Thanks to telemedicine, you can now obtain this certificate through a quick online video consultation β no clinic visit needed.

πΉ What Is a Fit-to-Fly Certificate?
A fit-to-fly certificate (sometimes called a medical clearance to fly) is an official document issued by a licensed doctor confirming that your current health condition allows you to travel safely by air. It typically includes:
- Your full name and date of birth
- Date of the medical assessment
- A statement confirming your fitness to fly
- Any conditions or restrictions (e.g., supplemental oxygen required)
- The doctor's name, medical registration number and signature
- The validity period of the certificate
Airlines may request this document at check-in, boarding, or when booking assistance services.
πΉ When Do Airlines Require a Fit-to-Fly Certificate?
According to IATA guidelines and individual airline policies, you may need medical clearance to fly if:
- You've recently been ill β particularly with respiratory infections, infectious diseases or conditions that could worsen at altitude
- You've had surgery or a medical procedure β airlines typically require clearance if surgery was within the last 7β14 days, depending on the procedure
- You're pregnant β most airlines allow flying up to 36 weeks for single pregnancies and 32 weeks for multiple pregnancies, but many require a certificate from 28 weeks onwards
- You have a chronic condition β such as severe asthma, heart disease or a recent stroke
- You require supplemental oxygen or special assistance during the flight
- You've recently been hospitalised β particularly for cardiac events, blood clots or pneumothorax

πΉ What Does the Doctor Assess?
During a fit-to-fly assessment, the doctor will review:
- Your current symptoms β fever, cough, breathing difficulties, pain levels
- Recent medical history β any illness, surgery, hospitalisation or medical event in the past 2β4 weeks
- Chronic conditions β whether your ongoing conditions are stable and safe for air travel
- Medication β whether your current medications are compatible with flying (some may be affected by cabin pressure or dehydration)
- Risk of in-flight complications β including deep vein thrombosis (DVT), altitude-related issues, and the risk of deterioration during a long flight
- Pregnancy stage β gestational age and any complications
The doctor will then decide whether it is safe for you to fly and, if so, issue the certificate with any relevant conditions or recommendations.
πΉ How to Get a Fit-to-Fly Certificate Online
The process with UrgentDoc is straightforward:
- Book your consultation online β choose a time that works for you, including evenings and weekends
- Speak with a licensed doctor β a short video consultation (typically 10β20 minutes) where the doctor reviews your health and travel plans
- Receive your digital certificate β if you're fit to fly, the certificate is issued and sent to your email, usually within hours
- Present to your airline β the certificate includes the doctor's full credentials, registration number and digital signature
The entire process usually takes under 30 minutes from booking to certificate.
πΉ Who Does NOT Need a Fit-to-Fly Certificate?
Not every health condition requires airline clearance. You generally do not need a fit-to-fly certificate if:
- You have a common cold or mild respiratory symptoms without fever
- You are taking stable, long-term medication for a well-controlled chronic condition
- You have a minor injury (e.g., a sprain) that doesn't require mobility assistance
- You are pregnant but under 28 weeks with no complications
- You've had minor dental work or outpatient procedures more than 48 hours ago
If you're unsure whether your situation requires a certificate, it's always worth checking with your airline or asking during an online consultation.
πΉ Flying with Specific Medical Conditions
Different conditions carry different risks at altitude. Cabin pressure at cruising altitude is equivalent to being at approximately 1,800β2,400 metres, which reduces the amount of oxygen available. This can affect certain conditions:
Respiratory conditions
Passengers with severe asthma, COPD or recent pneumonia may need supplemental oxygen. Airlines typically require at least 48β72 hours' notice for onboard oxygen. A fit-to-fly assessment can determine whether you need this.
Cardiovascular conditions
According to the British Heart Foundation, most people with stable heart conditions can fly safely. However, flying within 2 weeks of a heart attack or within 2β6 weeks of cardiac surgery usually requires medical clearance.
Deep vein thrombosis (DVT) risk
Long-haul flights increase DVT risk due to prolonged immobility. The NHS recommends moving around the cabin, staying hydrated and wearing compression stockings if at higher risk. A fit-to-fly assessment can advise on personal DVT prevention strategies.
Mental health conditions
Severe anxiety, recent psychiatric episodes or conditions requiring sedation may warrant medical clearance. Your doctor can advise on managing anxiety during flights and whether any medication adjustments are needed.
πΉ Are Online Fit-to-Fly Certificates Accepted by Airlines?
Yes. Online fit-to-fly certificates are accepted by major airlines provided they:
- Are issued by a licensed, registered medical doctor
- Include the doctor's name, medical registration number and signature
- State clearly that you are medically fit to travel by air
- Include the date of assessment and validity period
- Are presented in English (UrgentDoc certificates are issued in English by default)
UrgentDoc certificates meet all of these criteria. Our doctors are EU-licensed and registered with Spanish medical authorities.

πΉ How Much Does a Fit-to-Fly Certificate Cost?
Costs vary depending on the provider:
- NHS (UK): GPs may charge Β£25βΒ£50 as it's a private service not covered by the NHS
- Private clinics in Spain: Typically β¬50ββ¬100 for an in-person visit
- UrgentDoc (online): Consultations from β¬20, with the certificate included if clinically appropriate
Online consultations often represent the fastest and most cost-effective option, especially if you're already abroad and don't have a local GP.
πΉ What If You're Not Fit to Fly?
If the doctor determines that flying poses a health risk, they will:
- Explain why it is not safe for you to travel at this time
- Advise on when you might be safe to fly (e.g., after a recovery period)
- If relevant, issue a letter confirming your medical inability to fly β this can support travel insurance claims or airline rebooking requests

β Frequently Asked Questions
How quickly can I get a fit-to-fly certificate?
With UrgentDoc, you can typically receive your certificate within a few hours of booking. Same-day appointments are available, including evenings and weekends.
Do I need a fit-to-fly certificate after COVID-19?
Most airlines no longer require COVID-specific certificates, but if you had severe symptoms or were recently hospitalised, a general fit-to-fly certificate may be prudent. Check your airline's current policy.
Is a fit-to-fly certificate the same as a MEDIF form?
Not exactly. A MEDIF (Medical Information Form) is an airline-specific form that must be completed by your doctor and submitted to the airline's medical team in advance. A fit-to-fly certificate is a general medical letter. Some situations require a MEDIF rather than a standard certificate β check with your airline.
Can I get a fit-to-fly certificate while abroad?
Yes. UrgentDoc offers online consultations from anywhere in Spain. You don't need a local GP or health card β just a valid ID and an internet connection.
What if my airline doesn't accept the certificate?
Contact your airline in advance to confirm their requirements. UrgentDoc certificates include all standard elements (doctor credentials, registration number, assessment date, clear fitness statement) and are accepted by the vast majority of carriers.
Do children need a fit-to-fly certificate?
Children may need a certificate if they have been recently ill, hospitalised or had surgery. The same principles apply as for adults β check your airline's policy.
