The relatively low air pressure in your aircraft can cause discomfort. Cabin pressure if equivalent to that at 8000 feet above sea level. If your ears bother you during takeoff and landing, try yawning, chewing gum or doing this: pinch your nostrils shut, inhale, close your mouth and try gently to blow your nose.
The air in the cabin will be very dry. Accept all of the flight attendants’ offers of free beverages. – choose plain non-carbonated water or fruit juices instead of caffeinated or alcoholic drinks, which will dehydrate you.
If your eyes begin to smart, remove your contact lenses and wear glasses. Unscented air moisturisers are available in aerosol form. Use one periodically to spray your face and the air in front of your face for a refreshing pick-me-up.
If you’re not crazy about airline food, take a tip offered by well-travelled people – order the vegetarian meal. This tends to be usually more attractive and delicious , perhaps because it’s specially made, than the regular meals served.
