The Boeing 777-300 ER aircraft had to be grounded due a hydraulic failure in one of the aircraft engines, the spokesperson said.
"All passengers had boarded the aircraft and it was ready for departure when problem in the engine was detected," said a stranded flyer.
The engineers were called in to fix the glitch and make the aircraft airworthy but to no avail, the passenger said.
"We remained seated in the plane till around 6 AM. Later, the airline staff shifted us to a hotel," the passenger said.
