I haven't seen this reported anywhere in the news yet, perhaps WRH is the first to publish it. If you are flying overseas, eg. to Asia, watch out for the latest online booking scam where a major online ticket agency will offer you a "cheaper flight" change they probably know you will have to cancel.
In our example, the "cheaper flight" added two stops in China and one airport change across Shanghai. When I explicitly asked the ticket agency if either might require a visa, they didn't answer for days then replied, they "don't know". How could they, they only sell thousands of tickets a day to Asia. So I asked China's Consulate, where a friendly official explained, yes, either requires a visa, you can't get one at the flight, only in LA in person. Fly twice to LA to apply & pick up. (" If you just transit in one airport in China within 24 hours and fly to a third country, you do not need a visa. But in your case..." etc.)
