Cabin Crew Medical Exam: Complete Guide to What's Tested
The medical exam is one of the final stages of the cabin crew recruitment process. It is thorough, sometimes nerve-wracking, and covers more than most candidates expect. This guide explains every component of the medical, which conditions can disqualify you, which definitely will not, and exactly how to prepare so there are no surprises on the day.
TLDR
The cabin crew medical exam checks vision, hearing, heart (ECG), blood, urine, dental health, BMI, and general physical fitness. Most candidates pass. Glasses and contacts are fine. LASIK is fine if healed. Small scars are fine. What can disqualify you: color blindness, uncontrolled diabetes, severe asthma, positive drug screening, and active braces at Emirates. Prepare by seeing your GP beforehand, fixing dental issues, achieving a healthy BMI, and stopping any recreational drug use well in advance.
What the medical exam includes
The cabin crew medical is a comprehensive health assessment designed to ensure you can safely perform all duties at altitude. The pressurized cabin environment, physical demands of the job, and responsibility for passenger safety all require crew to meet specific health standards. Here is every component explained in detail.
Vision test
- Distance vision must be correctable to 20/20 (6/6). You do not need perfect natural vision, but your corrected vision with glasses or contacts must meet this standard
- Color vision test using Ishihara plates. You are shown a series of dotted plates with numbers hidden in the pattern. You must identify the numbers correctly. Color blindness is a potential disqualification
- Glasses and contact lenses are fully accepted at most airlines. Bring your current prescription and a spare pair of glasses to the medical
- Recent LASIK or laser eye surgery is accepted if the procedure was at least 6 months prior and your vision has stabilized. Bring documentation from your eye surgeon confirming the procedure date and post-operative results
- Near vision is also tested. You must be able to read standard print at normal reading distance, which is important for reading safety cards, medical labels, and documentation onboard
Hearing test
- Standard audiometry test using headphones in a soundproof booth. Tones are played at different frequencies and volumes. You press a button when you hear each tone
- You must be able to hear normal conversational speech clearly. This is essential for receiving PA announcements, communicating with the flight deck, and hearing passenger requests in a noisy cabin
- Mild hearing loss in specific frequencies may not disqualify you if overall hearing is adequate. The examiner will assess whether your hearing meets the operational requirements for cabin crew duties
- If you use hearing aids, this may be assessed on a case-by-case basis. Full disclosure is important because hearing ability directly relates to safety responsibilities
ECG and heart assessment
- Electrocardiogram (ECG) to check heart rhythm and identify any irregularities. Electrodes are placed on your chest, wrists, and ankles. The test takes about 5 minutes
- Resting heart rate is recorded. Extremely high or low resting heart rates may trigger further investigation. Mild anxiety during the test can raise your heart rate, and examiners account for this
- Blood pressure measurement. Consistently high blood pressure (hypertension) may require further assessment or treatment before clearance is granted
- Any history of heart conditions, murmurs, or surgeries must be disclosed. These do not automatically disqualify you but will require supporting documentation from your cardiologist
Blood tests
- Complete blood count (CBC) to check overall blood health: red cells, white cells, platelets, and hemoglobin levels. Abnormalities may indicate conditions that need further investigation
- Liver function tests to assess liver health. These can be affected by alcohol consumption, medication, and underlying conditions. If you drink regularly, consider reducing intake in the weeks before your medical
- HIV and Hepatitis B/C screening. These are standard for aviation medicals. A positive result does not automatically disqualify you at all airlines, but policies vary. Gulf airlines tend to be stricter
- Blood glucose to screen for diabetes. Uncontrolled diabetes can be disqualifying. If you have managed diabetes, bring documentation showing it is well-controlled with your current treatment plan
- General health markers including cholesterol, kidney function indicators, and thyroid function may be included depending on the airline and medical provider
Urine test
- Drug screening is standard. This tests for recreational drugs including cannabis, cocaine, amphetamines, opiates, and other controlled substances. A positive result is an automatic disqualification at every airline without exception
