Certain medical conditions can be affected by flying, and may require medical clearance, which is written confirmation from your doctor that you are well enough to fly. These conditions include:
- Heart or blood vessel problems such as a heart attack, heart failure, angina or stroke.
- Deep Vein Thrombosis
- Breathing difficulties such as chronic bronchitis or emphysema, pneumothorax (a collapsed lung), pulmonary embolism (a blood clot on the lung), or asthma, especially if you may need additional oxygen or use of a nebuliser during your flight
- A recent head injury
- Stomach or bowel problems
- A current infectious disease
- Ear or sinus pain
- Limb injuries, including fractures
- Psychiatric problems
- Any recent surgery
For passengers suffering from conditions like heart or lung disease, or blood disorders such as anaemia (including sickle cell anaemia), the lower oxygen levels in the cabin could lead to oxygen deprivation (hypoxia), making additional oxygen supplies necessary.
Additionally, the lower air pressure means that air within the cabin is expanded by about 30%. This could cause problems for passengers who have recently undergone surgery, have abdominal health problems, or blocked ears or sinuses.
If you are affected by any of these conditions, you should check your doctor is happy for you to fly. You should also check with our Special Assistance team in case you require official medical clearance from your doctor before you can fly.
