A Malaysian Airlines plane was forced to turn back on its journey from Kuala Lumpur to Tokyo Saturday, after experiencing problems with cabin pressure. The South China Morning Post quoted Azharuddin Abdul Rahman, the director-general of the department of civil aviation in Malaysia, as saying the plane returned to Kuala Lumpur because “[i]t was not able to maintain the right pressure differential for the comfort of the passengers. It is not a major problem.”

Malaysia’s Star Online reported the flight was 50 minutes into its journey when it turned back. Passengers were subsequently transferred onto another flight, and there were no reports of injuries.

At least one passenger took to Twitter to air his concerns:

Malaysia Airways has been the subject of two aviation disasters in recent months. Flight MH370 from Kuala Lumpur to Beijing disappeared March 8, and has never been found. Flight MH17 was shot down over strife-ridden eastern Ukraine July 17. The death toll from the two incidents was 537.

The airline company’s shares are to be delisted in a $429 million buyout following the two disasters, as Bloomberg News reported. It has also considered changing its name and overhauling its brand to win back consumers, as Forbes said.
