In a standard narrow-body aircraft configuration (like a Boeing 737 or Airbus A320) with a 3-3 seating arrangement, Seat A and Seat F are the window seats. Seat A is located on the far left side of the plane (when facing the cockpit), and Seat F is on the far right side. In larger wide-body aircraft (like a Boeing 777 or 787), Seat A remains the window seat on the far left, while the far-right window seat might be labeled Seat K or Seat L depending on the width of the cabin. For those who enjoy photography or want a wall to lean on for sleep, A and F are the most coveted spots. A grounded peer observation: if you are sitting in Seat A, you are typically looking out over the "port" side of the aircraft, whereas Seat F gives you a view from the "starboard" side. In 2026, if you see "1A" on your boarding pass, you are in the very first row on the left side, which often provides extra legroom but requires all personal items to be stored in the overhead bin for takeoff and landing.
