Air India faces problems with clogged toilets on long-haul flights due to passengers flushing inappropriate items. This has caused several flights to divert or return. Engineers and crew members suggest improvements to lavatory facilities and better passenger education to prevent such issues.

Images available with NDTV show a large cloth being removed from a tube attached to the lavatory system on board AI-126, the Boeing 777-300ER which had to return to Chicago on March 5 after the majority of its lavatories on board were choked.
