[Editting for anyone scrolling. I just checked my future flights booked for my wife and/or I, as well as attempted to book a new flight and the seats prices are the same withing the seat class, aisle/middle/window, are all the same. Anyone arguing otherwise is 100% wrong. I travel for work and know more about this than someone who clearly doesn't.]

We're are people paying extra for a window seat? I fly United all the time for work and the seat is always the same depending on the seat class. Economy, preferred economy, or economy plus are all the same regardless of aisle, middle or window.

Their entire claim is bullshit. Also frequent flyers all know the aisle seat is superior.

[Second edit: before anyone wants to leave a dumbass comment explaining why you are wrong and don't understand flight bookings.

1. Go to United.
2. Pretend to book a flight.
3. Select economy. (Not basic economy. There is a bag difference and other restrictions and if you don't understand that then you can just shut up right now.
4. Compare all economy seats. They are all the same.
5. If you go back and select preferred economy, then all the preferred economy seats are the same.
6. This is because when you actually select the ticket based on class then they are ALL the same within the class.
7. If you argue against this point 100% repeatable and proven point then you are a certified moron.
