On the vast majority of commercial aircraft, pilots do not have a dedicated private toilet; instead, they share the forward lavatories with premium cabin passengers. However, on certain ultra-long-haul aircraft like the Airbus A350-1000 or some Boeing 777-300ER models, there is a small lavatory located within the secure cockpit area or the crew rest compartment specifically for the flight crew's use. For standard flights, when a pilot needs to use the "head," a strict security protocol is initiated. A flight attendant must block the aisle with a galley cart or their body, and a "double-door" procedure is often used to ensure the cockpit remains secure at all times. In 2026, some newer wide-body designs are incorporating "crew-only" facilities to minimize the time the cockpit door is open, which enhances both safety and pilot privacy during 15-hour "marathon" flights.
