I am sitting on kbin, opened your post and wrote this comment. Also giving you an upvote.
It’s a fediverse thing as long to instances talk the same protocol they can interact from within the fediverse no matter what instance .
Edit: protocol not language
Get chewing gum and take one on take off and later descent, it helps with pressure release for the ear’s.
Don’t get worried about the noise the aircraft makes when flaps or gears travel.
If the flight is longer try to get a place at the walkway , you could stretch the legs out.
It’s is nicer to sit in front of the wing area, less noise and flight path changes are more easy to handle.
Don’t sit near toilet’s, smell and traffic during flights.
