4. Your flight crew only get paid when you're in the air
For reasons stipulated in those collective bargaining agreements you hear about during airline strikes, pilots and flight attendants only get paid for the hours the plane is in the air. Meaning, it’s not their fault if your flight’s been delayed or you’re stuck sitting on the tarmac. So be nice, wouldja?
5. Airplane air is quite literally as dry the Sahara
You may have noticed how your hands get dry and your throat feels like sandpaper when you fly. That’s because the pressurized air in the cabin is kept below bone-dry 20% humidity -- just about the average humidity of the Sahara.
6. You lose 8 ounces of water from your body for every hour you fly
That dry air saps the water from your body, to the tune of about 8 ounces an hour. Which, if you do the math, is roughly a two-liter bottle during a 10-hour long-haul flight. Stay hydrated, friends.
7. Dimming the lights for takeoff and landing isn't a mood effect
It’s done so passengers’ eyes can adjust to the dark, just in case there’s an emergency that shuts off the lights. That way people aren’t running around blind in sheer chaos.
