Frankfurt-bound AI 121 was carrying 214 passengers and the flight was supposed to take about eight hours. The plane returned to Delhi about three hours after it had departed. Passengers aboard the plane were supposed to be offered two full meals, a snack and unlimited beverage service.
"The flushes were unserviceable so the plane had to return to Delhi," an Air India official told the Times of India. "The passengers could not board another aircraft since night curfew in Frankfurt would have kicked in by the time the alternate plane would have reached there."
Another Air India plane experienced a similar problem when "everything made available to passengers for free was found flushed down the toilet."
Apparently passengers flushed complimentary blankets, pillows, socks, slippers and towels down the toilets, causing them to clog.
I think the crew didn't want to fly on this AI flt. Who chucks blankets in the toilet when you can smuggle them out? http://t.co/t2cxizwvyM— ranjona banerji (@ranjona) June 2, 2014
"AI is the oldest airline of the country," an airline official said. "It should know the behavior of Indian passengers and should maintain toilets accordingly. The failure to do so has cost the airline dearly, both monetarily and in terms of losing flyers' faith."
It's unclear what caused the toilets aboard flight AI 121 to clog.
