A Thai Airways plane flying from Sydney to Bangkok was forced to make an emergency landing in Bali on Tuesday after a broken cockpit window caused the cabin pressure to drop, according to reports.

Flight TG467 was carrying 272 passengers when it touched down at Bali's Ngurah Rai International Airport at 4.50pm.

There were no reported injuries and the plane's pilot Ivtas Dejkunjorn safely landed the aircraft in Bali, an airport spokeswoman told Daily Mail Australia.

Passengers on the Boeing 747 will fly out from Bali on Wednesday.

Meanwhile in a move to stem losses, Thai Airways International has announced it will cut its executives' transport allowances as it seeks to lift itself out of the red.

The airline posted a financial loss of 12 billion baht (S$467.2 million) last year and is expected to report more losses over the rest of this year, the Bangkok Post reported.
