On Delta, the 737-800 (73H) has a litany of windowless windows, but in different spots: rows 13, 15, and 16, with several surrounding rows sporting paltry partial windows. Yet, as with the preferred seats on AeroMexico, these rows are classified as Comfort+, upgradeable from standard economy.

On the Boeing 737-800, the most notorious "window seat without a window" is typically located in the front half of the cabin, specifically at Seat 11A (and often 11F) or Seat 12A/F, depending on the specific airline's configuration. This missing window is a result of the aircraft's design, as the space within the fuselage wall at that specific location is utilized to house essential air conditioning riser ducts that carry air from the belly of the plane to the overhead vents. While most passengers book these seats expecting a view, they are instead met with a solid plastic wall. Some airlines, like Ryanair, have this gap at Seat 11A, while others like United or American may have it slightly shifted due to different seat pitches. It is always highly recommended to check a site like Aerolopa or the airline's specific seat map before booking if you have claustrophobia or simply want to enjoy the view, as these "blind" seats are rarely discounted despite the lack of a window.
