This meant all the toilets on the left-hand side of the plane were rendered unusable as they have an interconnected system."With 220 passengers on board, continuing the flight was unfortunately not an option," they added.The airline's dispatch center "immediately organized a replacement aircraft with a new crew," the spokesperson said. This meant the passengers landed in Washington, DC, with a delay of just under five hours.While flights to nowhere can be frustrating for passengers, this incident shows how returning to a hub airport can provide better solutions than continuing. It is easier for airlines to reroute passengers, find new crew, and repair any issues at one of their hub airports than if they divert somewhere closer to the destination."Such a delay is of course very annoying for our passengers and we would like to apologize again for the inconvenience," the airline spokesperson said."In such situations, we do everything we can to get our passengers to their destination as quickly as possible," they added. "This is always our top priority."This is the second time this month that a flight has turned around due to faulty bathrooms.An Air India flight returned to Chicago in a nine-hour ordeal after bags, rags, and clothes had been flushed down toilets and clogged the Boeing 777's plumbing.
