Tips for a Comfortable Flight
For a healthy and comfortable time on board, please note the following characteristics of the inflight environment and their possible health effects on health:

1. The Inflight Environment
Tips for a Comfortable Flight

Atmospheric pressure
During flights, cabin pressure is adjusted by air-conditioning but remains about 0.2-0.3 hPa lower than at sea level about equal to being on a mountain 2,000-2,500 meters high. It is said that the large pressure change that occurs 15-30 minutes after takeoff, and again before landing, may cause ear problems for some passengers who are not in good physical condition.

Temperature and humidity
Cabin temperature is set to 22-26 C. During long flights, cabin humidity tends to drop below 20% as the humidity of the air brought in from the outside is extremely low. Due to the dryness in the cabin, the body may dehydrate, causing nasal or throat pain as well as discomfort to contact lenses wearers.

Oxygen dilution
Along with the decrease in atmospheric pressure, the concentration of oxygen in the cabin decreases 20-30% (compared to sea level). While this is not a problem for most passengers, those suffering from respiratory diseases, cerebro-vascular disorders or serious anemia may be affected under certain, rare circumstances.

Airliners produce minimal vibration, but passengers who tend to feel nauseous in motor vehicles may suffer ill effects if the flight encounters turbulence. Because not all turbulence is foreseeable, we recommend that you keep your seatbelt fastened whenever you are in your seat.

When you remain seated in the same position for a prolonged period, veins in the feet and legs can become constricted. This in turn can lead to the formation of blood clots in the leg, also known as deep vein thrombosis (DVT).

DVT is not necessarily accompanied by any overt signs, and an expert opinion is needed to confirm the condition, but the following symptoms may occur: pain, swelling and discoloration of the leg, congestion of the superficial veins of the leg, or the leg feeling warm to the touch.

If a clot does build up, there is a risk that it may detach itself and travel to other parts of the body, such as the lung, where it can cause chest pain, shortness of breath and even sudden death. This may occur hours or even days after the clot's formation.

DVT is not related to class of air travel. It has wrongly been called 'Economy Class Syndrome', whereas in fact it can affect passengers in any cabin. Nor is it limited to air travel, as people sitting immobile in cars, trains or buses may also be at risk.

Some passengers are more prone to DVT than others, and if you have any health concerns, or if any of the following apply to you, you are advised to seek medical advice before flying:

personal or family history of DVT and/or pulmonary embolism
recent major surgery
malignancy, previous or current
(known) thrombophilia
varicose veins
heart failure or recent myocardial infarction
hormone therapy, including the oral contraceptive pill
polycythemia, thrombocytosis
pregnancy or recent postpartum condition
recent injury, including limb fracture
recent immobilization for a day or more

To reduce the risk of DVT, we recommend that all passengers follow the steps outlined in this leaflet, paying particular attention to the sections on exercise and drinking adequate fluids/ water.

2. In the Cabin
Wear loose fitting comfortable clothes. To maintain your body temperature, it is a good idea to bring a jacket or other warm items of clothing.

Drink adequate fluids, especially water. If you choose to drink beverages containing alcohol and/or caffeine or soda beverages please do so in moderation.


During long flights, move your feet and legs every 2-3 hours, and avoid crossing your legs when seated. We present an inflight video of stretch exercises that can be performed while seated, and which are believed by experts to be effective in minimizing the risk of developing DVT.

# Clothing, beverage and exercise are considered to be effective in preventing DVT.
- Stretch your feet forward as far as possible, then back.
- Stretch your feet forward as far as possible, then back.
- Turn your feet in the same direction drawing circles with your toes.
- Turn your feet in the same direction drawing circles with your toes.
- Use your fist to gently beat your calf from bottom to top.

Tips for a Comfortable Flight

Remove contact lenses during long flights and use eye drops as needed.

Bring any medication you regularly take into the cabin.

If your ears are blocked or aching, try the following :
·Swallow several times, or have a cough - drop or candy.
·Yawn or open your mouth widely.
Valsalva maneuver can also be tried if above methods do not relieve the ears.
·After blowing your nose, pinch it and blow again with your mouth closed.
(Be sure to blow air gently. Stop the maneuver if it does not relieve the ears after trying two or three times, or if one of the ears is aching.)
Use of a baby bottle or pacifer may be effective for babies.

Nose and throat
Wearing a surgical mask can help ease throat or nasal discomfort.

3. Before Your Trip

Consult your physician
Tips for a Comfortable Flight If you are receiving medical care, be sure to consult your doctor when planning your flight. If you are not confident about your health due to a previous illness or chronic disease, we recommend that you take a medical check before your trip. We also recommend passengers in the late stages of pregnancy or those accompanying infants to consult their doctors. Furthermore, if you fall into any of the DVT risk categories , please ask your doctor whether you are fit to travel and how DVT can be avoided.

Carry your necessities with you
Please check that your carry-on baggage contains any health-related items you may need such as medications, over-the-counter drugs, nasal spray, glasses, etc.
