Ann Kristin Balto, from Tromsø, said that the flight stopped shortly after she alerted cabin staff to the leak she had spotted and photographed as the plane was on the way to the runway at Bangkok airport.
"We started to point out the window, so that the the stewardess became aware of it, and she looked out of the window and picked up the phone. I don’t know who she called but the plane stopped immediately afterwards," she told The Local.
The passengers were put up in a local hotel and then put on the next available flight out, eventually arriving in Oslo 19 hours late.
Norwegian's press spokesman Charlotte Holmbergh Jacobsson confirmed the leak to Norway's Nordlys newspaper, but stressed that the passengers had never been in any danger, and that the pilot would have been aware of the leak from his instruments.
"Yes, it is leaking fuel and it was noticed very soon after the aircraft starting taxiing out," she said of the photographs. "There was never any danger to the passengers."
Balto said that most of her fellow passengers were sympathetic to Norwegian, with few blaming the airline for its problems.

"The passengers discussed this when we were in Bangkok, staying in the hotel so that we could have a rest before we went the second time," she said. "The passengers weren’t angry at Norwegian, but felt more that Norwegian has unfortunately been put into a very difficult situation by buying these Dreamliner planes."
"They sell cheap tickets, that's something else to think about it," she added. "Now it’s possible to get to Bangkok for half the price, and it’s a direct flight from Oslo."
