If you are a frequent flier, you may dread the thought of another long journey squashed up inside a pressurized cabin with hundreds of other people. The possibility of falling sick during and after a long flight is actually quite high, every year many people suffer illnesses as a result of not adequately preparing for their flights. If you have a long haul trip coming up, the following tips and advice should help to ensure that you arrive at your destination without suffering any adverse effects.

One of the golden rules when flying is to keep yourself hydrated. The air in an aircraft's cabin is extremely dry, it can quickly suck the moisture out of your body. It is important that you drink a lot of fresh water in the hours leading up to your departure, and continue to do so when on board. Though there can be the temptation to partake of free alcoholic beverages when in the air, doing so you will only increase the dehydration effect.

Airplane food can hardly be called healthy. For this reason, it can be desirable if you were to carry your own snacks and prepared food on to the flight. Though there are strict controls over taking liquids on to aircraft, there is no regulation governing solid food. That being said, you should understand that it can be an offense to try and carry food into your country of arrival. Eating well is also good for the spirits when stuck twenty thousand feet in the air.

Try and get a good sleep the night before you leave. If you have an early morning departure, it can be worth booking a hotel room close to the airport so that you do not have to travel during the night. What's more, you should do all your packing twenty four hours ahead of schedule, do not leave it to the last minute.

If you have an MP3 player or similar portable entertainment device, carry this in your hand luggage. Being able to listen to your favorite tunes or watch the movies of your choice can help the time to go faster when on board a flight. If you were to rely on the airline's entertainment system, you may quickly get bored.

On a final note, remember to exercise during the trip. You should get up form your seat every two or three hours and walk up and down the aisle a few times. Promoting blood circulation can help to fend off various flight related sicknesses.
