Are you asking me?
Ok, example is you want me to switch seats so that you can sit next to your child. You'd be asking me to concede something for your needs.
Fair enough. And I think depending on the age it could be a desire rather than a necessity, but I see your point.
If you wanted to sit next to someone you were flying with, i would give you my seat if asked nicely.
Ive done it in the past.
Definitely not a need, but nice nonetheless.
someone with a bladder issue who needs to be near the restroom or with a phobia with similar needs
Again, not really a need, as an extra 10 seconds to the restroom won't make it or break it in 99.9% of cases.
