The TSA said in July it was imposing new security rules requiring United States domestic airline travelers to remove all electronic items larger than mobile phones such as tablets, e-readers and video game consoles from carry-on baggage for screening. All passengers traveling to the United States will be subject to new screenings.
"TSA continues to evaluate and modify its procedures to keep travelers safe", William Csontos, TSA Federal Security Director for CT, said in a statement.
An Air China official said: "We will meet the demands from the United States side, but as for the detailed measures, it is inconvenient for us to release".
"The security measures affect all individuals, global passengers and USA citizens, travelling to the United States from a last point of departure worldwide location", said Lisa Farbstein, a spokeswoman for the TSA.
"We're not going to interview all passengers, but focus on those with a certain degree of risk when checking the passengers' documents on the ground", he said.
"These measures will work in complement with the current additional screening measures conducted at the boarding gate", it said.
Cathay Pacific Airways Ltd said it would suspend in-town check-in and self bag-drop services for passengers booked on direct flights to the United States.

Airlines for America, a USA trade group, said the changes "are complex security measures" but praised U.S. officials for giving airlines flexibility in meeting the new rules. "While these are complex security measures, the flexibility provided by DHS has helped to ensure that carriers remain compliant".
Kilani said he does not know what types of questions would be asked.

The Trump administration has lifted the ban, but it comes with a tradeoff. "It's just inconvenient for the passengers".
