Why your next flight may go via China

It is the same if you are looking to fly from Bangkok to Los Angeles. Or from Singapore to New York.Yangzhou to Hohhot flight
In all three cases, the cheapest tickets these days are often offered by a Chinese airline.
Take the London to Sydney route. Using one of the best-known flight-finder websites to search for a ticket to fly out and back on two dates picked at random - 30 October and 12 November - the cheapest available, at the time of writing, was quoted by China Southern Airlines.
Meanwhile, if you wanted to fly between Bangkok and Los Angeles on the same dates, the lowest-priced ticket was offered by China Eastern Airlines.
So if you don't mind having a stopover in a Chinese city you might not have heard of before - how about 12 hours in Qingdao? - leisure and business travellers can often save a fair amount of money.
But how exactly are a growing number of Chinese airlines able to offer bargain prices that undercut more established rivals from Europe, the US, Asia, and the Middle East? Are they playing fair?
And how are the Chinese carriers able to secure an increasing amount of often hard-to-get landing slots around the world?
China's main airlines are undoubtedly being subsidised by the Chinese government, says Shukor Yusof, founder of Endau Analytics, a Singapore-based aviation industry research group.
These subsidies enable the carriers, such as the big three - Air China, China Eastern and China Southern - to aggressively gain market share around the world without worrying too much about any losses along the way.
"Chinese carriers do not reveal details, or specifics," says Mr Yusof. "However, taking account of the numbers that are flying, it would be fair to say that some are breaking even, many lose money, and few are able to eke out profits."
China's airlines are also benefiting from regional Chinese governments offering them subsidies to run international flights from their main cities, in the hope of putting them more on the map, and encouraging tourism and economic development.
In 2016 regional Chinese authorities outside Beijing, Shanghai and Guangzhou spent at least 8.6bn yuan ($1.3bn; £1bn) subsidising airlines, mostly towards international flights, according to data compiled by research group Civil Aviation Data Analysis.
One of the smaller Chinese carriers, Sichuan Airlines, offers services to Los Angeles from Hangzhou and Jinan, and both flights are said to rely heavily on subsidies, with less than 60% of seats full, compared with the global, industry-wide average of 81.4% in 2017.
