Virgin and Etihad planes are parked next to each other at Kingsford Smith airport in Sydney August 30, 2013. Virgin Australia Holdings Ltd reported a A$98.1 million ($87.6 million) full-year net loss on Friday, blaming difficult economic conditions, strong competition and one-off costs related to its recently acquired Skywest business. It also said major shareholders Air New Zealand, Etihad Airways and Singapore Airlines had agreed to provide a term loan worth A$90 million. The result contrasts with a well-received full-year net profit of A$6 million reported by rival Qantas Airways Ltd on Thursday. Reuters/Daniel Munoz

A Sydney-bound Virgin Australia flight was forced to return to Los Angeles on Tuesday after passengers complained of a very strong and foul odor while flying.

Passengers described the smell as unbearable, making some of the air travelers think that human waste had seeped into the aisles. However, Virgin Australia denied that it was poop that caused the stench.

It explained the incident to two leaking sinks on Flight VA2 that was scheduled to leave LA at 7:55 pm on Monday and return to LAX on Tuesday at 4:09 am.

Virgin Australia took care of the overnight accommodation of the passengers in LA and said it would do its best to bring them to Sydney and their other destinations as soon as possible.

BBC quoted a passenger named Julia Malley who insisted that it was obviously human waste that was seeping thought the aisles. But Virgin denied her claim, saying that its toilets have a separate drainage system and pointed to the leaking sinks as the source of the stink.
