A Singapore Airlines plane was forced to make an emergency landing in Azerbaijan due to loss of cabin pressure.
The Airbus A380 plane was flying from London to Singapore and had 467 passengers and 27 crew members on board.
Singapore Airlines said that oxygen masks were deployed and the aircraft landed “uneventfully” at the Baku airport.
It said that none of the passengers or crew was injured and that it was investigating what caused the problem.
Singapore Airlines said a replacement airplane to take the stranded passengers on to Singapore had now departed and was due to arrive in Baku on January 7.
It said it had also sent staff from both Istanbul and Moscow to provide assistance on the ground in Baku.

However, some customers writing on the airline’s Facebook page complained about the wait for a replacement plane.
In response to the complaints, Singapore Airlines issued a statement on Facebook apologizing: “We sincerely apologize to affected customers for the inconvenience caused by the diversion and the lengthy delay encountered at the airport in Baku.”
However, other people writing on Singapore Airline’s Facebook page praised its handling of the incident.
In response to passenger reports that the emergency landing was because of a faulty door, a Singapore Airlines spokesman said that “on the earlier flight into London there was a noise reported from one of the main deck doors”.
But he added that “the door was inspected by engineers on the ground in London with no findings, and the aircraft was cleared for continued operation”.
Airbus, which manufactures A380s, said in a statement that it was “following up on this issue and providing technical assistance to the airline”.
Singapore Airlines is one of the biggest operators of the A380 planes, with 19 jets in its fleet.
The British government has warned airlines not to allow Edward Snowden, an ex-CIA employee who leaked secret US surveillance details, to fly to the UK, according to reports.
The Associated Press news agency reported seeing a document at a Thai airport telling carriers to stop Edward Snowden, 29, boarding any flights.
The travel alert – reported to feature a Home Office letterhead – said Edward Snowden “is highly likely to be refused entry to the UK”.
The Home Office would not comment.
According to AP, the alert was issued on Monday by the Home Office’s risk and liaison overseas network.
The document had a photograph of Edward Snowden and gave his date of birth and passport number, the news agency reported.
It said: “If this individual attempts to travel to the UK: Carriers should deny boarding.”

It went on to warn airlines they may “be liable to costs relating to the individual’s detention and removal” should they allow him to travel.
According to the Home Office website, a charge for such a situation would be £2,000 ($3,130).
Bangkok Airways, Singapore Airlines and Malaysia Airlines confirmed they had received the notice, which was not supposed to be seen by the public, AP reported.
The Home Office does have the power to block people’s entry to the UK in certain circumstances, such as if it believes it is in the public interest to do so.
The powers had been used in the past, including to deny entry to extremist preachers and extremist European politicians.
Edward Snowden was last seen in Hong Kong, where he travelled ahead of the Guardian newspaper’s stories revealing the extent of the National Security Agency’s (NSA) programme to take data from US internet and telephone firms.
There is no suggestion that he has any intention of trying to travel to the UK.
Edward Snowden’s actions have divided opinion in the US, with some calling him a hero and others calling for him to be tried for treason.
Delta Air Lines has agreed a deal to buy Singapore Airlines’ 49% stake in Virgin Atlantic for $360 million.
Virgin Group and Sir Richard Branson will retain a 51% shareholding, and the Virgin brand will remain in place, the new partners said in a joint statement.
The deal is subject to regulatory approval in the US and Europe.
It follows a spat between Sir Richard Branson and Willie Walsh, boss of BA-owner International Airlines Group over the future of Virgin Atlantic.
Earlier, Willie Walsh offered to wager a “knee in the groin” in a bet with Sir Richard Branson over whether the Virgin brand would still be around in five years.
He was responding to a £1 million ($1.5 million) bet offered by Sir Richard Branson on Monday.

Virgin and Delta said the deal would allow them to “overcome slot constraints” and offer more flights from Heathrow.
The carriers will operate 31 peak-day round trips between the UK and North America.
“Our new partnership with Virgin Atlantic will strengthen both airlines and provide a more effective competitor between North America and the UK, particularly on the New York-London route,” said Delta boss Richard Anderson.
Sir Richard Branson said it was an “exciting day” in Virgin’s history.
“It signals the start of a new era of expansion, financial growth and many opportunities for our customers and our business.”
Singapore Airlines is selling its stake, which it has owned since 1999, because of increased competition in its local market.
airlines in particular have mushroomed, threatening more traditional carriers like Singapore Airlines.
Singapore Airlines has itself launched a low-cost carrier, called Scoot, and has been putting money into its regional service, SilkAir.
