Confidently incorrect.
Lol I literally just checked for you. Not only is the middle seat cheaper, but the aisle seat is more than the window seat. Picked a large cross-USA trip to make sure it'd have triple seats.
JFK-LAX
Jan 18, 2026
Basic as can be to make sure no upcharges were included
Picked whatever flight was first
787-9, dual aisles with 3 triple seats across.
Aisles are the same across a row, middles are the same as well, regardless of middle triple or side triple
Row 45 (preferred eco) Window is +$70, aisle is +$54, aisle is +$86
Row 55 (eco) window is +$30, middle is +$23, aisle is +$36
Meanwhile, you're being unnecessarily condescending about wanting a window seat. It's preference. Good for you and your jetset life. I like window seats, that's all.
