Air India has confirmed that one of its flights from the US was forced to turn around last week after passengers trying to flush away plastic bags, rags and clothes clogged up most of its toilets. The plane, which was heading from Chicago to India's capital Delhi, spent several hours in the air before it returned to the US city.

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.
