Airports are also considered to have some form of a collective choreography: queues that can only function effectively when people have more or less the same speed, circulation-grade areas, not lingering, and unofficial rules that soften the sharp edges of crowds. Majority of the travelers are not attempting to be inconsiderate. The thing is that even minor habits, which are sometimes practiced in absentia, produce their effects which other individuals experience immediately.
These are the silent stressors that are likely to increase the blood pressure throughout the terminal, between the checkpoint and the gate and the last point, along the jet bridge.

1. Arriving to the head of security unprepared
As soon as a traveller starts to undo their shoes, rummage in their podium, find their ID, the queue becomes shorter and the atmosphere is gone. The TSA also promotes the use of waiting time by passengers to empty pockets and organize themselves before stepping up, such as removing items out of pockets and putting them into a carry-on. Smooth security is not speedy rather than sequencing; the bottleneck is created when decisions are made late.

2. The act of making jokes on banned or harmful objects
There are the jokes that work and there are those that freeze the room. The TSA clearly warns that passengers should never joke that they have an explosive device; it will cause an instant rise and ruin the schedule of all of them. The tension is propagated since no one in the checkpoint has a choice of going outside the queue.

3. Leaving phones and small objects loose on the belt
Loose keys, IDs, earbuds and phones are clean, until they fall down between the rollers. TSA advice is that small objects should not be put on top of the X-ray belt as they can be hard to recover or sometimes impossible. When such a passenger happens to stop the line in order to seek something, the rest of the line is subsidizing the error.

4. Allowing a full bottle of water to go to the checkpoint
There is no better sign of restarting the mental checklist than an inability to pass a bottle. TSA observes that a traveler should not carry a bottle of water to the screening area but an empty reusable water container can be transported to refill later. The silent stress is based on the act of unpacking, negotiating or chugging under the pressure in the presence of the line.

5. Medical screening is a kind of something to hide
Insulin pump, glucose monitor and other devices have users who may attempt to walk fast and avoid being noticed, yet the quietness may slow them down. TSA travel guidance has indicated that officers should be informed about a medical device ahead of the screening process and the passengers have the right to request a private screening at any point. Whenever a traveler wavers in the middle of it, the tension is passed on to both the traveler and the individuals in the background.

6. Breaking in queue in a moving walkway, escalator or corridor
Airports reward mass, and a halted flow will cause a little congestion. The most typical one is a traveler and he/she freezes to read a notification, check a gate number or rearrange bags-without moving aside in the first place. Spatial awareness is courtesy and safety simultaneously in a terminal.

7. Before boarding it is called crowding the gate
The gate areas are not often constructed to the entire list of the passengers to create a standing wall. When individuals huddle together, in particular at the same line in the lane before another zone, it obstructs family, close bonding, and those that are attempting to listen to announcements. It seems more comfortable to be outside the plane when the sitting section remains functional and the aisle remains in place.

8. Taking overhead bins as personal storage
The overhead bins are common facilities, and not bonus closet space. Flight attendants have observed over and over that issues begin once passengers pack all their things on top of their heads to create more legroom; personal stuff should be packed under the seat, and bigger carry-ons should have bins. According to the comments of one flight attendant on Condé Nast Traveler, so many passengers put everything in the overhead in order to allow them the space on the ground to stretch their legs and this is the cause of overhead space problem.

9. Leaving bags without paying attention to the plane constitution
The geometry of the bin varies depending on the plane and the right orientation is not universal. According to Delta flight attendant Daniel Compton, there are differences in the way overhead bins are used across fleets: in our A321 CEO fleet, the suitcase should be packed lying down; on our A321 NEO, the luggage is packed on its side. Once a traveler pushes a bag in the wrong direction the micro-drama impacts the whole boarding process.

10. Requesting crew to pick up a bag and put in the bin
Numerous passengers believe it is a regular demand, but the crew does not always have time to lift luggage because of safety regulations and the risk of injuries. Compton has indicated that the flight attendants are glad to give tips, but, We do not carry your suit-case unless you have a condition or reason you are unable to. The stress consists in the standoff situation where everyone is waiting to have one task completed in a small aisle.

11. Sound broadcasting, music, calls, videos, into common air
Announcements, rolling wheels, overlapping conversations are already buzzing in the airports. The inclusion of the speakerphone audio puts the strangers within the soundtrack of another person and increases fatigue rates quickly. Headphones are not a nicety; they keep the gate out of the way of being a competing set of personal sound stages.
There is very little about being polite in an abstract way in regard to airport etiquette. It concerns safeguarding flow, by checkpoints, corridors, lanes at the boarding gate, the aisle of the aircraft, in such a way that minor delays do not accumulate to group stress. When passengers make common areas seem like common systems, the terminal will appear as less an ordeal and more a place as it should be a point of transit between destinations.
