To ease motion sickness during your flight, look straight ahead and keep your eyes focused on a non-moving object.
Air pressure in the cabin falls as the aircraft gains height. This can cause the amount of oxygen in your blood to drop. The aircraft cabin is pressurised to keep this fall to a minimum. However, you may experience ear discomfort during take off and landing. Chewing, swallowing, or yawning can relieve these symptoms.
Existing medical conditions
If you can walk for 50 metres without getting breathless, you should be able to fly without difficulty—even if you have an existing medical condition. However, check with your doctor if you have a respiratory or heart problem.
Asthma sufferers should bring their inhalers onboard with them.
Do not fly within seven days of a heart attack unless cleared by your doctor. To avoid complications, it is normally best to delay your flight for about a month.
If you are going to cross several time zones, please consult your doctor about managing your insulin dosage before you fly.
You can travel by air up to 28 weeks into a normal pregnancy. With a medical certificate, you can fly during later stages of pregnancy—up to 35 weeks for a single child and 32 weeks for twins.
