Aisle seat or window seat?
Window gets the wall, the view and control of the shade. Aisle gets the bathroom, the overhead bin and two inches of freedom. The Judge rules. Below: both sides as they'd actually put it, then the ruling The Judge gives when two people bring this one into a Settle It room.
Both sides
Window. A wall to lean on, a view, and no drink cart in your elbow. Nobody climbs over you. It's the only civilized seat.
Aisle. I stand up when I want, I get off first, and I'm not asking two strangers for permission to use the bathroom on a six-hour flight.
The Judge's ruling
Ruling: Both of you are describing the right seat for a different trip. Under three hours, or overnight when you plan to sleep, the window wins: the wall is a pillow and nobody wakes you. Over three hours in daylight, the aisle wins: freedom of movement beats a view of clouds you stop looking at after ten minutes. The window seat also gets sole custody of the shade, which the aisle has historically resented.
Sentence: Short and overnight flights: Kai gets the window. Long daytime flights: Zoe gets the aisle. The middle seat goes to whoever booked last. This ruling is binding on all future trips and may be read aloud at the gate.
