Starting Thursday, US asked all airlines flying to the country nearly 2,100 daily flights from overseas to pose these questions to flyers as an additional security measure.
The new security measures come after the Trump administration previously rolled out a laptop ban and travel bans that have thrown the global travel industry into disarray.
Although security measures appear to be getting more complex, most passengers are willing to comply in the name of safety. China Airlines and Korean Airlines are just two of the carriers that have been trying to work with American regulators to ensure compliance.
The International Air Transport Association, which represents 275 airlines, did not immediately respond to a request for comment.
"We are asking customers to show up at the airport early". This is going to lengthen the amount of recommended time passengers need to check in before their flights, likely at least an hour and a half and for some airlines, up to 3 hours before take-off. It also halted its in-town check-in and self bag-drop services for direct flights to the U.S.
Travelers on all non-stop flights to the United States, including those from Singapore, should be prepared for tighter security checks that may include being questioned at check-in and boarding.
Alexandre de Juniac, CEO of the International Air Transport Association, said the industry understood security threats to aviation were made regularly but in this case the USA government had not shared any specific dangers before announcing the initial Middle East and North Africa electronic device restrictions in March.
United States officials said the changes were aimed at protecting the country's national security. "That is something that is very concerning and disturbing".
The Association of Asia Pacific Airlines recently called for security measures to be risk-based and proportionate.
Travellers may also be asked to switch off their electronic devices, including phones. Some of those new requirements take effect this week as well.
The new screening process is meant to help avoid bans on certain electronics, like laptops, in the cabin.