- Diabetes screening via glucose levels in urine. Elevated glucose can indicate undiagnosed or poorly controlled diabetes
- Kidney function indicators. Protein or other abnormalities in urine can suggest kidney issues that require further investigation
- If you have used recreational drugs, stop immediately and well in advance. Different substances have different detection windows: cannabis can be detected for up to 30 days in regular users, cocaine for 3 to 4 days, and amphetamines for 2 to 4 days. Plan accordingly
Dental assessment
- General dental health is assessed. Healthy teeth and gums are expected. Airlines do not require perfect teeth, but obvious decay, missing front teeth, or significant dental issues may be flagged
- Emirates specifically requires braces to be removed before training begins. If you are currently wearing braces and have an Emirates offer, discuss the timeline with your orthodontist immediately
- Other airlines may be more flexible with braces, particularly if removal is planned within a reasonable timeframe. Clear aligners (Invisalign) are generally more accepted than traditional metal braces
- Consider getting a dental check-up and cleaning before your medical. Fix any obvious cavities or issues. Good dental health contributes to the overall professional appearance airlines expect
BMI and physical assessment
- Height and weight are measured to calculate BMI. The typical acceptable range is 18 to 25, though airlines officially state you must be proportionate to your height rather than citing specific BMI numbers
- The real requirement is that you can move comfortably through the aircraft cabin, fit in jump seats with harnesses, and perform all safety duties without restriction. Extremely high or low BMI may raise concerns about these abilities
- Skin check for visible conditions: scars, eczema, psoriasis, or other skin conditions that may be visible in uniform. Small, concealable scars are generally not an issue. Widespread visible skin conditions may be assessed on a case-by-case basis
- Posture and mobility assessment. You need to demonstrate you can reach overhead bins, bend down to floor level, and move freely without restriction. Any mobility limitations from previous injuries are assessed
- General physical fitness is observed rather than formally tested. You will not be asked to run or do push-ups, but the examiner will note your overall physical condition and any visible health concerns
Conditions that may disqualify you
These conditions can prevent you from passing the medical examination. Some are absolute disqualifications while others depend on severity and management. Understanding them helps you assess your situation honestly before investing time in the application process.
Uncontrolled diabetes
Diabetes that is not well-managed with medication poses a risk in the aviation environment. Blood sugar fluctuations at altitude, irregular meal times, and the physical demands of the job make uncontrolled diabetes a safety concern. Well-controlled diabetes with stable medication may be acceptable at some airlines with supporting medical documentation.
Color blindness
Cabin crew must be able to distinguish colors accurately for safety equipment identification, reading color-coded labels on medical supplies, and identifying emergency lighting. Severe color blindness (particularly red-green deficiency) is typically disqualifying. Mild color vision deficiency may be assessed individually.
Severe asthma requiring daily medication
Asthma that requires daily preventative medication or frequent rescue inhaler use is a concern because cabin air is pressurized and dry, which can exacerbate respiratory conditions. The inability to perform physically demanding safety duties during an asthma episode is the primary concern. Mild, well-controlled asthma with infrequent inhaler use may be acceptable.
Recent major surgery
Major surgery within the previous 6 to 12 months may disqualify you until full recovery is documented. The pressurized cabin environment, physical demands, and lack of immediate medical facilities make it unsafe to operate before complete healing. Bring documentation from your surgeon confirming full recovery and fitness to fly.
Certain mental health conditions requiring specific medications
Some psychiatric medications are not compatible with aviation duties due to side effects like drowsiness, impaired judgment, or slowed reaction times. This does not mean all mental health conditions disqualify you. It depends on the specific condition, the medication, and the airline's aeromedical standards. Full disclosure and supporting documentation are essential.
Active braces (Emirates specifically)
Emirates requires all braces to be removed before the start of training. This is a firm policy that is checked at the medical examination. Other airlines may be more flexible, but Emirates is strict on this point. If you have braces and an Emirates offer, plan for removal with your orthodontist well in advance.
