Chinese interest in flying to the United States is also on the rise. In fact, it’s reportedly doubled over the last five years. “It’s still a huge, hot economy,” said Brian Znotins, United’s vice president of network, in an interview with the Journal. “The middle class is really booming.

Already, United has a partnership with Air China, which it will leverage as part of its commitment to servicing the country. There will likely be more cities added in the coming years, too, and potential perks for the carrier from China. “It’s not uncommon when we start a new route to have incentives,” said Znotins, although he declined to tell the newspaper more details on the subject.
