• With the exclusion of service dogs, live animals of any description are NOT PERMITTED IN THE PASSENGER CABIN, and are not applicable to interline through check. In all cases (except services dogs, which are permitted to travel free of charge), the animal will be treated as excess baggage for which you will be obliged to pay the applicable rate. Excess baggage charges will be assessed on the basis of the total weight of the animal and its container.
• Please ensure you obtain all necessary permits to enable the animal to enter the country / territory of destination (including transit). Cathay Pacific Airways will not be responsible in the event of the animal being refused entry into, or passage through, any country / territory. You as the owner assume all risks of injury to (or sickness or death of) the animal.
• In view of aircraft safety, we will not accept fighting dogs for carriage on all our flights.
  

Humidity levels of less than 25 percent are common in the cabin. This is due to the extremely low humidity levels of the outside air supplied to the cabin. The low humidity can cause drying of the nose, throat and eyes and it can irritate wearers of contact lens.
We recommend that you:

• Drink water and juices frequently during your flight.
• Drink coffee, tea and alcohol in moderation. These drinks act as diuretics, increasing the body's dehydration.
• Remove contact lenses and wear glasses if your eyes are irritated.
• Use a skin moisturiser to refresh the skin.

It is necessary to pressurise the outside air drawn into the cabin to a sufficient density for your comfort and health. Cabins are pressurised to a maximum cabin altitude of 2440 metres.
The cabin pressure and normal rates of change in cabin pressure during climb and descent do not pose a problem for most customers. However, if you suffer from upper respiratory or sinus infections, obstructive pulmonary diseases, anaemias or certain cardiovascular conditions, you could experience discomfort.
Children and infants might experience some discomfort because of pressure changes during climb and descent.
If you are suffering from nasal congestion or allergies, use nasal sprays, decongestants and antihistamines 30 minutes prior to descent to help open up your ear and sinus passages.
If you have a cold, flu or hay fever, your sinuses could be impaired. Swollen membranes in your nose could block your Eustachian tubes - the tiny channels between your nasal passages and your middle ear chamber. This can cause discomfort during changes in cabin pressure, particularly during descent.
Recommendations:

• If you have a pre-existing medical condition that warrants supplemental oxygen, you can order it from us. Please give at least seven days' notice before travelling.
• To 'clear' your ears, try swallowing or yawning. These actions help open your Eustachian tubes, equalising pressure between your middle ear chamber and your throat.
• When flying with an infant, feed or give your baby a dummy during descent. Sucking and swallowing will help infants equalise the pressure in their ears.

The main cause of jet lag is travelling to a different time zone without giving the body a chance to adjust to new night and day cycles. In general, the more time zones you cross during your flight, the more your biological clock is disturbed. The common symptoms are sleeplessness, tiredness, loss of appetite or appetite at odd hours.
To try to minimise the effects of jet lag, we recommend that you:

• Get a good night's rest before your flight.
• If possible, give yourself a day or two to adjust to the new time zone after arrival.
• Fly direct to minimise flight time, if you can. This allows you to relax more upon arrival.
• Try some light exercise, go for a brisk walk, or do some reading, if you can't sleep after arrival at your destination. It generally takes the body's biological clock approximately one day to adjust per time zone crossed.
  
  

When you're sitting upright and inactive for a long period of time, several things can happen:

• The central blood vessels in your legs can be compressed, making it harder for the blood to get back to your heart.
• Muscles can become tense, resulting in backaches and a feeling of excessive fatigue during, and even after your flight.
• The normal body mechanism for returning fluid to the heart, can be inhibited and gravity can cause the fluid to collect in your feet, resulting in swollen feet after a long flight.
• Some studies have concluded that prolonged immobility may be a risk factor in the formation of blood clots in the legs, deep vein thrombosis (DVT). Particular medications and medical conditions may increase the risk of formation of blood clots if associated with prolonged immobility.

Medical research indicates that factors that may give you an increased risk of blood clots in the legs include:

• Personal or family history of DVT.
• Recent surgery or injury, especially to lower limbs or abdomen.
• Blood disorders leading to increased clotting tendency.
• Immobilisation for a day or more.
• If you are aged above 40 years.
• Oestrogen hormone therapy, including oral contraceptives.
• Pregnancy.
• Tobacco smoking.
• Former or current malignant disease.
• Obesity.
• Dehydration.
• Heart failure.
• Varicose veins.

Recommendations:

• If any of these categories apply to you or you have any concerns about your health and flying, we recommend you seek medical advice before travelling.
• Compression stockings can assist in preventing swelling of the ankles and feet and they may improve the blood return to the body from the lower legs. You may like to talk to your doctor about this. The stockings may be purchased from medical and surgical supply companies and will need to be individually fitted to your leg measurements.
• While inflight, move your legs and feet for three to four minutes per hour while seated and move about the cabin occasionally.
• Do the light exercises recommended below in the Inflight Workout section.

This ailment is caused by a conflict between the body's sense of vision and its sense of equilibrium. Air turbulence increases its likelihood because it can cause movement of the fluid in the vestibular apparatus of the inner ear. If you have good visual cues (keeping your eyes fixed on a non-moving object), motion sickness is less likely to occur.
Recommendations:

• When the weather is clear and you can see the ground, sea or horizon, you are less susceptible to motion sickness.
• You can buy over the counter medications but we recommend that you consult your doctor about the appropriate medications.
  

Cosmic radiation is the collective term for the radiation that comes from the sun and from the galaxies of the universe.
The earth's atmosphere substantially shields the earth from cosmic radiation. However the dose of cosmic radiation increases with:

• increasing altitude,
• length of the flight, and
• increasing latitude (getting closer to the north or south pole).

Like radiation from other sources, cosmic radiation is measured in sieverts (Sv). Annual doses are measured in millisieverts (mSv) which are thousandths of a sievert. Measurements on China Eastern aircraft on individual sectors are measured in microsieverts (uSv) which are millionths of a sievert.
All humans are exposed to background radiation at sea-level. This comes from sources such as the local environment, food and drink, medical exposure and building materials. In high doses, radiation can be harmful. However, the doses received at flight altitudes are considered very low. The world average background radiation level is 2.4 mSv per year and the average Australian dose is approximately 2 mSv each year.
