Here are the key facts extracted from the text:
1. Airlines have dress codes that vary depending on the destination and can result in passengers being denied entry onto the plane.
2. Cell phones should be put on airplane mode during a flight to avoid interfering with the pilot's equipment that use the same radio frequencies.
3. Someone hacked into the plane's PA system and made strange noises for the entire flight in September 2022.
4. Littering on planes is bad for the flight attendants who have to clean up the trash, which can include dirty diapers, used catheters, and bottles of pee.
5. Some people bring their non-service pets on board as service animals, such as horses, peacocks, and pigs, but a new law banned all service animals other than dogs from flying.
6. A man caught a wild Egyptian cobra and brought it on board in his hand luggage in 2012, but it bit him and escaped into the cabin, causing an emergency landing.
7. Tea, coffee, and ice on planes are made from water tanks that are often old and full of bacteria, so it's better to stick to bottled drinks.
8. Alcohol can have a stronger effect on planes due to the lower oxygen levels in the cabin, and being drunk on a plane is a criminal offense.
9. Lithium batteries are inside many devices and are sensitive to high temperatures and flammable, so they should be kept in hand luggage not main luggage.
10. Plane cabins are dry and can dehydrate your eyes, which can cause problems for contact lens wearers, such as tearing their cornea or getting infections.