Positive drug screening
Any positive result for recreational drugs is an automatic and immediate disqualification at every airline globally. There are no exceptions, no second chances, and no appeals. This includes cannabis even in jurisdictions where it is legal. Aviation operates under international regulations that prohibit any drug use.
Conditions that usually do NOT disqualify you
Many candidates worry unnecessarily about conditions that are perfectly acceptable. If any of these apply to you, you should still apply with confidence.
The key principle: The medical exam is designed to assess whether you can safely perform cabin crew duties, not to find reasons to reject you. Most candidates pass. The conditions that disqualify are those that would genuinely compromise safety in the aviation environment. If you are generally healthy and your conditions are well-managed, you have a strong chance of passing.

Ask GloHow to prepare for the medical exam
Preparation can make the difference between passing smoothly and encountering avoidable issues. Here is what to do in the weeks and months before your medical.
- 1
Get a pre-check with your GP
Visit your doctor for a general health check 2 to 3 months before your airline medical. Ask them to check your blood pressure, blood glucose, and vision. This gives you time to address any issues that arise. If your blood pressure is slightly high, your GP can help you bring it down before the airline medical.
- 2
Fix dental issues beforehand
Get a dental check-up and professional cleaning. Fill any cavities. If you have braces and are applying to Emirates, discuss your removal timeline with your orthodontist immediately. Dental work takes time, so start early. Arriving at the medical with obvious dental problems creates an unnecessary risk.
- 3
Achieve and maintain a healthy BMI
If you are concerned about your weight, start working on it as soon as you decide to apply. Gradual, sustainable changes are better than crash diets. Aim for a BMI in the 18 to 25 range. Focus on overall fitness and proportion. The examiner is looking at your ability to perform duties, not judging your body. But being within a healthy range removes any potential concern.
- 4
Stop recreational drug use immediately
If you use any recreational drugs, stop now. Not in a month. Not next week. Now. Drug screening is part of every airline medical and a positive result is an instant, irreversible disqualification. Cannabis stays in your system for up to 30 days for regular users. Other substances have shorter but still significant detection windows. There are zero exceptions to this rule.
- 5
Bring all medical records and prescriptions
Gather documentation for any pre-existing conditions, medications, surgeries, and treatments. If you had LASIK, bring your surgeon's clearance letter. If you take medication for any condition, bring the prescription details. If you have been treated for any significant health issue, bring a letter from your doctor confirming your current status. Having documentation ready shows professionalism and prevents delays.
- 6
Reduce alcohol intake in the weeks before
Alcohol affects liver function test results. Heavy or regular drinking in the weeks before your medical can result in elevated liver enzymes, which may require retesting or further investigation. Consider reducing or stopping alcohol consumption 2 to 4 weeks before your medical to ensure clean results.
- 7
Get a good night of sleep before the medical
Arrive well-rested. Sleep affects blood pressure, heart rate, and your overall presentation. Being visibly exhausted raises questions. Rest the night before and eat a light meal in the morning (unless you have been instructed to fast for blood tests, in which case eat after the blood draw).
- 8
Stay hydrated
Drink plenty of water in the days before your medical. Dehydration affects blood test results and can make drawing blood difficult. It can also temporarily raise blood pressure. Being well-hydrated makes every component of the medical smoother.
Medical exam by airline
Each airline conducts their medical through specific providers and locations. Knowing where you will go helps with planning and reduces anxiety on the day.
Emirates
Emirates Group Headquarters and Dnata Health Services, Dubai
The Emirates medical is conducted at their own facilities in Dubai. It is one of the most thorough medical examinations in the industry. Expect the full day to be dedicated to the medical. Bring all prescriptions, medical records, and documentation for any pre-existing conditions.
Qatar Airways
Hamad Medical Corporation, Doha
Qatar Airways uses Hamad Medical Corporation for their cabin crew medicals. The examination is comprehensive and includes the tattoo check (zero tolerance policy). Allow a full day. Qatar's medical is known for being particularly thorough.
