no introductions just a greeting

No. I don't even say hi.

引用自 Husky：

Do you introduce yourself to the passenger next to you in a plane?

we live in a world where next door neighbors don't even know their names

Someone introduced themselves a person when they requested they sit beside the window that was dedicated to the ticket in my hand as the seat requested months in advance without a passenger. So they could not have to sit next to their people against a window.

Have not taken another flight since, cannot afford lord knows why being subjected to such animosity during a plane ride.

The answer is step with ticket in hand no baggage or carry on unless include the coat. Slip mask over eyes and throat and just feel how it is to float. Gonna be kidnapped might as well be rested.

depends on the NPC

I have never been on a plane, I have been on subway train, mostly keep to myself, being alone and all, sometimes I look at other passengers to guess what's their reasons for traveling.

i belch and fart loudly, then stare at them to establish dominance V:

you stare at them?

No. I listen to headphone or read.

I say hello at the most. If they seem to want privacy, I don't even say that.

that's the worst part of flying
pilot farting in the front, flight attendants farting and smiling at everyone over there, people farting every seat and next to you and nowhere to go, just breathe and enjoy
sometimes the pilot says there's going to be a little air turbulence, yeah ofc

Why in God's name would I do that?

i'm now reminded of the waterpark episode of south park

Nope, just a greeting and some small talk unless they seem interested in talking, albeit the last time I was on a plane was 18 years ago or so.
