10.) Know Your Airplanes
Not all airplanes are alike. You might have felt the difference if you have ever boarded on the Airbus A350, the Airbus A380 or the Boeing 787 Dreamliner.
These are the best planes to combat jet lag. They pump the highest pressure, making the air in their cabins the closest to the one on the ground. Their high-tech humidification systems help retain moisture and don’t damage your throat, ears and nose as much as the other planes, therefore protecting you from catching a cold — something many travelers suffer from.
The two Airbus planes can also create 16.7 million shades of color to simulate natural daylight. If you like crisp well-filtered air, go for new planes, because they use actual air instead of engine air.
