For the best sleep in Economy Class in 2026, the Window Seat in a row near the front of the cabin is the gold standard. A window seat provides a solid surface to lean your head against and prevents you from being woken up by seatmates needing to use the restroom. Aim for the "mid-front" of the plane (rows 6–15) to stay away from the noise of the engines (which are louder behind the wing) and the high-traffic smells/sounds of the rear galleys and toilets. Avoid the last row, as these seats often do not recline, and avoid bulkhead seats if you are tall, as you cannot stretch your legs under the seat in front. If you are flying in Business Class, look for "staggered" layouts where the seat is directly against the window rather than the aisle to maximize privacy and minimize the "brushing" effect of people walking by in the night.
