Preparing to fly

Medical conditions


Generally, medical conditions should not inhibit you from flying. However, due to cabin pressure equivalent to an atmospheric pressure at 5,000 to 7,000 feet altitude, special precautions are sometimes required. For more information, please read the details below.


If you have any specific medical questions or concerns, please consult your medical practitioner on your fitness to travel and bring sufficient medication for your trip. Please note that we require medical clearance from our appointed doctor when fitness to travel is in doubt.

You should also ensure that you keep your medication in your hand luggage (not in the checked-in luggage) and have a letter on hand outlining your condition and medication(s), in case you encounter difficulties while overseas.

Asthma and other chest conditions   
Allowed to fly If your asthma condition is under control; it should not prevent you from flying.

Make sure you are well-stocked with your usual inhalers and avoid anything that may trigger an attack.


If you are wheezy before your flight, seek medical advice and treatment.

Special attention required If you experience breathlessness even at rest, cannot manage a 50-meter walk or one flight of stairs without breathing difficulty. If in doubt, get a formal medical evaluation from a medical practitioner who specialises in respiratory conditions.

 Heart conditions  
Allowed to fly As a general guide, people with heart disease who are able to walk up 2 flights of stairs without any problem, or people whose hypertension is well-controlled, should be fit to fly.
Precautions If you recently had a heart attack (myocardial infarction), you are usually advised not to fly.
Special attention required Patients with frequent chest pains (angina attacks) should take extra precaution, as they are twice as likely to suffer an attack in the air as on the ground. They should consult their medical practitioner regarding their fitness to travel, and ensure that they have sufficient medications available to relief chest pains.


Ensure that you have your meals on time and an insulin shot in the middle of the night, if necessary. Special meals may be arranged at time of booking.


People with diabetes are often confused by long-haul travel across time zones, that is, when should they eat and when should they take their diabetic medication or insulin. An advice would be to stay on home time throughout the journey and readjust to local time only upon landing.

 Deep vein thrombosis (DVT)  

DVT is a blood clot that forms in the deep veins within the calf and leg muscles.


It is usually a spontaneous condition that occurs to people, especially those with heart disease, or the elderly. However, periods of prolonged leg immobility can also trigger this occurrence.

Symptoms Warning signs are pain and tenderness in the leg muscles, redness and swelling of the area.

For your safety, if you are prone to DVT, we require that you either sign a Letter of Indemnity or have your medical practitioner provide a medical certificate on your fitness to travel. Please also inform our reservations personnel of your condition when making your reservations.


While flying, we advise that you keep exercising your leg muscles. If possible, take regular walks around the cabin, except when the 'fasten seat belt' sign is displayed. While seated, perform a few simple exercises as shown in the well-being section of this site or refer to the inflight magazine or video.


Avoid alcohol as it increases the risk of developing such a condition. Instead drink more water to keep yourself hydrated as well as to maintain your physical well-being.

Allowed to fly

Recent stroke:
A minimum of a three-week lapse is recommended for anyone intending to fly after a recent stroke. Medical clearance is needed to confirm your fitness to travel.


People with epilepsy are fit to fly but not if the last fit was within the last 24hrs. Medication to control epilepsy should be taken.

Precautions Epilepsy:
People who are prone to regular fits may need to increase their medication onboard on the advice of their medical practitioner, and reduce intake upon arrival at their destination.
Special attention Anaemia:
People with severe anaemia (blood count or haemoglobin less than 8.5 mg/dl) are usually not advised to travel.
