politics - US airlines vie for more lines as customers withdraw

Who is issuing visas for space when Americans and Chinese cooperate together, I wondered while going over de headlines and saw this piece by Ellen Sander. You could not imagine what kind of problems the Chinese would have to enter the US after returning from space.
Three more US airline companies want to have more flights to China: who are they going to look at to buy their seats, I wonder.
The US visa crisis is getting worse, after so many Chinese visitors were refused for the Las Vegas exhibition. CTN reports that also companies whose people got a visa and now withdrawing in solidarity and are looking for alternatives in Europe.
