5 airlines to intensify security for U.S.-bound flights

Five major international long-haul airlines – Air France, Cathay Pacific, EgyptAir, Emirates, and Lufthansa – have signed on to intensify screening of all passengers, regardless of nationality, who are flying into U.S. airports, according to the TSA.

The new measures include personal interviews, an additional questionnaire, and in some cases tighter scrutiny of electronic devices and the airports themselves.

More airlines and airports are expected to come on board in the next couple of months. The TSA said the security guidelines are not set in stone and are being tailored to fit the specific needs of each airline and airport.

"As threats continue to evolve, we, and our partners around the world, will continue to work together to improve intelligence sharing and standardize best practices, while also pursuing technological advancements that will make flying more secure for everyone," TSA spokesperson Lisa Farbstein said in a statement.

The measures begin October 26, 2017, and will be rolled out in Paris next week. The TSA said the number of U.S.-bound flights affected daily will vary but is estimated to average 2,100 flights a day.
