A 12yo Sydney boy uses family credit card to fly himself to Bali

A 12-year-old Sydney boy has used a family credit card to fly solo to Bali, Indonesia and book a four-day stay in a top hotel, all after a family argument.

While the mother of the unnamed Sydney youngster thought he was at school, he was, in fact, winging his way to Perth on his way to Denpasar, Bali.

The boy, whose story will be told on Australian TV show A Current Affair on Monday, said he looked up which airlines allowed him to travel without needing a letter from a parent. He then tricked his grandmother into giving him his passport.

He used the self-service check-in for his flight to Perth.

Once there no-one at the airport questioned him and he was allowed to fly onto Bali.

"They just asked for my student ID and passport to prove that I'm over 12 and that I'm in secondary school," he told Nine News.

On the Indonesian island, he booked into the four-star All Seasons Hotel, telling staff there his sister would be joining him later.

In the meantime, his mother had reported him missing and said she was "shocked" when she found out where he was.

"There is no emotion to feel what we felt when we found he had left for overseas."
