"As always, the safety and security of passengers and crew is the highest priority for USA airlines and we remain committed to ensuring the highest levels of security are in place throughout the industry".
Officials with the U.S. Department of Homeland Security rescinded the ban in July, provided airlines and airports meet more stringent screening standards. And they could be subject to security interviews by airline employees, according to a United States government official.
"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.
Hong Kong-based Cathay Pacific Airways Ltd. said on its website that it had suspended self-drop baggage services and that passengers heading to the U.S.
Air France said it will begin new security interviews on Thursday at Paris Orly Airport and a week later, on November 2, at Charles de Gaulle Airport.
The US government announced that travellers on all inbound global flights could be questioned by airline staff before being allowed to board aircraft.
Last week was the deadline set when the Trump administration announced enhanced screening procedures for US-bound flights.
The new procedures do not apply to those who are part of TSA's Pre-Check program, which offers expedited screening for travelers who have undergone background checks.
In March, the U.S. banned passengers from taking large electrical devices such as laptops on board flights from eight mainly Muslim countries over security fears.
Most say they're ready, and they've had four months' notice.
According to CNBC, these new measures include passenger questioning and searching carry-on bags. Vaughn Jennings, a spokesman for the trade group Airlines for America, says these are "complex security measures" but the Department of Homeland Security has been flexible, which is helping airlines comply.
Association of Asia Pacific Airlines Director General Andrew Herdman said having a globally coordinated security approach made more sense than having destination-specific requirements.
The Transportation Security Administration will be requiring travelers to remove all electronics larger than a cell phone from their carry-on bags and put them in bins for X-ray screening at the security checkpoint.
