1. Be mindful of personal space: Respect the space of your fellow passengers by avoiding unnecessary physical contact, such as leaning on or crossing into their seating area.
2. Keep noise to a minimum: Use headphones when listening to music or watching videos, and speak softly when conversing with others. Avoid loud conversations or disruptive behavior that may disturb those around you.
3. Recline your seat with consideration: Before reclining, check if the person behind you is using a tray table or has limited legroom. If so, it's courteous to either ask for their permission or recline your seat partially to provide them with more space.
4. Follow the lavatory etiquette: Be mindful of the time you spend in the lavatory, especially during peak hours. Avoid leaving a mess and ensure you leave the restroom clean for the next person.
5. Observe the overhead bin space: Only use the overhead bin space above your own seat for your carry-on luggage. Avoid hogging space by placing items in bins far away from your seat.
6. Be considerate when getting up: If you need to use the restroom or stretch your legs, be mindful of your neighboring passengers. Try not to grab onto their seats for support and avoid stepping on their belongings.
7. Practice good hygiene: Maintain cleanliness by using hand sanitizer or washing your hands before eating. Avoid strong-smelling foods and be mindful of personal hygiene, especially in close quarters.
8. Follow the rules of the flight crew: Listen attentively to the instructions provided by the flight attendants and follow their guidelines regarding safety procedures, electronic devices, and other regulations.
9. Be patient and courteous: Remember that everyone on the flight has their own needs and schedules. Practice patience and kindness towards fellow passengers and the flight crew, especially during potential delays or challenging situations.

These are just a few examples of the unspoken rules of airplane etiquette. By following these guidelines, you can help create a more pleasant and comfortable travel experience for everyone on board.
