An Australian woman is trying to get around the airline’s rules about where she can travel, buying an Alaska plane from Beijing to Beijing and then returning home.
The woman, who asked not to be named, travelled to the city of Xian on the Chinese mainland in June.
She paid a fee to fly from Beijing, but returned to Australia after five days, without incident.
“I’ve got three months until my departure and I have a flight out of Beijing,” she said.
“That was my only reason for going to China, and I didn’t think it was illegal.”
Alaska Airlines flight rules allow passengers to buy tickets online or by mail.
But the airline says it is still a good idea to book ahead and check in at the gate.
“You can book a ticket online or in person.
You can book in advance online and you can book by mail,” said Alaska Airlines spokesperson Jennifer O’Connell.
Allegations of fraud are common, but this time the woman travelled with no documentation.
Her flight was booked through a website called Alisa.com, which was also owned by Chinese-owned Chinese airline Shanghai Air.
“The website we use for booking flights in China is owned by Shanghai Air and Shanghai Air’s customer service team is working with Alisa to resolve the issue,” Ms O’Connor said.
In a statement to ABC News, Alisa said: “We are aware of the complaint and have taken the issue seriously.
We are currently investigating this and have requested the airline to provide an explanation.”
But Ms O`Connell said the company had received no complaint from the woman, and no charges had been laid.
“There are very few instances of this kind of issue,” she told ABC News.
“It’s one of those things where it’s just an incredibly stupid way to get an international flight.”
The woman, from Perth, said she hoped to get back to China and start her new life.
China’s aviation industry has been under increasing scrutiny in recent years.
China has one of the highest suicide rates in the world, and many have blamed a lack of safety precautions in the country.
The International Civil Aviation Organisation (ICAO) last year reported an increase in the number of people dying on air travel to nearly 9,000 per year.
A new crackdown on airline fraud in China came after the death of a teenage girl in September who was allegedly recruited for a fake job and then paid for her services.
