A monster snowstorm has struck America's north-east, causing travel chaos for Australians.
Airlines, including Qantas, cancelled around 6000 flights on Tuesday as cities braced for record snow and governors in New York, New Jersey, Pennsylvania and Virginia declared states of emergency.
Qantas' US airline partner, American Airlines, cancelled all flights into the New York region's three main airports: John F Kennedy; LaGuardia; and Newark.
Other Qantas codeshare flights from Boston and Philadelphia were also cancelled.
Qantas flight 12, a popular flight for Australian tourists flying home after American vacations, was scheduled to leave JFK at 8.55pm on Tuesday for Los Angeles but was cancelled.

Winter Storm Stella hits US Northeast, NY dodges worst
Winter Storm Stella dumped sleet and snow across the northeastern United States on Tuesday but spared New York from the worst after authorities cancelled thousands of flights and shut schools.
Blizzard warnings were in effect in parts of Connecticut, Massachusetts and upstate New York, but were lifted for New York City, the US financial capital home to 8.4 million residents, where snow turned to sleet, hail and rain.
Dire forecasts forced the postponement of the first meeting between US President Donald Trump and German Chancellor Angela Merkel in Washington until Friday, but in the end snowfall in the US capital was light.
The National Weather Service (NWS) revised down New York City's expected accumulation to four to eight inches (10 to 21 centimeters) but 10-13 inches was recorded in parts of New Jersey, upstate New York and Connecticut.
The trajectory of the storm shifted west and north, meaning up to two feet (60 centimeters) of snow were still expected to fall in parts of New England and upstate New York with strong winds causing whiteout conditions.
"The storm is not delivering as much snow as forecasted at all and that is very good for the people of New York City, but the conditions are still very dangerous out there," Mayor Bill de Blasio told reporters.
He urged people to stay indoors as much as possible, warning that snow, sleet and freezing rain would continue throughout the afternoon combined with wind gusts as high as 50 miles per hour (80 kilometers per hour).
'We're stuck'
Temperatures would dip below freezing overnight, making roads and sidewalks dangerous and a city-wide state of emergency would remain in place until midnight (0400 GMT Wednesday), he said.
Governor Andrew Cuomo said New York had been worst hit in the central part of the state where 30 inches were predicted and where some of the more than 5,000 plows mobilized would be moving to help respond.
The NWS issued a coastal flood advisory for areas around New York, but while the subway and bus services were operating, much of the city remained quiet with schools, shops and businesses largely closed as workers shovelled snow.
New York's John F. Kennedy and LaGuardia airports and Newark Liberty International Airport were largely shut, with the majority of flights cancelled, and trains heading north also suspended.
"We're stuck. We're completely at sea," said Andy McKinney, 71, on holiday from Arizona with his son after his train from New York to Boston was cancelled. "It's not the end of the world but it is inconvenient."
The United Nations headquarters closed for the day, as did the famed Metropolitan Museum of Art, one of the busiest tourist attractions in the city, and the courts. De Blasio announced that schools would re-open Wednesday.
Early trade on the New York financial markets was low in volume, though at least partly due to Wednesday's decision from the Federal Reserve on whether to raise interest rates.
'Unpredictable lady'
More than 8,200 flights were canceled Monday through Wednesday, with airports in New York, Boston, Baltimore, Washington and Philadelphia hit hardest, according to the tracking service FlightAware.
US ambassador to the United Nations, Nikki Haley, tweeted a picture of the snow saying "A great day to binge watch 'The Americans'" in reference to the thriller TV series about Russian spies embedded in US suburbia.
Trump's administration is under fire in Washington over allegations that Russia interfered in last year's US election.
"Mother Nature is an unpredictable lady sometimes," Cuomo told reporters after meteorologists conceded it was no longer going to be the worst storm of the season on the US East Coast in what has been an unusually mild winter.
In 2016, a record 27.3 inches fell in Central Park in 24 hours in a storm that paralyzed parts of the northeast and left 18 people dead.
"It has been less snowfall than we predicted, less disruption. We have no evidence of any coastal flooding along Long Island. We have no evidence of any power outages of any significance," the governor said.
The NWS said winter storm warnings were in effect from Maine down to eastern West Virginia, but snowfall further south was minimal.
A few inches of snow, sleet and ice covered the streets in the Washington area, where federal workers were allowed to arrive three hours late and the capital's subway system operated on a weekend schedule.
