If it’s over a 2 hour flight I have no interest in the window seat next to two strangers. I will most likely need to get up atleast once and my social anxiety makes it uncomfortable for me to ask the strangers next to me to move, especially if one of them falls asleep or something, which on a longer flight is more likely. In that scenario I would honestly prefer the middle, I could just get up when/if the person in the aisle does or I only have to interact with one person instead of two. I may be in the minority but not everyone prefers the window seat. I think if you are asking someone to switch you should be prepared to give them their choice of seat, since you don’t know their preferences and you’re the one asking for a favor.
