples can include oxygen requirements, unstable cardiac or respiratory disease, recent major surgery, or another situation where the airline or treating specialist requires more detailed clearance.
The Medical Board of Australia's Good medical practice code requires clinical decisions to be based on appropriate assessment and professional judgement. Healthdirect's travel health guidance also advises medical review before travel for people at increased clot risk, including after recent surgery, during pregnancy or with relevant medical conditions.
How the GP Assesses Fitness for Air Travel
The GP reviews the reason clearance is requested, current symptoms, relevant history, recovery stage or pregnancy circumstances, available records, travel dates and the airline's stated requirements.
A letter or airline form is completed only where the requested statement can be clinically supported. The airline remains responsible for deciding whether its own travel-clearance requirements have been met.
What 'Medically Cleared to Fly' Means Clinically
It means the GP can support the requested travel-fitness statement based on the condition, available clinical information and circumstances assessed at that time.
It is not a guarantee against an in-flight medical event and does not replace the airline's final decision where the carrier requires its own medical review.
If illness prevents travel, see medical evidence for a travel insurance claimHow Far in Advance Should You Book?
Start by checking the airline's submission deadline and how recently it requires the medical assessment, letter or form to be dated. Different carriers and medical circumstances can use different timeframes.
For changing circumstances such as post-operative recovery or pregnancy, the GP also needs sufficiently current information to support the requested statement.

International Travel and Destination-Specific Requirements
Airline medical clearance and destination health or entry requirements are separate issues. International travel can involve additional vaccination, infectious-disease, medication or documentation requirements that are not answered by a fit-to-fly letter.
Check the carrier, destination requirements and any transit-country rules that apply to your itinerary before relying on one document for the whole journey.
What If the Airline Doesn't Accept Your Letter?
Check the reason with the airline's medical or accessibility team. The carrier may require its own form, more recent information, specialist evidence or additional details about assistance, oxygen, equipment or the medical condition.
Clarify the missing requirement before arranging another consultation so the GP can determine whether the requested information can be appropriately provided.
Fit to Fly for Chronic Conditions
A stable chronic condition does not automatically require or exclude medical clearance. The carrier's policy, current stability, recent changes, treatment requirements and need for equipment or assistance determine what information may be needed.
If a specialist manages the condition or the airline requests specialist evidence, bring the relevant recent information to the assessment.
Do You Need a New Letter for Every Trip?
That depends on the airline's policy and whether the relevant medical circumstances have changed. Some clearance processes apply to specific flights or date ranges, while some carriers have separate processes for stable long-term conditions.
Check the carrier before reusing an earlier letter, particularly where the original document related to pregnancy, recent surgery or another changing condition.
Fit to Fly Letters for Connecting or Long-Haul Flights
The full itinerary can matter where prolonged immobility, multiple sectors, different operating carriers or reduced access to medical assistance affect the clearance question.
Provide the GP with the relevant flight duration, connections and return travel details, particularly when the airline form asks for specific flights or dates.
What to Do If You're Told You're Not Fit to Fly
A decision not to provide clearance should be treated as a clinical safety outcome rather than an administrative obstacle.
Discuss what further assessment, recovery period or specialist information may be needed and contact the airline or booking provider about changing the journey where appropriate.
Fit to Fly Letters for Children and Infants
Airline requirements for infants and children can differ according to age, health condition, recent treatment and the carrier's own medical-clearance rules.
Check the airline before booking the consultation and provide any medical form or written requirement it has issued.
Before the consultation
Have the child's travel dates, relevant medical information and airline requirements ready, and confirm whether the child needs to participate in the real-time assessment.
Keeping a Copy of Your Fit to Fly Letter
Keep the completed letter or airline medical form accessible in the format required by the carrier.
If the airline has approved a medical-clearance request separately, also retain any confirmation or reference supplied by its medical team.
Keep it accessible
- Save the issued document securely on your phone
- Carry a printed copy if the airline requests one
- Keep airline approval or medical-team correspondence available
Certificate Verification
Once an OMC Health certificate or letter is issued, its authenticity can be checked through OMC Health's verification service.
Frequently asked questions
View all FAQsThis varies by airline, with most requiring a letter from around 28 weeks and some restricting travel entirely after 36 weeks for a single pregnancy. Always check your specific airline's current policy before booking.
This depends heavily on the specific procedure, with some surgeries requiring just a few days of recovery and others needing several weeks before flying is considered safe. The GP assesses your individual recovery rather than applying a fixed rule.
No. Each airline sets its own medical clearance policy, so requirements for pregnancy, recent surgery, or certain conditions can vary between carriers, even for the same underlying situation.
Airlines can refuse boarding if a required medical clearance isn't provided, so it's worth confirming your specific airline's requirements and booking your consult well before your travel date.
