A woman whose scarf was urinated on by a drunk Jetstar passenger says the flight attendant "giggled" when she complained.
Jessica Kay says she has had to throw her sodden scarf out and that it took 20 minutes for anyone to respond to her calls for assistance on the Auckland-Singapore flight.
The urinator received a captain's warning and faced no criminal charges after emptying his bladder on a man, Ms Kay's scarf and the carpet.
The Auckland woman said it "wasn't the best flight", adding: "When I pressed the buzzer for assistance it took a long time, about 20 minutes, for anyone to come.
"I got given a sick bag and I asked for the urine to be cleaned up but the air hostess giggled and never came back."
She said it was clear that there was no communication between staff, as the attendant did not appear to realise a man had urinated in the aisle.
"I would not choose to fly Jetstar again and I have chucked the scarf away. I was disappointed that Jetstar ... didn't clean up the urine in the aisle."
Jetstar spokeswoman Jennifer Timm said the offending puddle was cleaned up when the plane landed in Singapore. She said all Jetstar planes are cleaned professionally.
The plane had a turnaround time of 1 hours in Singapore, she said.
She added that Jetstar once again apologised for any disruption to passengers and was in the process of contacting customers affected by the urinator to offer compensation.
Another passenger said he was surprised police did not get involved when the plane landed.
Singapore criminal lawyer Josephus Tan said the urinator could have faced a number of criminal charges if the Singapore force had been called. He said that, on the surface, it seemed that the urinator could be charged with "drunkenness in public places" or "riotous, disorderly or indecent behaviour".
These charges had been brought in previous cases where people had exposed themselves in public, he said.
First-time offenders pleading guilty to these offences usually received a fine. However, if there was a specific female target involved, the urinator could face up to a year in jail and/or a fine, he said.
Under New Zealand law, public urination could be legally classified as offensive behaviour, with transgressors facing a maximum of three months' jail or a $1000 fine.