Etihad Airways
Designated medical facilities, Abu Dhabi
Etihad conducts medicals through designated aviation medical examiners in Abu Dhabi. The process is similar to Emirates in scope. Documentation of any pre-existing conditions should be brought in English.
British Airways
Heathrow Medical Centre and designated AMEs
BA medicals are conducted through approved Aviation Medical Examiners (AMEs) near Heathrow. The examination follows UK Civil Aviation Authority standards. You may be able to complete the medical closer to your home through a designated AME.
Singapore Airlines
SIA designated medical facilities, Singapore
Singapore Airlines conducts medicals through their designated facilities in Singapore. The standard follows Singapore Civil Aviation Authority requirements. The examination is thorough but efficient.
Frequently asked questions
Will I fail the medical if I wear glasses?
No. Wearing glasses or contact lenses is completely acceptable at virtually every airline. The requirement is that your corrected vision (with glasses or contacts on) reaches 20/20 or 6/6. You do not need perfect natural vision. Bring your current prescription to the medical and carry a spare pair of glasses. Many successful cabin crew members wear contact lenses while operating.
How strict is the BMI requirement?
Airlines do not typically publish a specific BMI cutoff number. The official requirement is usually stated as being proportionate to height or having a weight that allows you to perform all cabin crew duties effectively. In practice, the acceptable range aligns roughly with a BMI of 18 to 25, but this is not a hard rule. The real test is whether you can fit comfortably in the jump seat harness, move through the cabin without restriction, and perform safety duties. If you are concerned, focus on overall fitness and proportion rather than a specific number.
Can I be cabin crew with asthma?
It depends on the severity. Mild asthma that is well-controlled and requires only occasional use of a rescue inhaler is generally acceptable at most airlines. Moderate to severe asthma requiring daily preventative medication, frequent rescue inhaler use, or a history of hospitalization for asthma attacks is more likely to be disqualifying. The cabin environment (pressurized, low humidity air) can aggravate asthma, and you must be able to perform physically demanding safety duties at all times.
What happens if I fail the medical exam?
If you fail the medical, the outcome depends on the reason. Some conditions can be addressed and you can retake the medical after treatment. For example, if your blood pressure was high, you may be asked to see your GP, start treatment, and return for a recheck. If the condition is permanently disqualifying (such as color blindness), you will not be able to proceed with that airline. Some airlines allow you to reapply after addressing medical concerns, while others require a waiting period.
Do I need to disclose my medical history?
Yes, fully and honestly. The medical questionnaire will ask about your complete medical history including surgeries, hospitalizations, ongoing conditions, medications, and mental health history. Lying or omitting information is grounds for immediate termination if discovered later, even years into your career. Aviation medical standards exist for safety. If something in your history raises a flag, it is better to address it honestly and provide supporting documentation than to be caught concealing it.
Is the medical exam the same at every airline?
The core components are similar because they are based on international aviation medical standards. However, the thoroughness and specific requirements vary. Gulf airlines (Emirates, Qatar, Etihad) tend to be more comprehensive, including dental checks and tattoo inspections. European and US airlines follow their regional aviation authority requirements which may differ in specific areas. The medical for a Class 2 aviation medical certificate is the baseline that all airlines use.
Can I take my regular medication before the medical?
Continue taking any prescribed medication as normal unless specifically instructed otherwise. Stopping medication before a medical to try to appear healthier is dangerous and counterproductive. If you take medication for blood pressure, diabetes, thyroid, or any other condition, bring the medications with you and declare them on the medical form. The examiner needs to see that your condition is well-managed with your current treatment.
How long does the medical exam take?
Plan for a full day. The actual examinations typically take 3 to 5 hours depending on the airline and medical provider. This includes waiting time between different tests, paperwork, and any additional assessments. Emirates medicals can take most of the day. Some airlines split the medical across two appointments. Bring water, snacks (you may need to fast for blood tests beforehand, so eat after that component), and something to read during waiting periods.
