Air Pressure Solutions

.
Bring gum along with you. When you are taking off, chew it. Another way to help with air pressure is to blow with your hand over your nose and mouth. Plus one more - swallow and yawn.

Airplane Temperature:-
.
Because of the altitude, airplanes can be quite cold (especially the floor). I always take a jacket with me on the plane and take one of the blankets that the airline provides. Wool socks are not a bad idea either. On the larger planes, there is usually a little fan that blows on you. The airflow can be adjusted by twisting the unit.

Aisle Seat or Not?
.
When traveling by air in high risk areas, always request a window seat. If the flight is high-jacked, terrorists tend to hit the people sitting on the aisles as well as pull out people in aisle seats for mistreatment. It pays to be harder to get to! This may sound extreme but living in South America it is something I always practice.
