The idea of airplanes is that common politeness has been engineered into some sort of engineering issue: there is not enough space, and the timing is fixed, and there is a crew operating under a tightly scheduled program of inspections and service. Good intentions may cause friction in that system, sometimes to the crew, sometimes to the people in the next row, and frequently to all those who are trying to get out of the building on time.
Words like courtesy are less likely to be used by flight attendants as doing extra and more as a way of not interfering with the workflow that they are trained to handle. Flight attendant Tania M., who is nearly 20 years old in the cabin, said it: We do like it when people go out of their way to be helpful. usually. Most of the inflight etiquette is found in the usually.

1. Policing other passengers
A correction of a stranger concerning seatbelts, masks, or any other regulations can be civil-minded, but it creates tension in the limited area where one has no medium of escape. The crew is the only group trained and authorized to manage compliance and it is their task to determine what reminder is suitable, or maybe a personal warning is better or to adopt a variant of intervention. A secret communication to a flight attendant helps to maintain the calmness and hold responsibility in a proper place.

2. Rebelting the overhead bins as a jigsaw
Moving a bag that does not belong to somebody, stirring coats, or repairing a bin in order to create a place so that it can be brought easily results in misunderstanding that extends to the landing where individuals are unable to locate what was relocated. The etiquette is improved, quick, intimate, and compact: carry up and down his own bag, shut the bin, and get out of the aisle. Aircraft can vary when it comes to orientation leaving some with suitcases stacked on their side and others fitted better on their back some aircrafts have their overhead bin stowage instructions showing this variation.

3. Touching attention
A tap may feel softer than shouting yet a great number of crew members have undergone multiple touching during a shift and most of it is not well received. It is done without crossing the line by a mere, Excuse me, eye contact or even the call button. In the U.S, it is taken seriously to interfere with the duties of the crew member; the best thing to do is to keep hands to self and use words or call system.

4. Asking to have the water-bottle filled up in half-way
Reusable bottles are feasible, however, cabin water is scarce and it is supposed to be used to sprinkle the entire plane. Tania M. described the limitation in simple terms, namely: we simply cannot fill all of your water bottles, and you would not have enough to give. It is topped after security and serves on the regular cup service onboard, which makes the supply predictable to all.

5. Pulling a drink from the cart
Getting a soda or snack at the cart may seem to be an efficient action but the act upsets inventory flow and crunches people into the aisle just when the crew is trying it to stay clear. The cart also is a controlled workspace controlled service line, part safety corridor. A wait is not waiting passively, it is collaboration with a mechanism that ensures movement is not disorganized.

6. Delivering trash that is hazardous
Tissues, diapers, and anything contaminated with body fluids must not be put directly in the hands of a member of a crew. The best place to discard the majority of it is lavatory trash and those who have medical sharps should always have a proper container and disc it once they get to their destination. The retention of waste within the confines of the ship and not directly handed over to the crew or other passengers is beneficial in that it keeps the crew and the rest of the passengers safe.

7. Protecting dumpster space by being too careful with the stowing
The continuous repositioning of a carry-on or actual blocking of surrounding space will bring the boarding process to a crawl and encourage confrontation. The cabin is most effective when every passenger considers the overhead to be a communal infrastructure and not a storage space. A common sign-rule among cabin crews is to store personal belongings under the seat so that larger baggage can be carried on board, above, which is emphasized in the general rules of using overhead baggage in the crowded airplane.

8. Making the call button sound more like a small-talk delivery
The button is real and has real needs, but it is not a gadget that helps to talk and relieves boredom. Cabin crews are dealing with safety checks, paperwork, cockpit coordination, and timing of the service, and they usually have all of this at the same time. In the cases where the waiting is possible, the majority of attendants would prefer that passengers come to the galley after the service instead of forming a line of lights across the cabin, which is reflected by the superb set of dos and do nots of the call bell.

9. Reserve thanks to the cockpit alone
The pilotes can be seen at the door, whereas the cabin crew did most of the continuous, face-to face work in this day: the safety briefs, surveillance, service and problem solving at the seat level. When the passengers send their thanks to the cockpit it quietly removes the faces behind the moving parts of the cabin. It does not cost anything to thank the attendants on the way out with a simple thank you that considers the entire chain of care.
Etiquette in the airplane is not about being the most helpful person in the plane but rather not to tamper with a system that already has to operate within very constrained parameters. Even minor improvements such as putting away tidily, keeping hands to self, service flow respect, shrink bottlenecks like good design.
As passengers support their positive intentions with the workflow of the crew, the cabin becomes peaceful, boarding is smoother, and everyone comes to the airport without many crumpled ends.
