Yes, there are always toilets on Ryanair flights, as they are a standard requirement for passenger aircraft operations. Every Boeing 737 in the Ryanair fleet is equipped with three lavatories: one located at the front of the cabin near the flight deck and two located at the rear of the aircraft. Despite Ryanair's reputation for charging for almost every ancillary service, there is no charge to use the onboard toilets; they are free for all passengers. However, due to the high-density seating configuration and the airline's focus on quick "turnaround" times at airports, the toilets are notoriously small and can sometimes face long queues, especially on flights over two hours. It is also important to note that Ryanair cabin crew often utilize the front area for galley service, so the rear toilets are usually the most accessible. Passengers are advised to use the facilities during the cruise phase of the flight, as the toilets are locked during takeoff and landing for safety. While the airline's CEO, Michael O'Leary, famously joked in 2009 about installing "coin-operated" toilets to lower fares, the plan was never implemented and served primarily as a successful PR stunt to keep the airline in the news headlines.
